There is a feature on many macs to restart after being switched on (designed as a failsafe if they were used as servers).
Taken from the mac FAQ: http://macfaq.org 2.5.12 - Why does my Mac keep restarting when I shut down? The Mac IIsi, IIcx/ci, IIvx/vi, Performa 600, Quadra 700, Centris/Quadra 650, and Power Mac 7100 had a rather nice feature designed for ease of use as servers: the power button can be locked in the in position so that when the power is interrupted, the Mac will restart automatically. To disable this feature (rather annoying if you don't want the computer running 24/7), simply take a flathead screwdriver and turn the power button in the back about a quarter-turn in either direction. The button will pop out and the Mac will no longer restart whenever it's shut down. If you don't have one of the Macs with this power supply, try a different keyboard, mouse, and keyboard cable. Defective ADB devices can cause these symptoms as well. If trying a known-good keyboard, mouse, and cable doesn't fix it, then you likely have some sort of power supply problem and probably should replace your power supply. If that doesn't fix it, a logic board problem is likely, particularly in the startup circuitry. I had a similar problem with my quadra 800 a while ago. Hope it is this problem, as it's pretty easy to solve! :-> Ian > Message-ID: <000501c21207$0d1bec40$66169fd4@arochester> > From: "Alan Rochester" <[EMAIL PROTECTED]> > Subject: Seems to switch itself on! > Date: Wed, 12 Jun 2002 12:45:52 +0100 > > I have recently been given a Performa 630 DOS Compatible machine running OS > 8.5. > > I have switched it off by the keyboard, by the Special menu and by > AppleScript.
