Dear All,
I have a Mac Performa 630 that does not stay shut down.
When I ask him to shut downd, it does but immediately it turns on again.
The same if I press the on/off button.
Can somebody help me to find where is the issue...?
Thank you

Are you positive the power button on the back is not stuck pushed in?
Secondly, have you performed any capacitor maintenenace yet? That would totally do that if the PMU was freaking out.

I once had a PowerMac 7100/80 doing the same. Never found out why. PSU was good, it was recapped etc.

The first answer sounded fairly good... the second not so much! :)
I will anyway check what's inside, expecially if the battery has done any damage.
I keep you info. Any other suggestions (for example some special config somewhere) are welcome.
