vThe system status, RAM, VRAM, and setup data are stored on the hard disk.

vThe system is powered off.

Notes:

The computer cannot enter hibernation mode when it is powered with ac power and a communication PC Card is used.

Any one of the following events causes the computer to enter hibernation mode when the hibernation file is created:

vThe Fn + F12 keys are pressed.

vThe power switch is turned off and the mode is set to Power switch mode [Hibernation].

vThe timer conditions are satisfied in suspend mode (for operating systems other than Windows 98).

vA critically low battery condition occurs.

When the power is turned on, the computer leaves 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.
