Dell Ivy Bridge Latitude laptop offers 32.7 hours battery life

Dell on Thursday announced Latitude business laptops with Intel's latest Core processors that can provide around 33 hours of battery life, but only when combined with attached battery packs.

The new Latitude E-series laptops will come with screens ranging in size from 12.5 to 15.6 inches. The company achieved 32.7 hours of battery life on a Latitude E6430, which is a business laptop with a 14-inch screen and Intel's latest Core processor, code-named Ivy Bridge.

The long battery life was reached with a nine-cell battery, and batteries that plug into the bay and under the laptop. The battery life was measured based on average usage of the laptop, company officials said during aninterview.

Dell is trying to load up as much battery as it can on laptops, officials said. For example, users can remove an optical drive from a bay and replace it with a battery.

Some of the power-saving benefits also may have come from using solid-state drives, which are considered more power-efficient than hard drives that spin. Intel's Ivy Bridge processors also are more power-efficient and help save power through features like the ability to shut down idle cores.

Intel provided more details on the Ivy Bridge processors on Thursday, saying the chips are more power-efficient and faster on applications and graphics than predecessors. The chips will be officially unveiled next week at the Computex trade show in Taipei.

Dell is getting consistent, if not slightly higher, results on battery life as tests continue on other Latitude E-series laptops, said a Dell spokeswoman. Beyond the E6430, the company announced E6230 (12.5-inch screen),E6330 (13.3-inch), and E6530 (15.6-inch) laptops. Pricing on the laptops were not immediately available.

The new laptops also include the thin-and-light E6430S, which is a 14-inch laptop built into a frame typically used for laptops with 13.3-inch screens. The E6430S provides a glimpse of the company's future thin-and-light laptops, which will be highly portable but also have strong security and remote management features.

Dell is also tuning its business laptops for enterprises by adding virtualization and device management capabilities, said David Lord, director of product planning and marketing. The key is to be able to provide the mobile tools capable for a worker to access data at any time, while reducing the cost of servicing the laptop. Some of the new laptops come with Intel's VPro feature, which allows system administrators to remotely manage the laptop.

Dell also announced the ruggedized Latitude E6430 ATG laptop, which can withstand extreme temperatures and environments. The new laptops also have USB 3.0 ports, Ethernet, Wi-Fi and Bluetooth options. Optical drives are also available depending on the model.

An excellent business laptop

The Edge E320 is made out of hard plastic that feels soft and rubber-like, yet also quite smooth (and around 10 per cent of the laptop is constructed from recycled material). The unit has an understated design, and even the most determined Lenovo haters (Mac fans) in our office thought it looked good. We think it’s one of the better looking Lenovo products and we’re glad Lenovo hasn’t gone overboard with its design. It’s not the same as the firstLenovo ThinkPad Edge that we saw back in Fenruary 2010, but there are similarities, especially with the keyboard.

It’s a laptop that feels good to use and it’s comfortable to handle. At 1.8kg, it’s not super-light, but it also doesn’t feel heavy when you carry it around or use it in your lap. It ships with a power adapter that’s around 100mm long and 30mm thick, so the whole package provides good portability. The 13.3in screen is held in place by strong hinges and it has a grey trim around the edges, just to make it stand out a little.

With the screen closed, the Edge E320 is about 28mm thick, but the base itself is around 21mm at its thickest point. You won’t find an optical drive in the base, but you will find an HDMI port, VGA, Gigabit Ethernet, an SD card slot, a combination headphone and microphone port and three USB 2.0 ports (one doubles as an eSATA port and two of them can be used to charge devices even when the laptop is off). The right side of the base has a vent with a visible, thick copper heat sink and a fan is installed to keep things cool. The fan makes a slightly annoying whirring noise even when the laptop is being used to just browse the Web, and it gets a little louder when the CPU is under a full load.

Other things that we like about the keyboard include the dedicated Print Screen key, the little Page Up and Page Down keys, which sit just above the left and right arrow keys; the reversed F-keys, which allow you to change brightness and volume and other system functions without having to press the Function key — this can be changed in the BIOS if you don’t like it.

In addition to the keyboard, there are many other little details about this laptop’s design that we appreciate. The power LED is inconspicuous as it doubles as the dot in the ‘i’ of the palmrest’s ThinkPad logo. There aren’t any bright LEDs on this laptop and it’s a joy to use at night. However, we do wish that the keyboard was backlit — the spacebar actually has a backlight (or keyboard light) logo on it, but nothing happens when you press it in conjunction with the Function key — it’s such a tease. There is no backlight option with this model.

