Managing Power Consumption

To use manual power management
You can shut down your computer manually whenever you need to with any of the
following three levels of shutdown.
System standby
Action
Turns off the display and hard disk drive.
When
Press the blue standby button.
Resume
Press the blue standby button to return to
your current session.
System standby can also occur automatically when the timeout setting in the Power
Management Properties window is reached. (In Windows 98 and Windows 2000, standby
and suspend are equivalent terms.)
Hibernate
Action
Saves the current session to disk, then
shuts down. Provides maximum power
savings while still allowing you to recover
the current session.
When
Press Fn+F12.
Resume
Slide the power switch to the left to recover
your current session. This takes several
seconds.
Hibernate can also occur automatically when:
• Battery power reaches a critically low level; see “To respond to a low-battery
warning” on page 51.
• In Windows 98, the timeout setting in the BIOS Setup utility is reached; the default is
two hours after System standby occurs. (In Windows 2000, the BIOS timeout setting
is ignored.)
