HOLD UP!

Make sure that you have the instructions for the specific iMac you  
have!!! Apple made many changes as the iMac evolved.

To make this point clear, the instructions for removing the back cover  
on an iMac G5 (Ambient Light Sensor, no isight) does NOT say to remove  
the screws. The screws get turned counter clockwise until light  
resistance is is encountered. The screws are captive and operate  
internal clamping mechanisms.

The iMac G5 (with isight) requires that the FRONT panel is removed.  
The 3 screws at the bottom are removed AND the 2 latches at the top  
corners of the machine are released. This is done by inserting a tool  
up through the cooling vent on the rear and engaging the release  
mechanisms.

I should also point out that there is no mention of an internal  
battery for the iMac G5 (with isight) in the service manual I have.

If you'd explain why you think you need to replace this battery, maybe  
we could help...
