If the charge in your laptop battery is dying out noticeably faster, you may need to replace it. Battery performance is affected by many factors like the environment, age and frequency of utilization.

Every battery has a certain number of charge cycles specified by the manufacturer and indicates the number of times you can charge it – this figure is around 400 – 1200 for a standard Lithium-ion laptop battery. Once this limit is crossed, the performance begins to deteriorate.

Depending on the devices available in the laptop and their usage, the battery might be able to power it for 2-3 hours before it needs to be recharged. Normal lifetime is in the range of 1.5 – 2 years. If you use the laptop continuously and recharge the battery several times a day; it may need to be replaced well before the time frame specified by the manufacturer.

These steps must be followed for battery replacement:

1. Buy a New Battery – Make sure you purchase a replacement that is compatible with your laptop.

2. Unpack the New Battery – Remove all packaging material and keep have the new battery ready to be popped in immediately.

3. Undock Laptop – If your laptop is connected to a docking device, you need to unlock it before attempting to replace the battery.

4. Turn Off Laptop – You may not want to lose any files you are working on or risk corruption of software, so it may be better to turn off the laptop.

5. Unplug AC Power/Internet Connection – It is a good practice to disconnect your laptop from the AC outlet, Internet and Telephone before replacing the battery.

6. Flip the Laptop Over – Most laptops have the battery release mechanism on the underside of the laptop. If you are not sure where you should look you can refer to the documentation of the laptop or have Technical support guide you.

7. Unlock and Remove Old Battery – Laptop batteries usually use a two-step locking mechanism, first there are latches that need to be released and then a sliding motion has to be performed to release it completely. Your documentation can be invaluable in this.

8. Position New Battery – Follow the reverse process for fixing the new battery. First slide and then latch the new battery. If the latches get stuck, you may need to adjust the positioning.

9. Charge Battery – Bring laptop to usual position; replace all the cables that you disconnected earlier, including the AC power. Charge your battery for the duration specified by the manufacturer before using it.

Today we will look at an exciting ultra-compact portable computer optimized for today’s life and travels. The DELL Inspiron XPS system based on Intel Merom processor proved an excellent solution. Read more in our review!

The life of a truly modern man is like a train that is steadily speeding up from its station towards an unknown destination. It is getting faster and faster every moment, and there’s no stopping or even pausing this process. Living at a high speed, the modern man regards time as a great value. Some people are even dreaming about extra hours in the day that would sum up into extra days monthly. To avoid floundering in such unreal dreaming, you can put to good use those hours that you’d just waste otherwise. You only need a portable digital companion, a notebook computer.

There is, however, a list of minimum requirements this digital companion must comply with to satisfy its owner. The notebook must be light and small, yet easy to work with. It must have high-performance but economical components so that it could last long on the dell xps m1210 battery. A large selection of wireless interfaces would also be welcome in a traveling notebook. A good graphics subsystem might also come in handy so that the user could relax a little at some game.

You think it’s impossible? Not at all! The Dell Inspiron XPS M1201 is a vivid example of that. Depending on the configuration, this 12” cutie (it easily fits within the dimensions of the A4 paper format and thus into any briefcase or bag) can satisfy any person who is spending much of his life traveling. Appearances are often misleading, and a cursory glance over the Inspiron XPS M1210 won’t disclose to you the fact that this notebook has one of the most advanced of today’s mobile CPUs coupled with a rather powerful graphics subsystem. Not all notebooks marked as XPS M1210 have a discrete graphics solution on board, though. There is a version that has a tremendous computing power but is weak in 3D and gaming applications because it uses the integrated graphics core Graphics Media Accelerator 950.

It’s the latter version of the notebook that we’ve got for our tests. The Dell Inspiron XPS M1210 is based on a Merom-core CPU with the Core micro-architecture. The Merom differs from the previous core Yonah in a few respects. First, the Intel Core 2 Duo T7600 has a 4MB L2 cache. The execution pipeline is almost the same length in all CPUs with the Core architecture, yet it is longer by two stages in the Core 2 Duo. The most notable improvement is the support of Intel’s 64-bit extensions to the x86 architecture and the so-called Intel Wide Dynamic Execution that means that the CPU core now has more decoders and execution units. The processing of SSE and floating-point instructions has been accelerated. With all these innovations, the Merom core has a typical heat dissipation of 34W as opposed to the Yonah’s 31W. The rest of the components of the Napa platform are left unchanged and the CPU socket will remain the same until the upcoming transition to the Santa Rosa platform.

