Low power mode work in the following way:
In Global Standby mode, the CPU clock stops and
several system devices enter lower power mode.
In Power-On-Suspend mode, more system
devices enter lower power mode. The
power/suspend indicator ( ) lights amber in
Power-On-Suspend mode. To end Power-On-
Suspend mode, you need to press a key.
When Suspend-to-Disk takes effect, the system
saves the current status to a "Suspend-to-disk
partition” on the hard disk. The computer then
turns off automatically. When you next turn on the
computer, it retrieves the status from the suspend-
to-disk partition, so that your computer is returned to
exactly where you were at the time of suspension.
Suspend-to-Disk is convenient in the sense that you
do not have to close all the software applications
before turning off, and, when you next turn on the
computer, the software applications are ready for
use in a matter of seconds.
1. Whenever the computer is turned on, it checks the suspend-to-disk
partition. If the partition does not exist and there is enough hard disk
space left, the computer automatically creates the partition.
2. If there is no suspend-to-disk partition, you can not use the Suspend-to-
Disk function.
3. You can verify the suspend-to-disk partition using the SCU program. (See
the "Utility Menu” section in Chapter 5.)
