I have a Performa 476 that's rarely used, but today I tried to start it and it just sat there. The startup chime sounded normal, but the screen was black.

I tried to boot from a CD and from a floppy, but neither worked.

This Mac has been unplugged for several weeks at a time. I thought that a dead battery might be the problem, but that seems pretty unlikely.

Any ideas that might help are certainly welcome.

Thanks.

does the light come on the monitor? does it stay a specific color (green/amber?) you might want to try another monitor, it could be the monitor or the video card even. I'd try that out next, the proceed from there.

Your battery is dead, that's all. You could force it to boot up but there isn't any point; it's just a hit and miss process.

Replace the battery and you'll be right

I'm not sure if this is correct, but you could try pressing a reset button found on your motherboard (as previously discussed in MacAddict). This is the best way of cleansing your system, as it even helps "revive" dead Macs.

Thanks for the replies, guys.

Yes, all the lights on the monitor, CD, modem, and printer light up. The monitor light is a steady green. The fan hums, too.

I'll replace the battery ASAP. I thought a dead battery would only foul up the PRAM settings, but maybe it also fouls up other stuff, too.

I searched for the MacAddict thread, but found only a reference to the rest button on the CUDA board. I have no idea what that might look like on a 476, but I'll look for it. If you don't hear back from me in a few days, I got zapped.

It's odd, to me anyway, that it won't boot even from a CD. That's what really scares me about this.

Thanks again.

Trust me, your machine is absolutely fine. Just replace the battery and it'll be in working order

Not to pipe in when a topic is solved...

But once again, wierd acting Macs are often, not always, but often acting that way because of a dead PRAM battery. There is no recipe or consistant way that they act wierd, but they act wierd and replacing a battery is relatively inexpensive in the long run.

I replaced the battery ($11 at RS) and rebooted. All is well.

Mac slowly booted to a Happy Mac, then automatically rebooted to another before displaying the desktop.

The only time I've had a battery problem was years ago. The Mac booted, but the time and date were wrong. I guess that battery was just weak, whereas this one was flat out dead.

Thanks for the help, guys.
