PowerBook G3 Wallstreet RAM Replacement

Remove both expansion bay modules using the levers on the front of the computer.

Insert your index fingers inside the expansion bays and search for the two ribbed tabs on the underside of the upper case. The tabs are located near the bottom corners of the keyboard.

Pull the tabs toward yourself and the keyboard will pop up.

Pull the keyboard forward to disengage the tabs holding it in back and rotate it toward you.

Rest the keyboard on the trackpad.

Disconnect the two keyboard connectors by disengaging the clamps and pulling the ribbons directly upward.

Slide a spudger downward between each plastic strain relief cable and the wall of the case in order to bow out the cable beyond the small tab holding it in place.

Once the strain relief cables are free, lift the keyboard off.

Your laptop should look approximately like this.

Remove the two Phillips screws from the heat shield.

Grasp the metal handle on the heat shield and pull up and toward yourself.

Unscrew, but do not remove, the single Phillips screw from the hard drive bracket.

Grasp the hard drive bracket on the left side and pull up and to the left.

Your laptop should look approximately like this.

Use a spudger, the tips of your fingers, or a flat non-metal tool to pry up the processor's right side.

Remove the processor by sliding it up and to the right.

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. There is a similar RAM slot located on the other side of the processor.
