Step 1 — Battery

Use your fingers to push both battery release tabs away from the battery, and lift the

battery out of the computer.



Step 2 — RAM Shield

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.

Remove the two 2.8 mm Phillips

screws in the battery compartment

near the latch.



Remove the following 6 screws:

Two 10 mm T6 Torx screws on

either side of the RAM slot.



Four 14.5 mm Phillips screws

along the hinge.

Step 8

Do not yank the upper case off quickly. The case is attached to the logic board via a

ribbon cable.



Lift up at the rear of the case and work your fingers along the sides, freeing the case as

you go. Once you have freed the sides, you may need to rock the case up and down to

free the front of the upper case.



There are four plastic clips above the DVD slot, and another above and to the left of the IR

sensor. These clips can be very difficult to disengage without prying. They can also be

difficult to re-engage during reassembly.



Reassembly Tip: Press down firmly on the tip of the top case above the location of each

clip until you hear a snap to reseat them in their slots.



Reassembly Tip: The two center DVD clips will rarely snap back into place properly

without help, and downward pressure will instead simply deform the frame around the DVD

slot. Support the frame by inserting a plastic spudger into the DVD slot directly under the

clip location until it is snug, then press down until you hear the snap.

Step 9

Disconnect the trackpad and keyboard ribbon cable from the logic board, removing tape as

necessary.



Note: It is possible to replace the hard drive without disconnecting the keyboard from the

chassis, but it will need to be held upright to keep it out of the way, while still allowing you

both hands to work on the drive removal. Be careful when removing the keyboard-trackpad

ribbon cable to ensure that the rear of the upper case is disengaged from the area near the

hinge. It is easy to accidentally bend the screw receivers on either side of the keyboard.



Remove the upper case.

Use the flat end of a spudger to

disconnect the orange SuperDrive

ribbon cable from the logic board,

removing tape as necessary.



Step 11

Remove the following 4 screws:

Two 3.3 mm silver Phillips screws on either side of the SuperDrive.

One 4.7 mm silver T6 Torx screw from the top left corner of the drive.
