NEWER flat screen iMac INSTRUCTIONS: Note: Disassembling the iMac probably voids the Apple warranty. (If something goes wrong or is damaged in the process, you're on your own.) Tools needed: Torx-10, Philips cross-head screwdriver. First of all you need to put the iMac on a soft surface - preferably cotton to avoid generation of static electricity. 1. You must remove the "User Access Plate", simply remove the 4 screws with the phillips driver. (Photo below is with User Access Plate removed.) 2. Remove the marked screws with a Torx-15. Then you can (carefully !!) take off bottom housing. It's a little bit tricky because there is a connector (see photo below - it's on the right side, when you look straight ahead onto your iMac) which fits pretty solid, but when you just pull strong enough on the bottom plate it loosens (but gently, please) OK, once you've got the iMac base open, you can see the battery (green and white cylinder on the right of the picture, below). Simply note which way round it goes, unclip it and clip in the replacement. Job done; now put it back together!
