Events that cause entering of hibernation mode:
The hibernation mode is requested by the Fn key
(Fn+F12).
Timer conditions are satisfied in suspend mode.
Critical low battery condition. The system first goes
into safe suspend mode, then when the battery
reaches critical the system goes into the hibernation
mode.
Event that causes exiting of hibernation mode.
The power-on switch is operated.
When power is turned on, the hibernation history of the
boot record on the hard disk is recognized and system
status is restored from the hard disk to resume operation.
Doze Mode: In the Doze mode, the system slows
down the central processing unit and the system uses less
power. Enable the doze mode in the setup program.
Exiting the doze mode is instantaneous by pressing any
keyboard key.
Safe Suspend: Saves the computer state, then
enters the suspend mode.
Port Replicator Power Overload: If power shut
downs occur intermittently when using a port replicator,
suspect an over-current problem. Some devices use more
power; if the maximum usage of each device occurs
simultaneously, the total current will exceed the limit,
thereby causing a power shut down. Isolate this problem
by removing one of the devices, and use the computer
under the same condition to see whether a power shut
down occurs. Do this procedure for all devices, then
determine the cause.
Setup Utility
Note
The Setup Utility is ROM-resident and can only be
started at a full-screen DOS prompt.
Do the following to run the Setup Utility.
1. Go to a DOS full screen.
2. Press Ctrl+Alt+F11.
3. Follow the instructions on the screen.
Note
When exiting the Setup Utility using Fn+6, press
Ctrl+Alt together after returning to the full-screen
DOS. This ensure the keyboard controller is in the
proper reset state.
