How to treat your battery right

For on-the-go computing, your battery is your best friend. Knowing how it likes to be treated is the first step to keeping both of you happy.

• Keep battery contacts clean. Battery contacts can get dirty or corroded over time, reducing the effective delivery of power. With your mobile PC turned off and unplugged from its external power source, remove the battery. Use a cotton swab dampened with rubbing alcohol to wipe the metal contacts on the battery and inside the device. Allow them to dry completely before reinstalling the battery and reconnecting to a power source. Repeat this procedure every two to three months.

• Charge your battery correctly. When you're on the road, be sure to carry a power cord and plug your computer in whenever you have the chance. Unlike the older-generation rechargeable batteries like nickel-based (NiMH) batteries (see next paragraph), modern lithium ion batteries can be partially discharged and recharged repeatedly with no harmful effects, but you should avoid fully discharging lithium ion batteries. Consult your owner’s manual for more specific tips on charging, and never use an AC adapter (power cord) or battery charger not approved by your device’s manufacturer.

• Completely drain nickel-based batteries periodically. If you're using an older laptop (at least three years old) with a nickel-metal hydride (NiMH) battery, be sure to completely drain it and recharge it (every one to three months—consult your owner’s manual) to ensure that it will hold a full charge. (Most newer mobile PCs use lithium ion batteries, which don't need to be drained to maximize their capacity.) To drain a NiMH battery, simply turn on your computer, unplug it from its external power source, and let the computer run. To speed things up, you could start several applications, turn the screen brightness to its highest level, and ignore all of the great power-saving strategies below. After the power is completely drained, recharge the battery fully. This may take up to 12 hours.

• Cool it. Your mobile computer generates heat, and higher operating temperatures reduce your device’s efficiency, which in turn demands more battery power and can shorten battery life. Make sure that your computer can “breathe”: Don’t let clothing, lint, or other obstructions block the cooling vents. See How to clean your computer for more tips on keeping your computer spotless and running smoothly.

• Carry a spare. Buying an extra battery is a good investment for your peace of mind. Battery prices vary widely. You can significantly increase the power available to you if you're willing to splurge a little. Contact the manufacturer of your mobile PC to find a replacement battery, or find here.

• Store it properly. If you don’t expect to use your mobile computer for a week or more, it’s a good idea to store the battery, discharged to about 40 percent of full capacity, in a cool place. Click the battery status icon in the notification area of the Windows taskbar to check the current charge. Avoid storing a fully discharged—or fully charged—lithium ion battery for extended periods, as this can diminish battery life.

questions & answers： about laptop battery

Question:
How long a laptop battery should last after each charge?

Answer:
After the laptop has gone through a full single charge and the power plug is unplugged the average life of a laptop battery can be anywhere between one and six hours. This time is dependent on the battery, its capacity (mAH), what's being done on the laptop, and how old the battery is. Over time the laptop battery total capacity decreases, which means the battery will not last as long as it did when you first got the laptop and will continue to decrease over time.

Defragmenting your laptop：Why & How?

Over time and with regular use, files and folders on a computer's hard drive break down or become fragmented. When computer files are fragmented, they are typically disorganized and in the wrong place. This can cause the system to run slowly and to experience processing problems. Defragmenting the computer gathers and organizes the files, which usually improves retrieval time and the computer's overall performance.

For example, a computer program must access various files on the hard drive every time it is run. If those files are spread out on opposite sides of the hard drive instead of gathered and organized neatly, as they are supposed to be, the computer will have to work extra hard and take extra time to access the information it needs. In some cases, severe defragmenting may even cause a program to stop running entirely.

Defragmenting, also referred to as "defragging," reorganizes the hard drive by putting pieces of related data back together so that files are organized in a contiguous fashion. As a result, the computer system can access files more efficiently. By efficiently organizing files and folders, defragmenting will leave the computer's free space in one big chunk. This will allow new files to be saved in an orderly fashion, thereby reducing the need for future defragmentation.


What's the Benefits of Defragging

As the overall size of disk drives keeps increasing, defragmenting a computer regularly may even help to increase its life-span. A system needs to work quite hard in order to collect fragmented information across larger and larger disks. Considering the amount of work this takes, it seems likely that defragmenting can help a hard drive last significantly longer.

Though some computer experts argue that today's operating systems are efficient enough to eliminate the need for defragmenting altogether, it is generally recommended that computer users defrag their systems on a regular basis. Average users will probably find that bimonthly defragmenting produces sufficient results. Users who notice a frequent loss of efficiency and speed may choose to defrag more often.

It's sure that defragging your laptop daily with extend laptop battery life


How to Defragment

All computer systems come with some type of defragmenter tool, commonly found under the "System Tools" option in Windows-based PC environments. Such tools typically come with an analysis feature that will actually tell users if their computers need defragging or not. You can also defragment disks from a "C prompt" command line using the "defrag" command. Additional information on how to defragment a computer should also be available on the Internet.

Optimise Your Power Settings to Increase Laptop Battery Life

Modern laptops are much better at conserving their power than older computers. Many are equipped with green hard drives or even solid state drives designed to minimize power consumption and most laptops have special green settings that cut down on power usage while extending laptop battery life.

Even so, laptop computer users can often extend the battery life of laptops by changing a few key settings. Here's a quick guide to ecologically friendly laptop batteries power settings that can extend battery life significantly.


Laptop Settings In Windows

Laptops that use Windows 7*, XP* or Vista* have a few predetermined power plans for users to choose from as well as a Custom option. To view these plans, open Control Panel from your computer's Start menu. Choose Power Options from either the System and Maintenance (Windows 7 and Vista) or Performance and Maintenance (XP) menus.

The Power Options menu offers both simple and advanced settings. Some laptops have a special eco-friendly plan which limits screen brightness while lowering the time it takes for a computer to go to sleep or hibernate. Choosing custom options will allow you to choose each setting separately, so sleep and hibernate times can be manually set.

To get really great laptop battery life, laptop users should lower their screen brightness through the Display menu in the Control Panel. Some laptops also have special graphics card programs which can be used to minimize power consumption while a computer's unplugged.


Mac OS* Laptops

Apple laptops have similar power settings, although changing them is a bit different. Go to your computer's Apple menu and select System Preferences. The Hardware tab has several power-related settings that can be changed by computer users. Sleep settings can be changed under the Energy Saver tab. Processor performance can also be changed. Lower processor speeds mean a slower computer, but can also mean better battery life.

With all modern laptops, it's a good idea to set power settings as soon as possible after buying a computer. When a computer is unplugged, running down its battery completely before recharging may extend battery life. Check your computer's manual to find out if this is the case.

Making these simple adjustments to a laptop's power settings is a great way to keep a battery running for longer and to reduce your power bill. With a slightly dimmer screen and manually adjusted sleep settings, a computer can often get 20 percent or more battery life. It's well worth the time to make a few key adjustments, especially if you frequently use your laptop on battery power.
