View Full Version : Replacing PRAM battery in 20" iMac G5 w/ iSight.

A couple months ago I opened up my 20" iMac G5 iSight and replaced the "Superdrive" and the hard disk. While I was in there I completely forgot to change the PRAM battery.

It really wasn't too bad digging around inside but I was wondering if anyone has a photo or remembers where the PRAM battery is located in this model? I don't remember seeing it when I was changing the other components. :confused:

Thanks in advance! :)

assuming there's only one battery then think it's about half way up closer to the lhs than the rhs.

iirc it's a button battery about 1-1.5cm across.
