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). 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. 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 <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< Be sure that all power sources (including the battery pack, AC power cord, and Automobile Adapter) are removed from the computer before removing or replacing the internal AC power supply. Remove the two screws that attach the Automobile Adapter connector to the I/O bracket (Figure 4-44). NOTE: The screws for the Automobile Adapter connector are located under the Automobile Adapter door at the left rear of the computer (Figure 4-44). IMPORTANT: When replacing the Automobile Adapter connector (Figure 4-45), ensure that the long end of the connector [1] is next to the fan [2] and that the ferrite on the connector cable [3] is tucked between the short end of the connector and the right wall of the I/O bracket. If the connector is installed improperly, it interferes with the installation of the system board. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< To avoid a potential short to the computer, do not use a metal tool to remove the fan connector. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 14. Using a non-metallic tool such as the connector removal tool (Table 3-13), slightly press down against the top of the fan connector [1] to release the retentive force on the connector (Figure 4-46). Remove the fan connector [2] (Figure 4-46). 16. Remove the six screws that attach the system board to the computer base enclosure (Figure 4-47). IMPORTANT: To ensure proper alignment when replacing the system board, replace the screw noted as [1], then replace the screw noted as [2], then replace the other four screws (Figure 4-47). 17. Carefully tilt the system board up [1] and unplug the LED cable assembly from the connector on the bottom side of the system board [2] (Figure 4-48). IMPORTANT: When replacing the LED cable assembly into the connector, be sure that the soldered leads on the cable face away from the system board. With the system board still tilted up, slide the system board toward the front of the unit to release it from the I/O bracket, and remove the system board. Slightly flex the left side of the computer base enclosure toward the back of the unit [1] and remove the I/O bracket [2] (Figure 4-49). NOTE: The fan is integrated into the I/O bracket. [. . . ] If you installed a SCSI-2 hard drive, format and partition the drive. Refer to the Compaq EZ-SCSI Software Reference Guide for additional information. Reboot the computer by pressing the Ctrl+Alt+Delete keys to integrate the new information. If the computer does not automatically reconfigure the system when you turn it on, run Computer Setup ( Section 6. 7). [. . . ]
