Power Management for Windows 98
Rebooting After a Lockup
Occasionally you may encounter a frozen keyboard or a locked screen. To
reboot your computer (as if from a cold start), press and hold down the Power
Button for at least four seconds, which will cause a manual shutdown. Then,
restart the computer with a single press of the Power Button. If it still does
not recover, press the
Power Button and hold it for four seconds to power off the computer. Then,
remove the battery or unplug the AC power for at least 30 seconds. Reinsert
the battery or reconnect AC power and press the Power Button once to
reboot.
