The Standby Timeout field in System Setup enables you to specify
the time period that the computer can remain idle (no user input

can disable this option by selecting Off, or you can specify a

controller slow down. The LCD backlight, hard drive, floppy

If you enable both standby and rest modes, your computer
enters standby when the delay time you chose for standby has
elapsed, and then enters rest mode when the delay time you
chose for rest mode has elapsed.
