press the power button for less than four seconds.
Notes:
To use this combination of the keys, ThinkPad PM device driver
must have been installed on the computer.
Though the screen fades out immediately after Fn+F12 are pressed,
the computer does not enter the hibernation mode immediately. Do
not move the system until the sleep (standby) status indicator stops
blinking. Moving the computer when it is entering hibernation
might cause corruption of the hard disk drive.
