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

• Three 13.5 mm (14.1 mm) Phillips screws.
• Seven 3 mm Phillips screws.

Using both hands, lift the lower case near the vent to pop it off two clips securing it to the upper case.

Remove the lower case and set it aside.

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.
