Pull the keyboard release tabs toward you and lift up on the keyboard until it pops free.
If the keyboard does not come free, use a small flathead screwdriver to turn the keyboard locking screw 180 degrees in either direction and try again.
Flip the keyboard over, away from the screen, and rest it face-down on the trackpad area.
Before you can yank the upper case off with joy, you must disconnect both the blue and white power cable and red and black speaker cable as described in the next steps.
Lift the upper case from the left side and use your other hand to pull out the right side in order to clear the power receptacle.
There may be a thin metal bar fastened to the upper case by the two screws on either side of the optical drive. This bar provides rigidity around the optical drive; don't forget it when reassembling.
The connectors at the ends of the cables are attached very firmly to the sockets on the logic board. Pulling directly on the cable will either separate the cable from its connector or the socket from the logic board.
Lift the upper case enough to disconnect the blue and white power cable from the logic board. Using your fingernails or a dental pick, carefully pry the connector from its socket. Make sure you're pulling only on the connector and not on the socket.
