R
ecommended Tools
Most of the procedures in this appendix require the use of one or more of the following tools:
• Small flat-blade screwdriver
• Jeweler’s screwdriver set
• Number 1 magnetized Phillips-head screwdriver
• Number 2 magnetized Phillips-head screwdriver
• Chip-removal tool
• Wrist grounding strap
• Small plastic scribe
• Nut drivers
P
recautionary Measures
Before you begin working on the computer, read about the precautionary measures, screw identification, and computer orientation outlined at the beginning of Chapter 4, “Removing and Replacing Parts.”

ard-Disk Drive
The hard-disk drive resides in a carrier that mounts inside the computer’s hard-disk drive bay. Four screws secure the drive inside the carrier. A mylar insulator provides electrical insulation between the hard-disk drive and the bottom of its carrier. To remove the hard-disk drive and hard-disk drive insulator, follow these steps:
1. Remove the hard-disk drive assembly.
See “Hard-Disk Drive Assembly” in Chapter 4.
2. Place the hard-disk drive assembly right side up on the work surface, and remove the four screws that secure the drive in its carrier.
CAUTION: Rotating the hard-disk drive too far can damage the short flex cable that connects the hard-disk drive to the system board’s hard-disk drive interface connector. Do not rotate the drive farther than necessary to disconnect the cable from the back of the drive.
3. Rotate the front of the drive toward the back of the carrier far enough to expose the connector on the back of the drive.
4. Carefully pry the flex cable connector away from the hard-disk drive interface connector on the back of the drive.
5. Lift the hard-disk drive out of its carrier.
6. Remove the hard-disk drive insulator, if necessary.
With the hard-disk drive removed, lift the insulator straight up out of the carrier. The 17-mm hard-disk drives also have a foam spacer on top of the insulator (not shown).
To avoid possible damage to components on the hard-disk drive’s integrated controller board, hold the drive at approximately a 45-degree angle while reattaching the interface cable. Then rotate the drive toward the front of its carrier until it is seated in its original position.

D-ROM Drive
The CD-ROM drive is attached to the CD-ROM/diskette drive bracket. See
“Diskette/CD-ROM Drive Assembly” in Chapter 4 for instructions about removing the diskette/CD-ROM assembly from the bottom case assembly. The
CD-ROM flex cable is threaded through a slot in the drive bracket. Remove the four screws that hold the CD-ROM to the drive bracket. Slide the CD-ROM flex cable out of the slot in the bracket holding the CD-ROM. The CD-ROM is replaced as a unit and is not disassembled.

The diskette drive is attached to the CD-ROM/diskette drive bracket. See
“Diskette/CD-ROM Drive Assembly” in Chapter 4 for instructions about removing the diskette/CD-ROM assembly from the bottom case assembly.
Remove three screws to separate the diskette drive from the drive bracket. The diskette drive is replaced as a unit and is not disassembled.

almrest Assembly Components
To remove and replace a component of the palmrest assembly, you must first remove the assembly as described in “Palmrest Assembly” in Chapter 4. The subsections that follow provide removal procedures for the components of the trackball assembly. See Figure A-2.
Trackball
Turn the trackball board over. Rotate the retaining ring counter-clockwise. Lift the trackball out of the recess in the trackball holder.
Trackball Interface Cable
Gently disconnect the end of the cable from connector J1 on the trackball button board.
Trackball Button Board
Remove retaining screw A6 (see Figure A-2), and lift the board out of the palmrest assembly. When replacing the board, fit the two small switches on the underside of the board into the recesses in the palmrest.
Palmrest Brace
Remove screws A-7 through A-9 (see Figure A-2). Gently pull the brace toward the front, and lift the brace away from the palmrest.

isplay Assembly Components
The display assembly consists of the LCD assembly and its related components.
It also contains the LED board, which provides visual indications of many of the computer’s basic functions. The microphone assembly is mounted inside the right hinge cover of the display.
Some parts of the display assembly can be removed and replaced without removing the assembly from the computer. Others require that the display assembly be removed. The following subsections describe the removal of display assembly parts.
Display-Assembly EMI Shield

6. Remove the display assembly base.
See “Display Assembly Base” later in this chapter.
7. Remove the display-assembly EMI shield.
The EMI shield is held in place by tabs along the upper and lower edges. Pulling the center of the shield slightly away from the display assembly will release the tabs.
To replace an EMI shield, carefully orient the replacement EMI shield in the same position as the original shield. Make sure that all screw holes in the shield are aligned with their corresponding screw holes in the display assembly case.
Display Assembly Base
To remove the display assembly base (see Figure 4-14), follow these steps:
1. Remove the display assembly from the computer.
See “Display Assembly” in Chapter 4.
2. Remove both hinge covers.
See “Hinge Covers” in Chapter 4.
3. Rotate the display assembly hinges so that they point away from the display assembly at approximately 180 degrees.
4. Remove the display assembly bezel.
See “Display Assembly Bezel” in Chapter 4.
5. Remove the left hinge.
See the next subsection, “Display Assembly Hinges.”
6. Rotate the right end of the display assembly base away from the display assembly until the base clears the right hinge.
7. Lift the display assembly base away from the left hinge.
8. Disengage the display-assembly interface cable from the slot in the base.
