G3 iMac and Battery

Message #1 - Posted 2007/09/03 - Sleepmac

500 mhz G3 iMac. OSX 103.9. The date and time were not holding. I checked the battery, although installed correctly, it was dead. I replaced the battery with a new one that checked out at 3.6 volts. The iMac refused to bootup! I scratched my head, and on a whim, I installed the new battery opposite from the correct position. The computer now starts and runs fine, but it doesn't hold the date and time again. The + and - battery terminal positions are displayed prominently on the board holder. And as I said above, I know the old battery was installed correctly.

Any ideas?

Try to clean the bettery holder terminals with some isopropyl. The poles =

might have been moistered with some verdigris.

Then press the small PRAM button/CUDA button and hold it down for 4-5 sec= s.

In connection with the battery holder there is a small print containing=20 a condensor. If this condensor has been drained for the voltage, it has=20 to be 'recharged' before the battery will be able to work again.

Thanx, I'll see what I can do with it in a few days. :-)