The bottom panel of the Edge E320 comes off easily and we love the fact that the screws are designed to stay with the panel — you’ll never lose them. The overall layout of the laptop is clean and all components are easy to access — you can even replace the CPU without too much trouble. There are two memory slots (one free), one 2.5in hard drive bay, a Wi-Fi module (a dual-band Broadcom 2×2 11a/b/g/n Wireless LAN PCI Express Half Mini Card Adapter) and a Mini PCI Express slot. The Mini PCI Express slot can be used to accommodate a solid state drive.

Specifications and performance
The CPU is an Intel Core i3-2310M with a 2.1GHz speed, two cores and Hyper-Threading. Along with 4GB of DDR3 SDRAM, a 320GB, 7200rpm hard drive (Seagate ST320LT007-9ZV142) and integrated Intel HD 3000 graphics, the performance of the ThinkPad Edge E320 is fast for regular office work and even multimedia tasks. You can use it to encode music, edit video and convert files, but it can’t be used effectively for gaming.

In our Blender 3D rendering test, the Edge 320 recorded a time of 58sec, while in our MP3 encoding test it recorded 1min 7sec. These results are almost identical to the 13in HP ProBook 5330m laptop, which uses the same CPU. However, it was a little slow in our DVD transcoding test, in which it took 1hr 12min. The HP completed that task in 1hr 6min. In 3DMark06, the Edge recorded a score of 3493, while in our hard drive transfer test a rate of 33.65 megabytes per second was attained, which is good.

Battery life
One area in which the ThinkPad Edge 320 shines is battery life. Its 63 Watt-hour lenovo laptop battery lasted 5hr 13min in our rundown test, in which we disable power management, enable Wi-Fi, maximise screen brightness and loop an Xvid-encoded video. It’s a very good time for a 13in laptop and you can get even more life out of it if you enable one of the many power schemes that are available.

The battery utility in this ThinkPad is one of the most comprehensive we’ve seen. It can give you intricate details of the battery, including how much power it is consuming, how much power is left, and even how long it will take for the battery to fully recharge. You can also set the recharge capacity to 80 per cent in order to improve the overall life of the battery (in terms of charging cycles). There are many other facets to this utility, all you have to do is click on the advanced button to see them all.

Conclusion
There some things about the ThinkPad Edge E320 that could be better. The keyboard could use a backlight, a USB 3.0 port would be nice, the screen could use better brightness and vertical viewing angles, and it could use biometric security (it has a Computrace-capable BIOS though).

Furthermore, we also think it’s about time Lenovo ditched the TrackPoint pointing device — it’s useful in confined spaces and it doesn’t get in the way while typing, but we think it’s unnecessary — and we wish the touchpad was a little better. While it’s a very responsive pad with good gesture support, the placement of the left- and right-click buttons underneath the pad makes it almost impossible to perform right-click and drag operations.

Permanent battery defects include high internal resistance, elevated self-discharge, electrical short and capacity fade. Poorly designed chargers, exposure to excess heat, harsh charge and discharge cycles, and inappropriate storage contribute to early aging. Let’s examine the cause of these non-correctable battery problems and explore what we can do to minimize them.
Low-capacity Cells

A manufacturer cannot predict the exact capacity when a battery comes off the production line, and this is especially true with lead acid batteries that involve manual assembly. Fully automated cell production in “cleanrooms” also causes performance differences, and as part of quality control, each cell is measured and segregated into categories according to their inherent capacity levels. The high-capacity A-cells are reserved for special applications and sold at premium prices; the large mid-range B-group goes to commercial and industrial markets; and the low-grade C-cells may end up as consumer products in department stores. Cycling will not significantly improve the capacity of the low-end cell, and even though the cell may look good, the buyer must be aware of differences in capacity and quality, which often translate into life expectancy.

Matching of cells according to capacity is important, especially for industrial batteries. No perfect match is possible, and if slightly off, nickel-based cells adapt to each other after a few charge/discharge cycles similar to the players on a winning sports team. High-quality cells continue to perform longer than the lower-quality counterpart, and the cells degrade at a more even and controlled rate. Lower-grade cells, on the other hand, diverge more quickly with use and time, and failures due to cell mismatch are more widespread. Cell mismatch is a common cause of failure in industrial batteries. Manufacturers of professional power tools and medical equipment are careful in the choice of cells to attain good battery reliability and long life.

