Thereare two on each side of the carrier. Two of the screws are shown in the photo insection 2.1 of the article on the left side of the drive carrier, andagain in the second photo in section 6, where they are highlighted. I found that if you remove the four screws that hold the DVD/CD drive tothe carrier you can slide the drive back away from the opening in thecase and easily lift out the carrier - without having to cut off theplastic bar mentioned above. ( Other iMac owner said removing the bar wasn't necessary)īefore you remove the "little black plastic bar": It's easy to remove with a sharp knife and easy to glue back on after you have installed the drive. I wasn't able to get the drives out until I removed the little black plastic bar that is glued onto the front of the CD-drive-tray. One note to the iMac-TFT-take-apart-article. Note/Update: I don't own an iMac G4 but a reader replied with a tip regarding this article, later contradicted by another iMac G4 owner.-Mike The iMac G4 1GHz-1.25GHz models use DDR333 RAM, up to 1GB dimms.) ( FYI - iMac G4/700-800MHz use PC133 ram (typically up to 512MB modules available). 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)Ģ.1 Now you can replace/upgrade the "factory" Internal (full-size dimm) Memory module, if thats all, go to step 6. Then you can (carefully !!) take off bottom housing. ( Apple's Customer Installable Parts (CIP) guides already cover installing the Airport card and RAM in the "User" slot there.)Ģ. Airport (802.11b) card and USER (sodimm) RAM slot shown. Photo below is with User Access Plate removed. First you must remove the "User Access Plate", simply remove the 4 screws with the phillips driver. I marked all important parts red (see pictures).įirst of all you need to put the iMac on a soft surface (I used a wool blanket, although this is not a good solution, as static electricity can damage electronic components.)ġ. Tools needed: Torx-10, Torx-15, Phillips-driver, thermal paste, spatula for paste
See the ESD warnings/procedures in Apple's iMac Flat Panel CIP page (Customer Installable Parts guides - covers ESD precautions, ("user slot") RAM and Airport card installs.)Īlso see below and bottom of page for other iMac G4 owner notes/tips/comments on this original article.
(If something goes wrong or is damaged in the process, you're on your own.) Any mods like this are done at your own risk. Note: Disassembling the iMac probably voids the Apple warranty.
