Managing Power Consumption

The computer can also enter Hibernate mode if battery power reaches a critically low level. (See “To respond to a low-battery warning” on page 54.) If this happens, you will find on resuming that all your data has been saved, but some functions may be disabled. To resume normal operation, restore power by connecting an AC adapter or installing a charged battery, then shut the computer off and restart it.

	Changing timeout settings and creating power schemes
	You can adjust the periods of non-use after which your computer automatically shuts
	down components or enters a power-saving mode. You can also save these settings as a
	power scheme.
	1.	Open Power Options in Control Panel:
		∙ Windows 2000: click Start, Settings, Control Panel, then double-click Power
		Options.
		∙ Windows XP: click Start, Control Panel, Performance and Maintenance, Power
		Options.
	2.	Click the Power Schemes tab, and enter the settings you want. If you don’t want a
		particular timeout to occur, set the value to Never. See Windows Help for details.
		If you want to save the settings as a power scheme, click Save As and enter a name
		for the scheme.
CAUTION	Do not disable Hibernate support in the Power settings, or you will lose any
	unsaved data if the computer’s battery runs down completely.
	Managing CPU power
	If your computer contains a multispeed processor with Intel SpeedStep Technology, the
	taskbar in Windows 2000 contains an Intel SpeedStep Technology icon. This feature
	enables the processor to automatically switch to lower, power-saving speeds or to higher-
	performance speeds according to the workload.
	You can customize SpeedStep to best suit your working environment.
	∙	Windows 2000: Double-click the Intel SpeedStep Technology icon in the taskbar,
		then select the battery and AC options you want. The Max Battery option uses the

lowest processor speeds for maximum battery time. The Auto option uses medium and high processor speeds.