The stickers they put on the notebook case are the same too, except that the Intel Core 2 Duo Inside sticker now has the number 2 that stands for Merom. The Centrino Duo logo doesn’t allow telling which exactly CPU resides inside the notebook.

Our tests will show how such crucial parameters of notebooks as battery life and performance have been affected by the technical innovations. But first we’ll examine the Dell Inspiron XPS X1210 carefully from all the sides. We’ll also take an ASUS W5F notebook as an opponent to the Inspiron. The notebook from ASUS has a similar hardware configuration, but a different CPU with a different clock rate. The Inspiron XPS M1210 is based on a Merom-core processor with a frequency of 2.33GHz while the ASUS W5F has a Yonah-core 2.0GHz CPU (it is the highest CPU frequency among all the Intel Core Duo processors we’ve ever tested in our labs).

Design and Ergonomics

The first thing you become aware of in the Dell Inspiron XPS M1210 is its smooth outline. The front part is rounded off a little, giving the notebook a very neat appearance. The lid is coated with black plastic and has a silvery band with the name of the series near the display hinges. On the front panel there is a small chromium-plated ledge to make it easier for you to lift the lid up. The sides of the lid are by half painted silver to match the top part of the notebook’s body. The rest of the body is painted black.

The manufacturer put its logotype into the center of the lid.

Before opening the notebook, you can take note of the three connectors in its front part. One is a microphone input and the other two are identical headphones outputs. Not a very common solution, this allows enjoying the multimedia capabilities of the Inspiron XPS M1210 battery together with your friend while on a plane, for example.

Above those connectors there is a block of multimedia buttons highlighted in blue when the notebook is turned on. These buttons include (from left to right):

* Mute On/Off

* Volume Down

* Volume Up

* Play/Pause

* Previous Track

* Next Track

* Stop

We don’t think these buttons are really necessary for an ultra-compact model unless you are going to use it as a player. Due to the small size of the notebook, you will almost surely touch the multimedia buttons unintentionally with your wrists while you’re using the touchpad.

The display lacks a lock as is typical of notebooks of that form-factor. Mechanisms built into the hinges press the lid down to the notebook’s body, and you have to exert some strength to lift it up. The color scheme is all silvery inside, including the magnesium case, keyboard, touchpad, and the screen bezel. There are rubber pads on that bezel for softer contact between the display and the notebook’s body. Centered beneath the display is the Dell logotype.

The Dell Inspiron XPS M1210 may come with an optional 1.3-megapixel web-camera that can turn around by 180 degrees. It resembles the one installed on the ASUS W5F. Our notebook didn’t have that camera, though.

Besides the manufacturer’s logo, there are two sonorous stereo speakers on the bezel, below the display. They are covered with grids and are directed right at the user. This placement is good because the speakers won’t get obstructed with anything.

The display hinges stick out of the notebook’s body, allowing you to unfold it by even more than 180 degrees as is shown in the following photograph:

The Dell Inspiron XPS M1210 is equipped with a widescreen 12.1” display with a max resolution of 1280×800 pixels and an aspect ratio of 16:10 (WXGA). The horizontal viewing angle seems to be large, but the vertical one is narrow even visually. The glassy coating of the display makes colors more saturated (Dell TrueLife technology), but also produces flares under improper lighting and reflects every well-lit object behind your back.

We measured the brightness and contrast of the notebook’s display using a Pantone ColorVision Spyder with OptiCAL version 3.7.8 software. We selected the highest possible brightness setting before this test but it would become much lower when the notebook switched to its battery, automatically enabling power-saving measures. The measured values of brightness are high, but the contrast ratio isn’t:

AC power source:

* 110.1cd/sq.m brightness, 27:1 contrast ratio

DC power source:

* 90.9cd/sq.m brightness, 27:1 contrast ratio

The notebook’s keyboard consists of 84 silvery-colored keys with a soft movement and a somewhat rough surface. The Arrow keys are lowered below the keyboard’s baseline to reduce the risk of your pressing them unintentionally. The Fn button is located at the bottom left of the keyboard, next to the Ctrl key, which is in the corner. This is convenient for people who are used to shortcuts like Ctrl+C or Ctrl+V. Numeric buttons and two Windows keys are available: the Context Menu key is over one key on the left of the spacebar and the Windows Logo is on the right of the spacebar. The functional buttons are smaller than others. PgUp and PgDn are placed under the Enter. Home, End, Insert and Delete are in the same row with the functional buttons (you should press them along with Fn to access their additional functions). The letters are painted in black; the functional keys are blue.

