Are you having problems with the battery life on your laptop? Do you know if you have Windows optimally configured to provide the best power consumption?

There are a number of different options which you can set including the sleep timer, screen saver, display brightness, power plan, wireless adapter settings and the minimum processor state which all contribute to a longer battery life when configured correctly.

Microsoft have released an Automated Troubleshooting Services Fix It package which automatically detects these settings for you in Windows Vista and sets them to optimum values to conserve your laptop battery life.

Ever run out of battery power in the middle of an important meeting or a long flight? Even with advances in technology, your laptop battery can last only so long on a single charge. The trick is to squeeze the most out of the power that’s available.

Chances are, you already have ways to make sure your laptop always has power. Maybe you carry an extra battery, or your power cord, so you can recharge your laptop when a power plug is handy. (Always consult your manufacturer’s instructions for the best way to recharge your battery.)

When those strategies fail, here are some other ways to help stretch your computer’s battery life.

hoose a power plan that saves power

A power plan is a collection of hardware and system settings that control how your laptop manages power. Windows 7 has two default plans:

Balanced. Offers full performance and display brightness when you need it, but conserves power when the computer is idle.
Power saver. The best choice for extending battery life. The cost? Slower performance and lower display brightness.

Your computer manufacturer might offer additional plans.

Reduce display brightness

The display can use more power than any other part of a computer—even more than a hard disk and CPU. Some laptops have a dedicated button or dial to change the display brightness. To find out if your laptop has something like this, check the information that came with your computer or go to the manufacturer’s website. You can also adjust the display brightness from Power Options in Control Panel.

Shorten the length of time before Windows dims and turns off the display

When you’re not using the laptop—even for brief periods of time—you can save power by having Windows dim and then turn off the display after a period of inactivity.

Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.
On the Select a power plan page, on the left, click Choose when to turn off the display.

Note

Doing this adjusts settings only for the plan that you’re currently using. To change settings for another plan, click Change plan settings next to the plan that you want to change.
On the Change settings for the plan page, choose the display settings that you want to use for this power plan when your laptop is running on battery and when it’s plugged in.
Click Save changes.

Turn off or remove devices that you aren’t using

Many USB devices use power just by being connected. If you use a USB mouse, you can save power by disconnecting the mouse and by using a touch pad or tablet pen. If you use a USB flash drive, unplug it when you’re not using it.

Turn off PC cards and integrated wireless devices

These devices also use power. If you don’t need them, turn them off.
