Step 1 — Battery

Use a coin to turn the battery lockingscrew 90 degrees clockwise.

Lift the battery out of the computer.

Step 2 — Upper Case

Remove the four Phillips screwsfrom the memory door.

Slide the memory door away fromthe memory compartment.




Step 3

Remove the following 8 screws:

Two 3 mm Phillips in the batterycompartment, on either side ofthe battery contacts.

Two 9 mm Phillips on either sideof the memory compartment.

Four 16 mm Phillips along thehinge.

Step 4

Rotate the computer 90 degreesclockwise, so that the powerreceptacle faces you.

Remove the three 3 mm Phillipsscrews.

When replacing these screws, youmust place each screw in the correctorder. Begin by installing the screwclosest to the display hinge, and goout from there.




Step 5

Turn the computer 90 degreesclockwise so that the hinge facesyou.

Remove the bottom 5 mm Phillipsscrew on either side of the hinge(two total).

Step 6

Rotate the computer 90 degreesclockwise, so that the ports faceyou.

Remove the three 3 mm Phillipsscrews.

When replacing these screws, youmust place each screw in the correctorder. Begin by installing the screwclosest to the display hinge, and goout from there.




Step 7

Turn the computer over and openthe display.

Remove the 4.2 mm 1/16" H 1.5 hexscrews in either corner, next to thedisplay (a T6 Torx driver will also dothe job nicely).

Step 8

This step covers the hardest part toget inside this computer. Take adeep breath and think happythoughts.

Grasp the back corners of the uppercase and pull up, disengaginghidden tabs on the sides. Do not pullthe upper case off yet; you still needto free tabs in the front of the case.

The seam is beneath the plasticmolding on the upper case.




Step 9

There is one latch that stops youfrom pulling the upper case right off,located on the left side of the opticaldrive slit. To free the upper case,you will be pulling a thin metal latchtoward you, freeing it from the claspholding it in place.

Pry up the left side of the upper caseslightly with your hand and wedge aspudger into the seam between theupper case and lower case.

Leave the tool in place applyingpressure to the upper case for thenext step.




Step 10

Place enough pressure on the uppercase to allow you to slide a tool justwithin the seam between upper caseand lower case as shown in thepicture. A dentist's hook, push pin,or similar tool will work.

Do not yank the upper case off assoon as you free the clasp. Thecase is attached to the logic boardvia two ribbon cables.

Delicately slip the tip of your toolbehind the silver metal latch and pullit forward while pulling up on thecase. This may take some effort.

Alternatively, you can free the claspwith a small flathead screwdriverthrough the CD slot. The clasp is 1-3/16 in (3cm) from the left side of theslot. Use the screwdriver to lift out(or press back) the felt lining; thenuse the screwdriver to pull the clasp(shiny metal) forward to free it fromthe catch behind it (dull metal).




Step 11

Lift the back of the case up andwork your fingers along the sides,freeing the case as you go. Onceyou have freed the sides, you mayneed to rock the case up and downto free the front of the upper case.

Rotate the upper case up andtoward the screen, so that the uppercase rests against it.

Step 12

Remove the orange tape securingthe trackpad ribbon to the logicboard.

Disconnect the trackpad ribbon fromthe logic board.




Step 13

This is a diagram of the keyboardribbon clamp connector you willdisconnect in the next step.

1) With your fingernails, grasp thelocking bar on either side and pullup a small amount (about 1/16" or 2mm).

2) After disengaging the locking bar,slide the cable out of the connector.

Step 14

Loosen the keyboard ribbon clampby pushing the thin black piecetoward the screen, using the tips ofyour fingers.

The black piece is very fragile andeasily broken. Use care whenseparating it from the main socket.

Slide the grey keyboard ribbon outof the loosened connector.

Remove the upper case from thecomputer.

Your laptop should lookapproximately like this.
