1. Select Start > Control Panel > Performance and
Maintenance > Power Options.
2. Select the Power Schemes tab, then enter the settings you
want. If you do not 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 Options
settings or you will lose all unsaved data if the battery pack becomes
completely depleted.