Testbed and Methods

The notebook’s hard drive was formatted in NTFS before the tests. Then we installed Microsoft Windows XP Professional SP2 with DirectX 9.0c, system drivers (from the included disc), and Windows Media Encoder 9.0 with Windows Media Player 9.0. We also installed Windows Media Player 10.0 for such tests as PCMark 2005 and SYSMark 2004 SE.

The following settings were used for the tests:

* Power-saving services – Off

* Audio subsystem – Off

* Network services – Off

* Maximum screen brightness

* Maximum display resolution (1440×900)

* Windows Taskbar is Unlocked

* Windows Taskbar hides automatically

* Classic Desktop theme

* No background image on the Desktop

* No screensaver

* Low security level

* Pop-ups blocking disabled

There were two exceptions: we returned to the Windows XP desktop theme for PCMark 2005 since the program required that. And for SYSMark 2004 SE to work normally, we had to roll each parameter back to its default (as they are set right after you install Windows).

Two power modes were used. First, we selected the Always On power mode for maximum performance and the shortest battery life. Then we switched to the Max Battery mode for the maximum battery run-down time.

Our tests:

1. Performance benchmarks: synthetic (SiSoftware Sandra 2005, SiSoftware Sandra 2007, PCMark 2004 1.3.0, PCMark 2005 1.2.0), office and multimedia (SYSMark 2004 SE, Business Winstone 2004, Multimedia Content Creation Winstone 2004), and games (3DMark 2001SE Pro, 3DMark 2003 3.6.0, 3DMark 2005 1.2.0, 3DMark 2006 1.0.2, Quake 3, Quake 4, Unreal Tournament 2003)

2. Battery life tests (Battery Eater Pro 2.60)

There are three test modes in Battery Eater:

* Classic (the system is under a high and evenly distributed load)

* Reader’s test (the pages are browsed through each 15 seconds)

* Idle mode

We used the first two modes as they are in Battery Eater, but in the Idle mode (when the test utility doesn’t put any load of its own on the notebook) we played a DVD movie.

Conclusion

Michael Dell’s team has done a good job again, coming up with an exciting ultra-compact portable computer optimized for today’s life and travels. The only significant drawback in the configuration of the Dell Inspiron XPS M1210 that we tested is the lack of a discrete graphics card that would certainly make it even more appealing. Well, the model we actually tested is quite ready for the nomadic way of life many of us have to lead. We called the ASUS W5F with its Yonah-core CPU a mobile intellectual in our earlier review, but the Dell Inspiron XPS M1210, even with its integrated graphics, is much smarter without a doubt!

This year will show us the Merom from other aspects, too. This CPU core is going to have higher frequencies and to work within the framework of the Santa Rosa platform together with an improved integrated graphics core. This sounds to us like yet another performance leap!

Highs:

* Superb ultramodern design

* Excellent performance in office applications (and not limited to them if the configuration includes a discrete graphics card)

* Abundance of wireless interfaces (including support for SIM cards)

* Exclusive TrueLife technology for better image quality

* Appealing and competitive price

* High-resolution widescreen display

* Relatively long battery life

Lows:

* Mirror-like display

* Low performance in games

* Inconvenient placement of the multimedia buttons

* Optical combo-drive

* Rather too noisy

* Dense placement of USB ports (but it’s good that there are as many as four of them here!)

A laptop is the ideal replacement for your desktop computer. The greatest advantage of a laptop is its portability. Unlike desktop computers, you can easily move a laptop around your home, carry it to work or class and take it with you when you travel. Laptops are a big investment, so before buying one, you should consider many factors like the manufacturer, performance and features.

What kind of laptop user are you?

A home user wants all the features of a desktop PC in the form of a notebook. If you are a home user, then choose a notebook which is easy to carry and comes with the most basic computer applications. Students should opt for an affordable laptop which is light and durable. Frequent fliers need slim notebook models with long-lasting batteries. A business user should purchase a laptop with plenty of hard disk space and advanced security features while a gamer needs a fast processor and the latest graphics card.

What are the different kinds of laptop computers available?

