Schritt 1

Turn the computer so that the ports are facing you.
If the keyboard is locked, open the port cover and turn the keyboard locking screw until the keyboard is unlocked.

Schritt 2

Pull the keyboard release tabs toward you and lift up on the keyboard until it pops free.
Make sure you have removed the laptop battery and CD/DVD module from the expansion bays before proceeding.

Schritt 3

Lift the keyboard out by pulling it up and away from you. Rest the keyboard, face down, on top of the trackpad.
In order to replace the keyboard, you must first remove the modem.

Schritt 4

Remove the three silver Phillips screws that attach the heat shield to the internal metal framework.

Schritt 5

Lift the heat shield up and pull it toward you.

Schritt 6

Your laptop should look approximately like this.

Schritt 7

Pull the battery cable directly up from the logic board.

Schritt 8

Remove the battery from its holder by pulling up and to the left.

Schritt 9

Remove the two silver Phillips screws from the modem.

If the only task is removing/replacing the screen, the modem need not be removed.

Schritt 10

Use a spudger, the tips of your fingers, or a flat non-metal tool to get under the modem's edge and pry it up from its socket as shown in the picture.

Disconnect the cable from the right side of the modem.

Schritt 13

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

Schritt 14

Disconnect the keyboard cable from the logic board by pulling directly up on the clear plastic loop.
This step is out of sequence with the keyboard because in order to remove the keyboard you must first remove the modem.

Schritt 15

Your laptop should look approximately like this.

Schritt 16

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.

If the only task is removing/replacing the screen, the RAM need not be removed.

Grasp the orange cable at the left end of the hard drive and disconnect it from the logic board.
Try to grasp the cable on the plastic connector rather than on the flexible cable section.

Grasp the plastic tab and pull the hard drive up and to the left, making sure that the metal bracket doesn't catch on the black plastic casing.

Schritt 19

Push the display back so that it lies flat.

Schritt 20

Slip a spudger or your index finger under the clutch cover near the power button and pull gently upward until you feel it come free.
Repeat the previous step on the left side.

Schritt 21

Lift the clutch cover up and off, rotating it toward yourself.

Schritt 22

Grasp the orange display data cable and disconnect it from the logic board.
Pull the display cable straight up so that it is vertical.

Schritt 23

Grasp the thin display inverter board at its left end, push the left end forward to get the board beyond the tab, and then lift the entire board up.
There are two tabs that hold the display inverter in place that you need to get past in order to pull the board free.
