Hi Bruce,

At the end of the "hibernation" process, the PC is powered off and you can unplug
the AC power cable of your desktop computer or remove the battery/power supply
in case you are using a notebook.

In the help file of Windows 98SE you can read:

You cannot put your computer in hibernation if you have a FAT32 drive.

Do you see the BIOS perform the typical power on self test when you resume
from hibernation?

Best regards,

Luciano
