Replacement Instructions

Follow the instructions in this sheet carefully. Failure to follow these instructions could damage your equipment and void its warranty.

Note:

Written and video instructions covering customer-installable parts are available at

http://www.info.apple.com/installparts/.

Warning: Sharp edges can exist inside your computer and on any parts being removed or installed. Use caution to avoid injury. Keep small parts away from children.

Tools Required

• Soft towel or cloth, larger than the PowerBook

• Torx T8 screwdriver (provided with hard drive)

Backing Up Your Data

Warning: Before replacing your hard drive, make sure you back up all data on the drive.

Opening the Computer

Warning: Always shut down your computer before opening it to avoid damaging its internal components or causing injury. After you shut down the computer, the internal components can be very hot. Let the computer cool down before continuing.

To access the hard drive, you must ﬁrst remove the battery and bottom case.

1. Place your computer on a clean, ﬂat surface.

2. Shut down your computer and wait thirty minutes before continuing.

3. Disconnect the power cord and any other cables connected to the computer.

073-0633 Rev. A

4. Place a towel or soft cloth on a table in front of you.

(Figure 1A)

The towel or cloth will protect the keyboard and display area of the PowerBook when you flip it over to remove the battery and bottom case. Make sure it covers an area large enough for your PowerBook and that it hangs over the edge of the table.

5. With the display open at an angle greater than 90 degrees, carefully ﬂip the Pow erBook o v er and la y it ﬂat, fully on the tab le . Make sure the display hangs over the edge of the table and rests lightly on your lap.

cable to the rib frame.

Note: For replacement, note that the flat side of the EMI clip holds the flex cable

secured to the rib frame. Slide off the EMI clip, and reserve it for reassembly. Then place the computer back in

position, so that the display rests lightly in your lap.

ports align completely with the openings in the back panel.

Note: When positioning the replacement logic board into the computer, check that

cables and connectors do not get caught under the board. Tilt the logic board toward the back panel, and place the following cables into the notches in the board:

• Power switch cable (reapply tape over the cable, if applicable)

• Backlight cable

• LVDS cable

Important:

be placing the original logic board back in the computer, use a razor blade to gently scrape away any residual thermal transfer material from the heat exchanger and the microprocessor chip.

Warning: When scraping away the thermal transfer material from the microprocessor chip, be careful not to nick the microprocessor chip.

Apply new thermal transfer material to the microprocessor chip as described in the next step.

Procedure

1. With the logic board removed from the computer, disconnect the fan connector from the logic board.

2. Turn over the logic board, and locate the cone-shaped pin at the right corner of the fan. Pull the rubber pin tight. Use a razor blade to cut through the rubber pin.

3. Turn over the logic board, and tilt up the fan to remove it completely from the logic board.

Note: The fan is secured to the logic board by a spongy, rubber adhesive lining on

three sides of the bottom of the fan. If there is any adhesive stuck to the surface of the logic board, remove it by rubbing it away. Do not use solvents.

4. When installing the replacement fan, first use a black stick to push the cone-shaped rubber pin into the hole on the logic board. (If necessary , use needlenose pliers to pull the rubber pin through to the other side of the logic board.) Then, peel away the protective cover from the adhesive that lines the three sides of the fan. Align the fan over the logic board opening and press the fan into place.

Note: If the cone-shaped rubber pin is too long, use a razor blade to cut the extra

length.

5. With the replacement fan installed securely and the fan connector connected to the logic board, reassemble and test the computer.

Procedure

1. With the computer on a soft cloth, remove the two identical screws from the top case.

2. Close the computer to an approximate 45-degree angle, and stand it on a soft cloth with the clutch covers facing up.

3. Remove the four identical Torx T8 screws from the clutch covers (two screws on each clutch cover).

4. Use a black stick to pry off the two clutch covers.

5. Open the computer so that the display rests in your lap and is protected by a soft cloth.

6.

Warning: Be especially careful when working near cables that attach to the display. If any of these cables are damaged, the entire display module must be replaced.

Warning: At the left clutch, the wrapped cable connected to the LVDS (low voltage data signal) connector is extremely delicate. Do not pull or pinch the LVDS cable. Do not allow the screwdriver to touch the LVDS cable.

Locate the two large silver-colored screws. Gently move aside the LVDS cable so you can access the screws.

Remove the two silver-colored Phillips screws from the left clutch. Notice that the screw closest to the LVDS cable has a sloped screw head.

Important: When installing the replacement display, make sure the screw closest to

the LVDS cable is the screw with the sloped head.
