Try removing the keyboard after shutdown and see if it restarts. If it still restarts remove the logic board, plastic casing and top metal cover and glance in at the power supply. Many built by Astec for Apple overheat badly, and component failure here can cause them to start on their own. If likely defective it will have a charred area in its centre, close to a small transformer with a yellow bobbin. The 630 (is it a 630, that�s a 68040 based system that can run only up to OS 8.1, you have 8.5) doesn't have a power switch that can be pushed and turned to lock in the on position.
