On IBM ThinkPads (which do refer to it as hibernation in the manual)
hibernation is enabled by running the supplied DOS utility (or the Windows
GUI thing) to create a "hibernation file" on one of the FAT partitions on
your disk. Then pressing the key combination Fn+F12 initiates hibernation
(whereas Fn+F4 or just closing the lid initiates a suspend). As far as I
can make out, the OS cannot see any difference between hibernation and
just suspending the machine, and it works pretty well (now all the minor
irritations have been sorted out, like compiling the floppy as a module -
why it should need that I have no idea!).
There are also several options which you can set in the DOS or Windows
utilities [there is also one for OS/2 of course], including:
- hibernate when you press the power key instead of switching off.
- hibernate automatically 30, 60 or 90 minutes after you suspend.
- "Readisafe" mode, which means that when you suspend it will save to disk
just in case the battery runs out. Normally when you come back to the
machine it will resume from the suspend in a couple of seconds as usual.
But if it ran out of power you just switch it on and it reads the state
back in from disk just as if you had hibernated it.