Let’s look at what a weak cell does in a pack that is strung together with strong ones. The weak cell holds less capacity and is discharged more quickly than the strong brothers. Going empty first, the strong brothers overrun this feeble sibling and the resulting current on a continued discharge pushes the weak cell into reverse polarity. Nickel-cadmium can tolerate a reverse voltage of minus 0.2V and a reverse current of a few milliamps, but exceeding this level will cause a permanent electrical short. On charge, the weak cell reaches full charge first and it goes into heat-generating over-charge while the strong brothers still accept charge and stay cool. The low cell experiences a disadvantage on both charge and discharge. It continues to weaken until finally giving up the struggle.

The capacity tolerance between cells in an industrial battery should be +/– 2.5 percent. High-voltage packs designed for heavy loads and wide adverse temperature ranges should have lower tolerances. There is a strong correlation between cell balance and longevity.

Li-ion cells share similar deficiencies with nickel-based systems and need management. The mandatory protection circuit supervises the serially connected cells by clamping the voltage when exceeding 4.25 and 4.35V on charge, and disconnecting the pack from discharge when the weakest cell drops to between 2.50 and 2.80V/cell. This prevents the stronger cells from pushing the depleted cell into reverse polarization. The protection circuit acts like a guardian angel that shields the weaker siblings from being bullied by the stronger brothers. This may be help to explain why Li-ion packs for power tools last longer than nickel-based batteries, which normally do not have a protection circuit.
The capacity of quality Li-ion cells is consistent and the self-discharge is low. A problem arises when the cells exhibit a discrepancy in self-discharge. This can be attributed to lower-quality cells or high-temperature spots in a large automotive battery, which hastens aging. Balancing is required and there are two methods: Passive balancing bleeds the high-voltage cells; active balancing shuttles the extra charge from higher-voltage cells to the lower-voltage cells without burning the energy. Active balancing is the preferred method on EVs.

With use and time all batteries become mismatched, and this also applies to lead acid. Shorted cells and those having high self-discharge are a common cause of cell imbalance and lead to subsequent failure. Manufacturers of golf cars, aerial work platforms, floor scrubbers and other battery-powered vehicles recommend an equalizing charge of 3–4 hours if the voltage difference between the cells is greater than +/– 0.10V, or if the specific gravity varies more than 10 points (0.010 on the SG scale). An equalizing charge is a charge on top of a charge that brings all cells to full-charge saturation. This service must be administered with care because excessive charging can harm the battery. A difference in specific gravity of 40 points poses a performance problem and the cell is considered defective. A 40-point difference is one cell having an SG of 1.200 and another 1.240. A charge may temporarily cover the deficiency, but the flaw will resurface after a few hours of rest due to high self-discharge.
Shorted Cells

Manufacturers are at a loss to explain why some cells develop high electrical leakage or a short while still new. The culprit might be foreign particles that contaminate the cells during manufacture, or rough spots on the plates that damage the delicate separator. Clean rooms, improved quality control at the raw material level, and minimal human handling during the manufacturing process have reduced the “infant mortality rate.”
Applying momentary high-current bursts to repair a shorted NiCd or NiMH cell has been tried but offers limited success. The short may temporarily evaporate but the damage in the separator remains. After service, the repaired cell may charge normally and reach correct voltages; however, high self-discharge will likely drain the battery and the short will return.

It is not advised to replace a shorted cell in an aging pack because of cell matching. The new cell will always be stronger than the others. Consider the biblical verses: “No one sews a patch of unshrunk cloth on an old garment. If he does, the new piece will pull away from the old, making the tear worse. And no one pours new wine into old wineskins. If he does, the wine will burst the skins, and both the wine and the wineskins will be ruined” (Mark 2:21, 22 NIV). Replacing faulty cells often leads to battery failures within six months. It’s best not to disturb the cells. Instead, allow them to age naturally as an intact family.

