Heuristic Power Management

User’s Guide
Experience an incoming PC card modem event
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 PhDISK must be present
and valid.
See “PhDISK” on page 73.
Heuristic Power Management 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 HPM
unit 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
Note:
If the computer beeps but does not enter
Hibernation mode after pressing the Hibernation hot key,
it means the operating system will not allow the computer
to enter the power-saving mode.
