How hard is it to replace the back up battery on an Rev B iMac? Where could I find instructions or a guide? I've added RAM to my iMac, but now that it's two years old, I wonder when the battery will go?
It's not getting what you want, it's wanting what you've got.
Actually Ruddiger doing one of the updates from Apple itself can kill your battery. It did it to mine and *alot* of people's computers. I don't remember excactly what it was though. I'm thinking the ROM update or firmware update. Mine has been dead ever since I've done it.
joeswell you can find just about anything if you are willing to look. I believe though you have to get down inside your iMac to get to it. It is no where near as easy as adding RAM or an Airport Card. I'm not sure but it could void the warrenty. (Just had to say that) if you have any idea how to use a screw driver and know to touch something metal before reaching into your comp (to ge rid of any static electricity you may have) you shouldn't have a problem.