Shorts or high leakage in a Li-ion cell are uncommon. If this occurs, the cell becomes unstable and a massive amount of power can dissipate, leading to a possible venting thermal breakdown. Such a leak can be compared to drilling a small pinhole into a high-pressure gas pipeline and holding a match to it. The resulting explosion could rupture the pipe. Similarly, the rushing current in the cell heats up the tiny malfunction, causes a major leak and releases all energy within seconds. (Read more about Safety circuits for modern batteries)

The loss of electrolyte in a flooded lead acid battery occurs through gassing, as hydrogen escapes during charging and discharging. Venting causes the electrolyte to become more concentrated and the balance must be restored by adding clean water. Do not add electrolyte, as this would upset the specific gravity and shorten battery life through excessive corrosion.

Permeation, or loss of electrolyte in sealed lead acid batteries, is a recurring problem that is often caused by overcharging. Careful adjustment of charging and float voltages, as well as operating at moderate temperatures, reduces this failure. Replenishing lost liquid in VRLA batteries by adding water has limited success. Although the lost capacity can often be regained with a catalyst, tampering with the cells turns the stack into a high-maintenance project that needs constant supervision.

In many ways, a battery behaves like a human being; it senses the kindness offered and delivers on the care and attention given. Looking after the battery well will return the benevolence bestowed and deliver good performance over a long life. There are exceptions, however, as any parent raising a large family will know, and the generosity given may not always deliver the anticipated returns.

To become a good custodian, we must understand the basic needs of a battery, a subject that is not taught in school. This section teaches what to do when the battery is new, how to feed it the right “food” and what to do when putting the pack aside for a while. The next articles also look into restrictions when traveling with batteries by air and how to dispose of them when their useful life has passed.

Just as we cannot predict a person’s life expectancy at birth, we cannot date-stamp a battery. Some packs live to a great old age while others die young. Incorrect charging, harsh discharge loads and exposure to heat are the battery’s worst enemies. Although we have waysto protect a battery, the ideal situation is not always attainable, and as battery custodians we try to do our best. This chapter discusses how we can get the most from our batteries.

Priming a new Battery

Rechargeable batteries may not deliver their full rated capacity when new and will require formatting. While this applies to most battery systems, manufacturers of lithium-ion batteries disagree. They say that Li-ion is ready at birth and does not need priming. Although this may be true, users have reported some capacity gains by cycling these batteries after long storage.

What’s the difference between formatting and priming? Both address capacities that are not optimized and can be corrected with cycling. Formatting completes the manufacturing process and occurs naturally during early usage when the battery is being cycled. Priming, on the other hand, is a conditioning cycle that is applied as a service tool to improve battery performance during usage or after prolonged storage. Priming relates mainly to nickel-based batteries.

Formatting of lead acid batteries occurs by applying a charge, followed by a discharge and recharge as part of regular use. Do not strain a new battery by giving it extra-heavy duty right away. Gradually work it in with moderate discharges like an athlete trains for weight lifting or long-distance running. Lead acid typically reaches the full capacity potential after 50 to 100 cycles. Do not over-cycle on purpose; this would wear the battery down too quickly.

Manufacturers advise to trickle charge a nickel-based battery for 16 to 24 hours when new and after a long storage. This allows the cells to adjust to each other and bring them to an equal charge level. A slow charge also helps to redistribute the electrolyte to eliminate dry spots on the separator that might have developed by gravitation.

Nickel-based batteries are not always fully formatted when they leave the factory. Applying several charge/discharge cycles through normal use or with a battery analyzer completes the formatting process. The number of cycles required to attain full capacity differs between cell manufacturers. Quality cells perform to specification after 5 to 7 cycles, while others may need 50 or more cycles to reach acceptable capacity levels. Lack of formatting might cause a problem when the industrial user expects a new battery to work to specification right out of the box. Organizations using batteries for critical applications often verify performance through a discharge/charge cycle as part of quality control. Automated analyzers (Cadex) apply as many cycles as needed to achieve full capacity.

Cycling also restores lost capacity when a nickel-based battery has been stored for six months or longer. Storage time, state-of-charge and the temperature under which the battery was stored govern the recovery. The longer the storage and warmer the temperature, the more cycles will be required to regain full capacity. Battery analyzers help in the priming functions.

Some scientists believe that with use and storage, a passivation layer builds up on the cathode of a lithium-ion cell. Also known as interfacial protective film (IPF), this layer restricts ion flow and increases the internalresistance. In the worst cases, the phenomenon can lead to lithium plating. Charging, and more effectively cycling, is known to dissolve the layer. Scientists do not fully understand the nature of this layer, and the few published resources on this subject only speculate that performance restoration with cycling is connected to the removal of the passivation layer. Some scientists deny outright the existence of the IPF, saying that the idea is highly speculative and inconsistent with existing studies. Another layer is the solid electrolyte interphase (SEI), which is said to form at the anode on the initial charge. SEI is an electric insulation yet provides sufficient ionic conductivity for proper function.

