Turn the keyboard locking screw so that it is parallel to the space bar.
Pull the keyboard release tabs toward you and lift up on the keyboard until it pops free.
Lift the keyboard out by pulling it up and away from you. Rest the keyboard, face down, on top of the track pad.
Pull the keyboard ribbon straight up from the logic board. Place the keyboard aside.
The connector may be tight. Gently rock the connector from side to side while pulling directly upward to free it. You can use this technique on many of the cards and cables you'll be disconnecting.
Make sure you have removed the laptop battery and CD/DVD modules from the expansion bays before proceeding.
Grasp the plastic tab on the processor's right side and pull it directly up.
Some processors may be missing the plastic pull tab. In this case, we suggest using a non-metal tool to gently pry up the processor. Slip the tool's thin edge under the front right corner of the processor and carefully pry it up.
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 RAM chip out.
There are RAM slots on both sides of the processor. We recommend installing higher capacity chips on the bottom so that if you want to upgrade later, you won't have to remove the processor.
