Batteries and Power Management

Managing Power Consumption

The notebook can also enter Hibernation if battery power reaches a critically low level. 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, and then shut the notebook off and restart it.

	Changing timeout settings and creating power schemes
	You can adjust the periods of non-use after which your notebook automatically shuts
	down components or enters a power-saving mode. You can also save these settings
	as a power scheme.
	1. Select Start > Control Panel > Performance and Maintenance > Power Options.
	2. Select 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, select 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 notebook battery runs down completely.
