Hibernation mode
In hibernation mode, the following occurs:
• The system status, RAM, VRAM, and setup data are stored on the hard disk.
• The system is powered off.
Note: If the computer enters the hibernation mode while it is docked to the docking station, do not undock it
before resuming normal operation. If you do undock it and then try to resume normal operation, you will get
an error message, and you will have to restart the system.
To cause the computer to enter hibernation mode, do any of the following:
• Press the Fn+F12 keys.
• If you have defined one of the following actions as the event that causes the system to go into hibernation
mode, perform that action.
– Closing the lid.
– Pressing the power button.
– Pressing Fn+F4 keys.
Also, the computer goes into hibernation mode automatically in either of the following conditions:
• If a “hibernation time” has been set on the timer, and if the user does not do any operation with the
keyboard, the TrackPoint, the hard disk drive, the parallel connector, or the diskette drive within that time.
• If the timer conditions are satisfied in suspend mode.
When the power is turned on, the computer returns from hibernation mode and resumes operation. The
hibernation file in the boot record on the hard disk drive is read, and system status is restored from the
hard disk drive.
