Using Windows Power Options
Windows Power Management provides basic power saving features. In the Windows
Power Options Properties [Start > Settings > Control Panel > Power Options] dialogue
box, you may enter time-out values for the display and hard disk drive. Windows Power
Manager saves power by turning off the hard drive after 1 minute of inactivity, for
example.
Windows’ Power Schemes
The power management control panel in Windows XP, known as Power Schemes, is
designed to provide the user with an easy-to-use interface. The Power Schemes tab
can be found in the Power Options Properties panel that is accessible via the control
panel window.
Schemes are easy to understand, based on notebook usage scenarios, and control not
only processor power usage but other system peripherals as well.
Go to [Start > Settings > Control Panel] and double-click the Power Options icon.
Always On mode puts the processor into maximum performance mode, which
provides no power saving. The other schemes control processor performance based on
demand. For example, Max Battery mode lowers the processor’s speed and voltage to
conserve power as much as possible.
