IMPORTANT: When replacing the hard drive security clips, position each clip over the notches in the plastic rib near the front of the hard drive enclosure. Insert each clip until the top surface of the clip is flush with the top surface of the plastic rib. If the clips are not flush, the keyboard will not fit properly. Note the orientation of the clips in Figure 4-32. 8. If a hard drive lock label is attached to the front of the hard drive, remove it. NOTE: If you wish to install the hard drive security clips and lock label on the replacement hard drive, do so before completing steps 9 and 10, while the computer is still disassembled. 9. Replace the keyboard (Section 4.10). 10. Replace the keyboard cover (Section 4.7). 4.13 Processor Board

removing or replacing the ejector rails. Removing the PCMCIA Ejector Rails To remove the PCMCIA ejector rails, complete the following steps: 1. Remove the keyboard cover (Section 4.7). 2. Remove the PIB, PIB insulator, and PIB shield (Section 4.14). 3. Remove the top ejector rail by sliding it gently but firmly out of the system unit (Figure 4-37). 4. Repeat step 3 for the bottom ejector rail. Replacing the PCMCIA Ejector Rails IMPORTANT: When replacing the ejector rails, be sure that the metal eject lever on the rails seats fully into the narrow slot in the PCMCIA connector. If the rails are not fully seated in the slot in the connector, they will not line up with the holes for the
mounting screws. To replace the PCMCIA ejector rails, complete the following steps: 1. Slide the bottom ejector rail into position until it locks into place (Figure 4-38). 2. Slide the top ejector rail into position until it locks into place (Figure 4-38). 3. Insert the PCMCIA spacer into the rails to assist with rail alignment (Figure 4-39).
4. Replace the PIB, PIB insulator, and PIB shield (Section 4.14). NOTE: After installing the screws for the PIB, the PCMCIA spacer can be removed or left in the PCMCIA slot for storage. 5. Replace the keyboard cover (Section 4.7). 4.16 Internal AC Power Supply NOTE:The DC-to-DC power supply is integrated into the system board. To replace the DC-to-DC power supply, the system board must be replaced. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> WARNING
Do not disassemble the internal power supply, as there are no field serviceable parts inside. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
4. Remove the two screws that attach the power supply to the rear of the system unit (Figure 4-42). NOTE: To allow the screws to align easier when replacing the power supply, replace the two rear screws before replacing the two top screws.
