Sleep Mode limitations
Sleep Mode will not function under the following conditions:
■ Power is turned back on immediately after shutting down.
■ Memory circuits are exposed to static electricity or electrical noise.
Hibernation Mode
The hibernation feature saves the contents of memory to the hard disk
when the computer is turned off. The next time the computer is turned on,
the previous state is restored. The hibernation feature does not save the
status of peripheral devices.
Benefits of Hibernation Mode
The Hibernation Mode feature provides the following benefits:
■ Saves data to the hard disk when the computer automatically shuts
down because of a low battery.
■ You can return to your previous working environment immediately when
you turn on the computer.
■ Saves power by shutting down the system when the computer receives
no input or hardware access for the duration set by the System
hibernate feature.
■ You can use the panel power off feature.
■ When the computer is shut down in Sleep Mode, the power indicator
flashes orange.
■ If you are operating the computer on battery power, you can lengthen
the operating time by turning it off into Hibernation Mode, as Sleep
Mode consumes more power.
■ Save your data. While entering Hibernation Mode, the computer saves
the contents of memory to the HDD. However, for safety sake, it is best
to save your data manually.
■ Data will be lost if you remove the battery or disconnect the AC adaptor
before the save is completed. Wait for the disk indicator to go out.
■ Do not install or remove a memory module while the computer is in
Hibernation Mode. Data will be lost.
