Remove the following ten screws securing the lower case to the upper case:

• Three 13.5 mm Phillips screws.
• Seven 3 mm Phillips screws.

Wedge your fingers between the lower case and the vent, and lift upward to release the clips holding the lower case to the upper case.

Remove the lower case.

Whenever working near the logic board, it is always wise to first disconnect the battery to avoid short circuits.

Grab the plastic tab attached to the battery connector and pull it toward the front edge of the device.

Pull the tab parallel to the face of the logic board.

Release the tabs on each side of the RAM chip by simultaneously pushing each tab away from the RAM.

These tabs lock the chip in place and releasing them will cause the chip to "pop" up.

After the RAM chip has popped up, pull it straight out of its socket.

Repeat this process if a second RAM chip is installed.