Lithium-ion is a very clean system and does not need formatting when new, nor does it require the level of maintenance that nickel-based batteries do. The first charge is no different than the fifth or the 50th. Formatting makes little difference because the maximum capacity is available right from the beginning. Nor does a full discharge improve the capacity once faded. In most cases, a low capacity signals the end of life. A discharge/charge may be beneficial for calibrating a “smart” battery, but this service only addresses the digital part of the pack and does nothing to improve the electrochemical battery. Instructions to charge a new battery for eight hours are seen as “old school” from the nickel battery days.

Whatever the truth may be, there is no parallel to “memory” of NiCd batteries, which require periodic cycling. The symptoms may appear similar but the mechanics are different. Nor can the effect be compared to sulfation of lead acid batteries.

As the name suggests the tablet has a 7in screen as is therefore a small tablet. The Nexus 7 is respectably thin at 10.9mm and very light at 336g.
It's designed to be held in portrait mode predominantly and we found it very comfortable in one hand, in either orientation. You can easily reach right round the tablet with one hand, like you would with a smartphone. The pint-sized dimensions of 120 x 199mm mean you can also put the tablet in the back pocket of your jeans or the inside pocket of a jacket.

The Nexus 7 is available to starting at the startlingly low price of £159. It's the first device to ship with Android 4.1 Jelly Bean and offers a 7in screen and a quad-core processor. See also: Google Nexus 7 tablet vs Apple iPad comparison review.

The front is one piece of glass only interrupted by a camera and light sensor surrounded by a silver metal frame. The back of the Nexus 7 is a dark brown, effectively black, textured cover which has a rubbery feel. The finish on the rear cover provides a good amount of grip and feels nice to the touch.
Physical buttons and ports are minimal with a power button and volume rocker on the right hand edge while a microUSB port and headphone jack reside on the bottom of the tablet.
There's also a 4-pin connector at the bottom of the left hand edge for use with future accessories like a docking station and a pair of stereo speakers sit at the bottom of the rear cover.

We've come to expect tablets with a price tag under £200 to offer poor build quality. However, the Nexus 7 throws this trend out of the window. Google's tablet is well made and feels like a premium product, almost making us double check the price.
The scratch resistant Corning glass sits neatly flush with the metal frame and the same is true of the rear cover. The buttons and ports also feel solid, not cheap and nasty like we've come to expect from budget tablets.

One very small quibble we found was rippling on the screen at the top and bottom edges. This is something we saw on the HTC One X and happened when putting pressure on the display. We're not suggesting that everyone will be pushing the screen like it's one giant physical button but it is more worrying in terms of traveling with the Nexus 7 in a bag, for example.

The Nexus 7 has a surprisingly good line-up of hardware for a tablet with a budget price tag. For starters it uses the same nVidia Tegra 3 quad-core processor found in many high-end tablets. This is backed up by a healthy 1GB of RAM.
In the GeekBench 2 test the Nexus 7 scored highly with an average of 1452 over three runs. This reflects how smooth the tablet runs and performs.

The highlight for us is the 7in screen which uses a backlit in-plane switching ( IPS) panel with a resolution of 1280 x 800. The display has excellent contrast, brightness and viewing angles. The level of detail is high thanks to the 1280 x 800 resolution giving a pixel density of 216ppi. This is higher than the Samsung Galaxy Tab 2 (7.0) which costs more.
We found the screen good for browsing the web, playing games but even more so for watching films and other video content.

Storage is limited at either 8GB or 16GB with the latter costing £199 compared to £159. It's worth noting that the full quoted capacity won't be available since the Android operating system uses around 2GB of the space.
Unfortunately a cost cutting measures mean there's no microSD for expansion. This is probably the biggest let down about the Nexus 7. Asus told us there is less focus on local storage with content stored in the cloud. However, the Nexus 7 isn’t equipped with 3G capabilities.
There is 802.11b/g/n Wi-Fi so you can tether the Nexus 7 to a smartphone for data on-the-go. Other connectivity includes Bluetooth, GPS and a near-field communications ( NFC) chip.

