Step 14
Loosen the keyboard ribbon clamp by pushing the thin black piece toward the screen, using the tips of your fingers.
The black piece is very fragile and easily broken. Use care when separating it from the main socket.
Slide the grey keyboard ribbon out of the loosened connector.
Remove the upper case from the computer.

Display
If you have already removed the hard drive or optical drive, your computer may differ slightly from the images in this section. These parts do not affect this procedure.
Close the display and turn the hinge side of the computer to face you.
Remove the remaining Phillips screw on either side of the hinge (two screws total).





Be very careful! The clasps holding the black strip are extremely fragile and can snap very easily.
In fact it is possible to get to your hard drive and replace it without having to detach this ribbon at all and I would advise that if all you are doing is replacing your hard drive then skip this step.
My laptop did not have the big gray keyboard ribbon but a short white one with a blue stripe at the end. Anyone knows if this is just a different setup?
my g, 15", 1.5Ghz pbk didn't have this cable at all. It's short white kbd cable attached to the trackpad, and it's orange ribbon cable (only) attached to the logic board as in step 12. lucky me.
