IBM X23 - Manual (Page 34)

v The resume timer is set. In Windows 98, the Scheduled
Tasks setting has priority over the Resume on timer
selection in the “Power Management Properties”
window.
Note: The computer does not accept any input
immediately after it enters suspend mode. Wait a
few seconds before taking any action to reenter
operation mode.
Hibernation mode
Note for Windows NT
A Windows NT user cannot create a hibernation file
in a Windows NT system that uses NTFS format,
the Windows NT default format. If you want to use
hibernation mode, you will need to reinstall Windows
NT with FAT format.
In hibernation mode, the following occurs:
v The system status, RAM, VRAM, and setup data are
stored on the hard disk.
v The system is powered off.
Notes:
1. In the ThinkPad Configuration program, the
computer can be set to suspend/hibernate
while docked.
2. The computer cannot enter hibernation mode
when it is powered with AC power and a
communication PC Card is used.
3. If the computer enters the hibernation mode
when it is docked to the docking station, do not
undock it from the docking station before
resuming normal operation. If you do undock it,
then if you try to resume normal operation, you
will get an error message, and you will have to
restart the system.
Any one of the following events causes the computer to
enter hibernation mode:
v The Fn + F12 keys are pressed.
v The power switch is turned off and the mode is set to
Power switch mode Hibernation.
v The timer conditions are satisfied in suspend mode (for
operating systems other than Windows 98).
