i have an old mdd running tiger, and every once in a while if i put it to 
sleep overnight, then come back, it has actually powered itself back on, 
and sometimes i find that it has shut itself off when i come back in the 
morning.

when it does this i have a hard time getting it to power back on again and 
i usually have to disconnect the ac power, then press and hold the power on 
button for a second, then plug the ac cord back in and it would power on 
again when i pressed the button.

yesterday i couldn't get it to power back on and i unplugged the ac and hit 
the pmu button for a few seconds then plugged everything back in
and it came on again.

last night i actually powered it down, and today it will no power back on 
no matter what i try.

when i push the power button on it briefly lights up then goes out. if i do 
it a few times in a row the light will stop coming on, unless i leave it 
alone for several seconds.


is my power supply dead or is there some other problem?


thanks

rb