In an attempt to save costs there's no rear facing camera present on the Nexus 7. This doesn't bother us much seeing as smartphone cameras tend to be better and more suitable to use. More importantly than a rear facing camera, there is a fairly decent 1.2Mp front facing camera for video chats, though.
There's no camera app pre-installed so you'll have to visit the Play Store to get some software to utilise the camera. We found the picture quality easily adequate for taking a few snaps and video calling.

someone opinion:

This tablet will revolutionise the tablet market.
will it steal sales from other manufacturers?
It doesnt really matter.

in 12 months there will be over 20 mainstream android tablets and just like the mobile sector, they will obliterate Iphone/Microsoft user-base. not just in the west, but globally.
Welcome to the tablet market google it should be interesting.

Google G1 Mobile phone had very poor sales initially, but google came out saying it had been a "success" - what are their reasons?
The reason is Google do not care whether their own branded product is a success or not. they are an online data/media/advertising company, they only care about 2 things, collecting data and advertise-able user-base.

This tablet intends to make android tablets big news to consumers. To make them aware of the possibilities, and to create a demand for the android tablets.
Look how many android phones are out now and how many people use compared to when the G1 was launched?
Google just drop in to release a Google own brand product every time the market itself needs a small push.
But just because people do not buy the Google Nexus phone for example, Google is still making money from every other android device.
This tablet is already a success.

After Successful Pilot Program Dubbed 'Project Sputnik', Dell Launching Developer Laptop

After playing a successful pilot program, Dell will be releasing an Ubuntu developer laptop codenamed Project Sputnik later this year. The project will essentially be an XPS13 Ultrabook with an Ubuntu 12.04 build that runs several developer tools.

The Ubuntu developer laptop specializes in client-to-cloud solutions. The laptop allows developers to run simulations of cloud solutions called " microclouds" where they can test environments before deploying them. The laptops use LXC virtual environment containers to run the microclouds. The "microclouds" can be deployed to Ubuntu instances running on Amazon OpenStack and eventually Microsoft Azure clouds.

Dell will be making an Ubuntu install image available that's customized for the XPS13 computer just in case people want to run dual-boot systems with Ubuntu and Windows. The Ubuntu developer laptop will be packed with 4GB of RAM, an Intel Core i7 processor and 256GB of solid-state hard drive storage. The new laptop will sell just under the price of the current XPS13 laptops, which sell for $1499.

Dell was one of the first major PC-makers to embrace the Ubuntu distribution of Linux. The company began selling Ubuntu on its laptops in 2007 before drastically pulling back on its Linux offerings. Still, the Ubuntu community has remained incredibly strong and according to a TechCrunch interview with project lead Barton George, Dell believes there's enough interest to justify Ubuntu's return to Dell's product line.

It's unclear how the Dell will go about advertising the developer's version of its laptop or if they'll bother to market it at all. It's clear that he laptop is being created specifically for power users and one's that are using Ubuntu cloud applications.

"Since we announced project Sputnik a little over two months ago, we have continued to be amazed by the amount and quality of interest and input we have received," said George in a statement. "By listening to developers, Dell can provide them with solutions and products to help make them more productive and allow for greater innovation."Introduction
Dell's 2012 approach to its iconic Alienware gaming laptops? Go big, or go home (to your home planet, presumably).

Until recently, the Alienware M14x was the middle child in the company's gaming-laptop lineup, falling between the ultraportable M11x model and the much larger M17x and M18x machines. (The number in the names of the machines describes the screen size.) That's changed in 2012, however. With the latest refresh of these popular gaming laptops, now integrating the latest mobile CPU and graphics technology (namely, Intel's Ivy Bridge processors and Nvidia's Kepler graphics), Alienware decided not to update the little M11x. That leaves the laptop we're looking at here, Alienware's M14x R2, as the company's current-generation entry-level gamer.

Alienware M14x R2 Review

With gaming laptops, what's entry-level is relative, of course. The starting price for the M14x R2 is $1,099, shipping with an Intel "Ivy Bridge" Core i5 processor, a GeForce GT 650M graphics chip (based on Nvidia's latest graphics architecture, code-named "Kepler"), 6GB of RAM, and a 500GB hard drive. As you'd expect from any Dell machine, however, the Alienware M14x R2 is customizable to the max. We looked at a review unit outfitted with a slew of upgrades: a faster Core i7 CPU, a 32GB mSATA solid-state drive ( SSD) for faster boot times and game loads (paired with a larger 750GB hard drive), 8GB of RAM, and the same GT 650M graphics chip, but augmented with twice the dedicated memory (2GB). The laptop also got a screen upgrade that bumped up the resolution to 1,600x900, versus the $1,099 model's rather ordinary 720p (1,366x768) panel.

