An often overlooked feature of Windows is its ability to alter the power settings of the computer. In Windows Vista, selecting an adequate power scheme is very easy.

Look for a tray icon that looks like a battery, or a plug if you’re plugged in. Left click it once, and a power plan selection should appear as pictured to the right.

For maximum performance, select the ‘High performance’ power plan.

If you have Windows XP, you can click the battery and a menu will appear where you can select Maximum performance to achieve the same effect.

Note that selecting a higher performance mode will use more power when on battery only, thus reducing the time you have between charges.
