Power Mac G4 Tower Shut Itself Down, Won't Start Now
Power Macintosh G4 500 DP (Gigabit) M7893LL/A*
Wouldn't power up a couple of months ago. Randomly one day after several weeks I hit the power button and it was fine. Have used it 4-5 times over a couple of weeks since then. Tonight after about 3-4 minutes it shut down as if the power cord had been pulled. It will not power up. I was using a browser when it happened. I know the AC cord is live, I can hear the small electrical click when the contacts make a connection with the machine. The PRAM(?) battery reads 3.7v with a meter. I removed it for 10 minutes once and then an hour once, following reset procedure to no avail. All peripherals were disconnected during attempted reset. I do not see any lit LEDs on the motherboard although I don't recall ever seeing one but I have read that maybe there is one. (A few years ago I replaced the power supply after the tower would not power up following a neighborhood power outage due to lightning. We seem to have several outages each year in this area. Just background info, don't know if there's any relation to current problem.)
Is this a good question?
