G4 800 Dead except for power light

[Chris Fitzgerald]

I went to power up my G4 800 today only to discover that the only thing that happens when I press the "power on" button is that the power light comes on, but only for as long as I hold it. The machine will not boot, or even do anything other than light the light until I take my finger off. I think I heard about one of the G4's out at the studio doing this once, and it turned out it was something that apparently happens to a certain model of G4 towers when they are allowed to sleep for a long time (this one could be nicknamed "Rip Van Winkle" since I don't use it so often).

Any ideas about where to start? Life sure is exciting, isn't it?

Hi Chris, this happened to me once. You have to open your MAC and there is a little metalic button near the battery, just press it once to reset it.

Hope this helps.

Sorry for my English

Same exact thing happened to me...the button to press is the "PMU" button...just push it once, started right up for me after that.

Good luck!

Thanks, it fired right up after pressing the little button - you guys RULE! I love this board - I've gotten more good useful help here than almost anywhere else. I was so afraid that I was gonna have to replace the power supply or something.

While I'm pleased as punch to have the machine fixed so quickly and easily, it seems quite a strange little problem. Anybody know what causes it?

Peace,

Chris
