Suspend-Resume

4

The Power Management software introduces a new timesaving feature, Suspend-Resume.

The traditional process of powering off your system can be time consuming. Similarly, the process of rebooting and setting up your workspace also can take awhile. With the Suspend-Resume feature, you can power off your system quickly saving all your current work in process, and at the next power on return quickly to your workspace as it was when you left it.

You can leave your system suspended and powered off for an indefinite length of time without any data loss.

You can initiate Suspend by using the AutoShutdown feature in the Power Management software, or initiate it manually using the instructions in the next section.

Suspend allows you to do the following without loosing state:

Move your system from one location to another
Power off your system to conserve energy
Switch the system power source form a battery to the wall outlet (AC power supply) or vice-versa.

Note - Do not use the Suspend feature if you need to reconfigure your system. You must halt the operating system whenever you want to reconfigure your system.

Before suspending your system, you must wait for the following operations to finish:

Audio activity
Floppy disk activity
Tape activity
ISDN activity
Synchronous tty activity
