Accessing the RAM is easy.
Use your fingers to push both battery release tabs away from the battery, and lift the battery out of the computer.
Remove the three identical 2mm PH000 Phillips screws from the memory door.
Lift the memory door up enough to grip it and slide it toward you, pulling it away from the casing.
Release the tabs on each side of the RAM chip at the same time. These tabs lock the chip in place and releasing them will cause the chip to "pop" up.
Pull the chip directly out from its connector.
