Save-to-disk, Suspend Mode

Page 15 highlights

The Save-to-disk option under Suspend Mode copies all system data to a reserved area on the hard-disk drive and then turns off all power to the computer. When you resume normal operation, the same programs will be running and the same files will be open that were loaded before you activated this mode. Use Save-to-disk suspend mode to conserve battery power or to preserve system data by quickly saving it to the hard-disk drive if you are about to run out of battery power.

System Overview

The
Save-to-disk
option under
Suspend Mode
copies all system data to a
reserved area on the hard-disk drive and then turns off all power to the com-
puter. When you resume normal operation, the same programs will be running
and the same files will be open that were loaded before you activated this
mode. Use
Save-to-disk
suspend mode to conserve battery power or to pre-
serve system data by quickly saving it to the hard-disk drive if you are about to
run out of battery power.
