Here's the problem. Have an iMac that will not power on if the bios/firmware battery is in. It will however run perfectly well without the battery ie powers up, reboots. I would like to be able to fix this problem and I beleive I could do this by updating the firmware (although might be well off the mark :whistle:

I tried to see if there was a jumper like that on a pc motherboardto jump the bios but couldnt see one that i recognised.
Tried removing hard drive, power battery and powering down but no difference.

Cant update the firmware from OS as you need to power off and without the battery obviously loses the data.

Has anyone got any clever ideas other than give up and just use it without the battery lol.

You need to get a new battery if it is dead I believe that it will not run.
If I have replied to a topic and you reply and I haven't gotten back to you within 48 hours (2 days) then send me a P.M.
