Edit Step 19 Keyboard  ¶ 

  • Use a flat-edged tool to pop up both sides of the panel above the keyboard.

Edit Step 20  ¶ 

  • Unclip the top of the panel from the screen hinges and remove it. The screen must be rotated as far back as possible for this to work.

Edit Step 21  ¶ 

  • Remove the two screws from the top of the keyboard with a #1 size Phillips head screwdriver. It is recommended that you keep the screws in a small cup so that you don't lose them.

Edit Step 22  ¶ 

  • SLOWLY begin to lift the keyboard until you can see the ribbon cable attaching it to the computer. Disconnect this cable before completely removing the keyboard.

  • Before pulling out the ribbon, there is a tiny brown locking clip with two tangs you need to deal with. It is very hard to see. You will only see the two brown edge tabs. Slide both tabs a fraction of an inch towards the rear of the computer (the clip is not supposed to come loose), then the ribbon will slide free. When you put the ribbon back in place, make sure the clip is loose, then slide it back towards the front of the computer when you want to lock the ribbon into place.
