functions to save power when you use the battery pack or the AC
Adapter:
Operation modes. The operation modes control the processor
speed or set timers for saving power. For more information
about the operation modes, see

on page 30.
Power-saving modes.
Standby mode. You can enter standby mode for short idle
times, such as when you are having a short conversation.
Suspend mode. You can enter suspend mode for somewhat
longer times when you are away from your computer.
Hibernation mode. You can enter hibernation mode when you
leave your office for the day.
It takes more time to return to normal operation from suspend mode
than to return from standby mode, but the computer does not use as
much power.
