  • To lift the front bezel off the iMac, simultaneously:

    • Use your thumbs to press in the RAM arms and hold the iMac down.

    • Use your index fingers to pull the small bridge of material on the front bezel toward yourself.

    • Pull the front bezel up with your index fingers.

  • Once the small bridge of material has cleared the RAM arms, lift the front bezel by its lower edge just enough to clear the bottom edge of the rear case.

My iMac did not have the "small bridge of material" mentioned, however the bezel just lifted off easily.

I found it easier not to remove the cables connecting camera and microphone, but rather to lean the plastic frame agains a pile of books so that it could rest almost vertical avoiding the need to disconnect those two sensitive cables.

I agree that for a simple, quick battery change, don't risk damaging those delicate wires. Ignore Step 6 and instead of disconnecting the mic and camera wires, keep them in place and just have a friend hold the plastic frame up while you change the battery, or prop it up as mentioned by Stefano C above.

Make sure you double check the new logic board for the presence of the GPU assembly before installing. I stupidly installed a new board without moving the GPU from the old one first. So i guess you can say this guide worked for me twice. :)

  • Push down on the optical drive bracket retaining clip while pulling the top edge of the optical drive away from the rear case.

Looking at pic on step 18, if you follow the black plastic release clip downwards there is another clip (just below the drive) so you need to pinch them together (with the optical drive in the middle), rather than just press down on the top clip.

If you look at the picture on step 19, you will see the corresponding release clip (just behind the middle of the orange ribbon cable) but it's not immediately obvious to see unless your looking for it.