Laptops for Entertainment:

Multimedia laptops are always more expensive and heavier than your standard model. These laptops come with a powerful processor, abundant memory and a large hard drive. You can use these laptops as a mobile DVD player, MP3 jukebox and a digital photo album. If you buy a TV tuner card, you can even use your multimedia notebook as a television set. These notebooks are ideal for PC gaming.

Laptops for Business:

Laptops especially designed for business use are ultra portable. These laptops are durable and more secure than the basic laptop. They are best suited for consumers who are always on the move. A good business laptop should offer a fingerprint reader or SmartCard support to prevent data theft. These notebooks usually have advanced computer applications and wireless capabilities, so you can work even when you are away from your desk.

Laptops for Home:

The home user typically uses a laptop for checking mail and browsing the web. These laptops perform general tasks. A high speed processor is an unnecessary luxury and tends to be wasted on most home users. Opt for a notebook with at least a 14-inch screen and a comfortable keyboard. These laptops are generally heavy, weighing more than 4 kg at times. Their average battery life is less than three hours.

What constitutes a good laptop?

Ergonomics:

If you are going to use your laptop extensively, then you need to be comfortable with the keys. Try a laptop with slightly larger keys to avoid straining your fingers from typing. Most laptops come with a touch pad or a tracking pointer instead of a mouse. If you are a PC gamer, buy a separate mouse which can keep up with the fast-paced action on screen.

Operating Systems:

The Windows XP Media Center Edition is a good operating system for entertainment laptops. It makes optimal use of multimedia features like TV tuners, radio tuners and media players. If you are a professional who prefers Apple notebooks but are concerned about compatibility, check out the dual boot models by Apple that allow you to install and run Windows as well as Mac OS X. If you prefer PCs, Microsoft Vista is an ideal alternative to Windows XP. Vista comes in several editions, including Vista Home Basic and Vista Home Premium for the home user, Vista Business for the professional and Vista Ultimate for the best of both worlds.

Memory and Storage:

All data and applications are stored in the RAM (random access memory). Many laptops commonly use 256 MB of RAM. Most business laptops and entertainment laptops come with 512 MB or more of RAM. The more RAM you buy, the more data you can store.

The hard drive stores all programs and files. For the average home user, a 20 GB hard drive will more than suffice. If you buy a laptop for entertainment or business purposes, a 60 GB hard drive will better serve your needs. Some entertainment laptops even have multiple hard drives for better performance. Hard drives come with different speeds. Most laptop hard drives have a speed of 5,400 rpm. However, faster hard drives go up to 7,200 rpm.

Display:

The size of a laptop is based on the size of the screen. Screen size starts as small as 10.6 inches and goes up to 20 inches diagonally. Most laptops have an LCD monitor. However, if you are using your laptop for CAD, a CRT monitor will serve you just as well, if not better. The screen resolution determines the crispness of your image. A 12.1 inch display uses WXGA resolutions (1,280 by 800). A 14 or 15 inch display typically uses WSXGA+ (1680 by 1,050), although a small number of notebook computers use WUXGA (1,920 by 1,200) instead.

Processor:

It is more difficult to upgrade a notebooks processor than it is to upgrade a desktop computer. For this reason, you should buy a processor with a speed that will best suit your use. Also, it is wise to choose a processor with less battery consumption. Processors with 1.4 to 1.6 Ghz are preferred by most users.

Battery:

Lithium ion batteries are commonly used in laptops. The average battery life is about 3 hours. It takes around 75 minutes to fully recharge a lithium ion battery.

Graphics Card:

A graphics card, sometimes referred to as a video adapter, is responsible for generating the images you see on a laptops display. For businessmen who need to do lot of presentations, a graphics card containing 32 or 64 MB of dedicated memory is the right choice. There are also specially designed cards for gaming. These cards are expensive and should be avoided unless you require excellent graphics.

USB Ports:

Laptop computers come with at least one USB port so that you can connect peripherals to the notebook. Recent models have a FireWire connection that lets you transfer digital information from camcorders or MP3 players.

Optical Drives:

Most laptops come with either a CD-ROM (compact disc, read-only memory), a CD-RW (compact disc, re-writeable) or a DVD-ROM (digital versatile disc, read-only-memory). The DVD+RW/+R with CD-RW is a combination drive which will read a CD or a DVD and write data to a DVD as well.

Modem:

Laptops are available with integrated modems for dial-up connections, Ethernet ports for cable internet and DSL and wireless modems for Wi-Fi connections. Many business laptops also have a cellular wireless modem so you can browse at broadband speeds with just a mobile phone signal.