All those extras certainly mean a more powerful machine, and they illustrate the level of customizability available in the line. In the case of our test model, though, they also pushed up the price more than $500, to $1,604. That edged the machine into the price range of larger 17-inch offerings, like Alienware's own M17x, or the MSI GT70, both Editors' Choice winners. Those systems certainly weigh more—a lot more—than the M14x's 6.5 pounds, but they have larger, higher-resolution (1080p) panels, and they sport higher-end Nvidia graphics chip options for better performance.

That puts the Alienware M14x R2 in a pricing pickle. Even if you can't handle a hulking system with a 17-inch screen, MSI's 15-inch GT60 sells for $1,499, with more RAM, a larger hard drive, and more powerful GeForce GTX 670M graphics. Admittedly, the graphics chip there is based on last-generation Nvidia architecture, and there's no mSATA SSD. But the overall specs are better with the MSI machine, and it's priced about $100 less than our test configuration of the Alienware. (Plus, even if portability is important, the MSI GT60's 7.7-pound weight isn't prohibitively heavier than the M14x's 6.5 pounds.)

Unless you truly need the portability that the M14x offers, and you don't want to consider even smaller offerings like Maingear's Pulse 11 (which, when we wrote this, sold for $1,284 with similar components to the M14x R2, minus the mSATA SSD), we'd stick with a larger gaming laptop like Alienware's excellent M17x or MSI'sGT70. The M14x is certainly a solidly built, impressively tricked-out system, but it's pricey for what you get, especially once you load it out with options like in our test configuration. In sum, our advice: You probably do want to go bigger.

Lijkt het alsof de accu van uw computer altijd leeg is, hoe vaak u deze ook oplaadt? Waarschijnlijk is het dan tijd om de accu te vervangen. Elke accu heeft een nominale capaciteit, dit is het energieniveau waarvoor de accu is ontworpen. Na verloop van tijd verliezen accu's hun vermogen om een lading vast te houden. Dit betekent dat zelfs bij een volledig opgeladen accu het werkelijke energieniveau dat de accu kan bevatten, achteruitgaat.Accu/Batterij GATEWAY 4012GZ

Een indicatie dat de accu achteruitgaat, is een kortere gebruikstijd en een kortere tijd om de accu op te laden. Accu/Batterij PANASONIC EY3530NQMKW Als u merkt dat u steeds korter met de computer kunt werken wanneer deze niet is aangesloten, heeft de accu waarschijnlijk veel van het vermogen verloren om een lading vast te houden. Een ander teken dat de accu achteruitgaat, is dat het korter duurt om opnieuw op te laden.Accu/Batterij PANASONIC EY3531 Met een accu die op zijn retour is, kan ook de computer onverwacht worden uitgeschakeld of in de sluimerstand worden gezet, zelfs als de accumeter aangeeft dat er voldoende capaciteit resteert (70 of 80 procent).Accu/Batterij GATEWAY 4024GZ

Gelukkig kunt u in Windows bepalen of de accu nog steeds een volledige lading kan vasthouden. Accu/Batterij PANASONIC EY3530NQKWWanneer de accu is gedegenereerd naar 40 procent van de oorspronkelijke capaciteit (dit betekent dat de accu slechts 40 procent of minder van de ontworpen capaciteit kan bevatten nadat deze is opgeladen), ziet u een melding via het pictogram van de accumeter dat de batterij achteruitgaat. Deze melding is nieuw in Windows 7 (in eerdere versies van Windows wordt niet gemeld dat de accu achteruitgaat). Als u deze melding niet wilt ontvangen, kunt u deze uitschakelen door het selectievakje onder de accumeter uit te schakelen.Accu/Batterij GATEWAY 4025GZ

Accumeter met de melding dat de accu achteruitgaat Accu/Batterij GATEWAY 4026GZ
Bij veel accu's ondervindt u al veel eerder problemen voordat ze zijn gedegenereerd naar 40 procent van de oorspronkelijke capaciteit. Veel computerfabrikanten bieden bovendien programma's waarmee u de prestaties van de accu kunt meten.Accu/Batterij PANASONIC EY3531NQWKW Deze programma's zijn mogelijk beter afgestemd op specifieke accuproblemen en moeten eerst worden gebruikt om de conditie van de computeraccu te controleren. Zie Oplossingen voor algemene accuproblemen voor informatie over oplossingen voor dit probleem.Accu/Batterij PANASONIC EY3793

