The inside of my iMac G5 17" does not look like the one you have. What I assume is the PRAM batter is completely exposed. Can this be anything but the PRAM battery?

First look on the bottom of your stand to get the exact model of your iMac. Your PRAM battery is probably covered by the airport card. You may need to remove the card to gain access to it. Here’s the guide on the battery replacement. iMac G5 17" Model A1058 PRAM Battery Replacement

I have changed the battery. It was not under the airport card. I have one other question. The information on the bottom of my stand doesn’t seem to indicate a model number. Is it part of the serial number?

I’m not sure what this is a picture of but it does not look like my machine (1058). I don’t see any way to send you a photo of the inside of my machine but there is nothing in the way or on top of or covering the PRAM battery. The Airport card / module is somewhere else. I need some clarification as to the amount of bending and pulling I can get away with when I start fiddling with the retaining clip on mine, which BTW, appears to be much more substantial than the one in this picture / procedure. Can you please verify that this is the procedure for a 1058? Also BTW I see I am ten years late for this but I still need some expert help here. Fifteen minutes later - boy, I am stupid (or not, see below). Now I see that while I have model A1058 it is in fact EMC 2055. So maybe never mind while I search your website or maybe I’ll be back if I don’t find what I want. Too many numbers for this guy, above my pay grade as we say. Ok, now about five minutes since the previous and no luck finding a picture of my PRAM battery on the site. Still not sure how stupid I am but certainly will admit to confusion.
