Hibernation Mode
In Hibernation mode, all power shuts off (the computer does not consume
any power). The computer saves all system information onto the hard disk
before it enters Hibernation mode. Once you turn on the power, the computer
restores this information and resumes where you left off upon leaving
Hibernation mode.
There are two necessary conditions for the computer to enter Hibernation
mode:
❑
The Hibernation file created by Sleep Manager must be present and
valid.
❑
Heuristic Power Management Mode must be set to [ENABLED].
In this situation, there are four ways to enter Hibernation mode:
❑ Pressing the Hibernation hot key Fn-F4
❑
If the waiting time determined by the computer’s power management
system elapses without any system activity
❑
If a battery low condition occurs and the Battery Low Suspend parameter
in Setup is set to [ENABLED].
❑
Invoked by the operating system power saving modes
❑ To exit Hibernation mode, press the power switch. The computer also
resumes from Hibernation mode if the resume timer is set and matched.