Opmerking

Sommige computerfabrikanten geven aan dat de ontworpen capaciteit van hun accu's gelijk is aan het niveau van de laatste volledige lading, dus het is mogelijk dat de accu onder de meldingsdrempel is zonder dat u een waarschuwing krijgt.Accu/Batterij HITACHI DS 14DFLG Als de computeraccu voortdurend te snel leegraakt terwijl de accumeter aangeeft dat de accu volledig is opgeladen, is het mogelijk tijd om de accu te vervangen.

De accumeter is een handige functie in het systeemvak van de taakbalk van Windows waarmee u eenvoudig een overzicht houdt van het energieverbruik van de computer.Accu/Batterij HITACHI DS 14DL Het accupictogram geeft aan of de laptop is aangesloten op het lichtnet of op accuvoeding werkt . Wanneer u naar de accumeter wijst, ziet u het percentage resterende accucapaciteit en een schatting van de tijd totdat de computer moet worden aangesloten op netstroom.Accu/Batterij Samsung NC110
Wanneer u op het accupictogram klikt, is meer informatie beschikbaar: bijvoorbeeld welk energiebeheerschema u gebruikt en, bij meerdere accu's, hoeveel lading de secundaire accu nog heeft.

De accu sparen met energiebeheerschema's

Een van de eenvoudigste manieren om de accu te sparen zonder de prestaties van de computer te beperken, is het gebruik van een van de ingebouwde energiebeheerschema's die bij Windows worden geleverd. Een energiebeheerschema is in principe een verzameling instellingen voor hardware en software die bepaalt hoe de computer stroom verbruikt. Bij Windows worden twee energiebeheerschema's geleverd die nuttig zijn voor laptops:Accu/Batterij Samsung NP-N145

Gebalanceerd.Accu/Batterij KOHJINSHA SA5ST12F Dit is het schema dat standaard wordt gebruikt voor de meeste laptops. Het biedt u volledige prestaties en helderheid van het beeldscherm wanneer dat nodig is en bespaart energie gedurende perioden waarin er geen activiteiten op de computer plaatsvinden.Accu/Batterij LG K1-223PR

Energiebesparing. Dit schema stelt u in staat de accu optimaal te benutten. Het bespaart energie door de prestaties van het systeem en de helderheid van het scherm te reduceren.Accu/Batterij LG K1-223VG

Naast de energiebeheerschema's die bij Windows worden geleverd, biedt uw computerfabrikant mogelijk aanvullende schema's.Accu/Batterij HITACHI DS 14DV U kunt ook uw eigen energiebeheerschema maken of instellingen van een bestaand schema aanpassen.

Optimaal gebruik van de accuAccu/Batterij LG K1-2245G

Naast het gebruik van energiebeheerschema's om een batterijlading optimaal te benutten, is het ook belangrijk om de accu te onderhouden om te zorgen voor een zo lang mogelijke levensduur.Accu/Batterij LG K1-2249A9

Zorg dat u de instructies voor het opladen en onderhoud van de accu van de fabrikant opvolgt. Gebruik alleen een lader en netsnoer die door de fabrikant worden geleverd.Accu/Batterij KOHJINSHA SA5KX08LCN

Zorg dat de accu niet te heet (of te koud) wordt. Een hete accu duidt op problemen en betekent meestal dat de accu niet juist werkt. In dat geval moet u direct stoppen met het gebruik van de accu. Zorg verder dat de accu niet wordt blootgesteld aan extreme temperaturen. Accu's werken het best bij kamertemperatuur. Voorkomhet gebruik (en zelfs de opslag) van accu's onder extreme temperatuursomstandigheden.Accu/Batterij KOHJINSHA SA5ST08A

Gebruik de accu zodat deze niet lui wordt. Gebruik de computer niet altijd op netstroom. Het wordt aangeraden de laptopaccu ongeveer eens per maand te ontladen en weer op te laden. Zorg verder dat de accu voldoende leeg is voordat u deze weer oplaadt.Accu/Batterij KOHJINSHA SA5ST12A
