Chapter 15. Managing Hardware > Controlling Power Options

Controlling Power Options

You can change power options properties for a portable or laptop computer to reduce power consumption and maximize battery life. For example, if you often leave your computer for a short time while working, you can set your computer to go into standby, a state in which your monitor and hard disks turn off after being idle for a set time. If you are often away from your computer for an extended time, you can set it to go into hibernation, a state in which your computer first saves everything in memory on your hard disk and then shuts down. To help you set power options, you can choose one of the power schemes included with Windows or modify one to suit your needs. A power scheme is a predefined collection of power usage settings. You can also set alarms and passwords and show the power icon on the taskbar. The power options you see vary depending on your computer's hardware configuration. Windows detects what is available on your computer and shows you only the options that you can control.

Select or Create a Power Scheme

Click the Start button, and then click Control Panel.

Double-click the Power Options icon in Classic view.

Click the Power Schemes Tab.

Click the Power Schemes list arrow, and then select a power scheme.

If you want, modify the power scheme settings.

Click Save As, type a name for the new scheme, and then click OK.

Click OK.
