CAUTION
Make a habit of saving your work before allowing your computer to enter Standby
mode. If power is interrupted while the computer is in Standby mode, any
information that was not saved will be lost.
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 56.) 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 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 XP: click Start, Control Panel, Performance and Maintenance, Power
Options.
 
Windows 2000: click Start, Settings, Control Panel, and then double-click 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
To conserve battery power, the computer automatically runs the processor at a slower
speed when the AC adapter is unplugged. To run with maximum performance, plug in the
AC adapter. For Windows XP, you can control the processor speed and power in Control
Panel Power Options—on the Power Schemes tab, select the power scheme you want.
