[G4] G4 problems

[nagable at comcast.net]

Try removing the battery, pressing the PMU button and leaving the battery out for about 15 minutes.  Reinsert the battery, press the PMU button again and give it a try.  If this doesn't work, you will probably need a new logic board.  When you checked the battery, it MUST read at least 3.1v.  Good luck.
