I successfully replaced the hard drive in my g4, though when I got to the step to remove the keyboard ribbon cable, I skipped it after snapping off the outside of the white connector while trying to execute step #13. Everything is still snug and the keyboard works fine. My problem is that I also have to replace the keyboard in the near future. I'm concerned about steps #13 and 14 since I've already broken off a tiny piece of the clamp mechanism.
What does this instruction mean in step #13: 1) With your fingernails, grasp the locking bar on either side and pull up a small amount (about 1/16" or 2 mm)? This is where I broke off a tiny tab on the right side. It isn't clear how the cable is removed in step #14. Any advice on this step is much appreciated.
