If you want to change the default settings for a scheme, click the drop-down menu in the Turn off
monitor, Turn off hard disks, System stand by, or System hibernates field, and then select a time-
out from the displayed list. Changing the time-out for a scheme field permanently changes the
default settings for that scheme, unless you click Save As and enter a new name for the changed
scheme.
NOTICE:
If you set the hard drive (hard disk) to time-out before the monitor does, your computer may
appear to be locked up. To recover, press any key on the keyboard or click the mouse. To avoid this
problem, always set the monitor to time-out before the hard drive.

computer.
To program these functions, click an option from the corresponding drop-down menu and
click OK.
