IMac Won't Boot

[PDG]

I just noticed this cute orange iMac from 1999 sitting out in our storage area all by itself. I brought it in, hooked up a keyboard and plugged it into the wall. When I press the power button on the keyboard or case it won't power at all. No colors, lights, noises or activity of any sort. Total death.

With a PC, this normally means a dead Power Supply. Does it make much difference on a Mac? Could it be something else like a battery, etc? Just curious. It'd be nice to get it working.

Flat battery just means all the system settings (clock etc) would be gone. First up (you'd be surprised) Check the fuse in the plug. Then it's the power supply.

With the original iMac that's a nightmare to get at but is possible just involves taking the whole thing apart. You can find PDF's about the www that tell you how. I severely doubt if it's worth it though. (64Mb RAM)

Thanks for the advice. I checked out the fuse and plug & both are fine. I'm thinking it's the PS and I'm not ready to rip that puppy open. Ah well...

What Dave said - 3000 volts from the HT cap is not the best way to start your day. Actually, unplugging it, then turning it on should do the trick, it depletes the capacitors.

But then, as it's not working at all, that may be academic.

Actually.... dead battery will prevent a power up in my experience. So.... Power supply or battery if there's no lights.. clicking.. flicker or anything.

[Dave]

Boot up memory would have gone too.

Still I'd love to plug in that old Commodore 64 and play some of those wonderful games .... SIGH :)

Well, I've removed the battery in the past and all it's done is lost the settings but there you go.

Dave two words mate:

emu

later

;)

[Scott]

yeah... it will lose the settings but if the battery is completely dead the Mac may not boot. it's a long shot... but we.... power supply would be my first guess. But I have, in a couple cases seen someone replace the battery in a non-booting Mac and BAM it boots. Hasn't happened to me, but I've seen it with others a couple times.
