9.17 Cable Harnesses And PCMCIA Card Sensor This section covers removal and replacement procedures for the cable harnesses and the PCMCIA card sensor. Refer to Section 6.6 for more information about the cable harnesses and the PCMCIA card sensor.
1. Harness extension cable 2. Keylock switch 3. Eject switch cable harness 4. Eject switch 5. PCMCIA card sensor emitter 6. PCMCIA card sensor receiver 7. Power switch cable harness 8. Power switch NOTE: Refer to Section 9.18 for removal and replacement procedures for power switch and the eject switch components. Power Switch Cable Harness To remove the power switch cable harness, complete the following steps: 1. Remove the bottom cover (Section 9.6). 2. Remove the drive if one is installed in the drive cage above the power switch (Section 9.15). 3. Remove the drive cage above the power switch (Section 9.16).
4. Remove the power switch screw (Figure 9-38). IMPORTANT: The power switch screw is also used to attach one of the horizontal guides. When replacing the power switch, be sure the horizontal guide is still properly aligned (Section 9.19). 5. Remove the power switch from the top cover (Figure 9-38). IMPORTANT: If the power switch does not come out easily, the LED light pipes may be catching on the top cover. If this happens, press firmly on the light pipes while removing the switch to allow the light pipes to clear the top cover. 6. Disconnect the computer status sensor cables from the docking mechanism (Figure 9-39).
7. Remove the screws from the PCMCIA card sensor emitter and receiver frames (Figure 9-40). 8. Remove the receiver [1] and disconnect its cable [2] (Figure 9-40). 9. Remove the emitter [3] and disconnect its cable [4] (Figure 9-40).
IMPORTANT: When replacing the power switch cable harness, ensure that it is routed correctly. There are two types of cable harnesses: the type wrapped with tape and the type wrapped with tie wraps. The routing depends on which type of cable harness is being used. The type that is wrapped with tape should be routed underneath the drive cage, while the type wrapped with tie wraps should be routed behind the drive cage. (If the tie wrapped type is routed underneath the drive cage, it could interfere with installation of the drive.) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION >>>>>
IMPORTANT: When replacing the power switch cable harness, ensure that the cable harness is reconnected to the harness extension cable or the computer cannot dock properly. Ensure that the cable lock on the harness extension cable snaps back into place. 11. Remove the power switch cable harness (Figure 9-42).
PCMCIA Card Sensor (Emitter and Receiver) The PCMCIA card sensor is a light curtain type and is composed of emitter and receiver boards that are housed in individual frames. The receiver is located toward the front of the expansion base [1] while the emitter is located toward the rear [2] (Figure 9-43).
The emitter and receiver are similar in appearance. To tell them apart easily, note that the receiver frame has one small hole [1] and the emitter frame has two small holes [2] (Figure 9-44). The single hole in the receiver frame corresponds with a single infra-red component on the receiver board while the two holes in the emitter frame correspond with two LEDs on the emitter board.
NOTE: The small holes in the emitter and receiver frames may become blocked with debris that interferes with their operation. Before replacing the emitter and receiver, ensure that the holes are free of debris. To remove the PCMCIA card sensor emitter and receiver, complete the following steps: 1. Complete steps 1 through 9 as listed in Power Switch Cable Harness in this section to remove the emitter and receiver from the top cover. 2. To remove the emitter and receiver boards from their frames, gently pull back on the plastic snaps and lift the boards out (Figure 9-45).
IMPORTANT: When replacing the emitter board in its frame, it is possible to install it backwards. To connect the emitter board to the power switch cable harness, ensure that the connector on the board faces the outside of the expansion base. Eject Switch Cable Harness To remove the eject switch cable harness, complete the following steps: 1. Remove the bottom cover (Section 9.6). 2. Remove the drive if one is installed in the drive cage above the eject switch (Section 9.15). 3. Remove the drive cage above the eject switch (Section 9.16). 4. Remove the eject switch screw (Figure 9-46). IMPORTANT: The eject switch screw is also used to attach one of the horizontal guides. When replacing the eject switch, be sure the horizontal guide is still properly aligned (Section 9.19).
