SOS style beeps on P.O.S.T.

What do 3 short, 3 long, 3 short beeps, mean at POST, on a MA876LL, iMac7,1?

It does nothing else! No light on display.

I looked in the answers for decoding beeps, but the listseems to show only one beep to five beeps, not a series as this.

Could be major failure indication??

iMac, Mac OS X (10.6.8), 20" iMac 9.1, A1224

Several years ago I had one of my 24-inch iMac's exhibit a very similar issue. My service tech was able to resolve the issue by removing the small coin battery from the logic board for a couple of minutes and then installed a new one after checking the battery voltage. He didn't have to replace any parts other than the battery. Hopefully that's all your system needs.


This link shows what the battery looks like:

Thanks for this suggestion. I'll try that fix.

Unfortunately the apple support threads on 'POST beeps' only list a single sequence, 1 to 5 beeps in both

Since posting this thread, the 'More Like This' helpful suggestions, on the right side, has turned up two similar beep sequence experiences. http://support.apple.com/kb/HT2538?viewlocale=en_US

and http://support.apple.com/kb/HT2213

So I have a couple of others to check too.

Thank you again for your help. It's most encouraging.

Clive.
