A possible fix for a Mac that won't power up
Authored by: Riker29 on Apr 12, '05 10:53:08AM

PMU reset and/or battery removal can fix many problems.

Here is another hint:

On some Macs (like the G5 iMacs) actual REMOVAL of the battery can be difficult. A workaround is to get a small piece of paper (something which is a bit stiffer than normal paper works best like a matchbook, index card, etc.) and just slip this under the top battery contact. This effectively disconnects the battery.

Wait a good 10-15 minutes, then remove the paper, and start up.
