[. . . ] Remove the keyboard cover (Section 4. 7). Remove the hinge cover from the top of the internal AC power supply by sliding it toward the front of the unit (Figure 4-40). 3. Remove the two screws that attach the power supply to the top of the system unit (Figure 4-41). 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. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> CAUTION <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< To avoid damage to the internal AC power supply, be careful when lifting up on it, since the cable is still attached. Do not attempt to fully remove the internal AC power supply until the cable is disconnected. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>><<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< 5. Lift up the power supply to allow access to the power supply cable (Figure 4-43). Disconnect the internal AC power supply cable (Figure 4-43). Remove the internal AC power supply (Figure 4-43). 4. 17 System Board And Input/Output (I/O) Bracket To remove the system board and input/output bracket, complete the following steps: 1. If a new system board is to be installed, remove the memory expansion board (Section 4. 6). 2. Remove the keyboard cover (Section 4. 7). 4. If a new system board is to be installed, remove the processor board (Section 4. 13). 5. Disconnect the auxiliary battery (Section 4. 8). Remove the display assembly (Section 4. 9). Remove the keyboard (Section 4. 10). 8. Remove the diskette drive and cable (Section 4. 11). Remove the internal AC power supply (Section 4. 16). Remove the eight screwlocks that attach the rear I/O connectors to the I/O bracket (Figure 4-44). Remove the screw that attaches the keyboard/mouse connector to the I/O bracket (Figure 4-44). 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. [. . . ] Run Computer Checkup to ensure that the drive is working properly (Section 2. 3) NOTE: Refer to the Compaq EZ-SCSI Software Reference Guide for additional information on SCSI drivers and on formatting and partitioning a SCSI-2 hard drive. F. 5 Connecting An External SCSI-2 Device This section covers procedures for connecting an external SCSI-2 device to the expansion base. NOTE: Prior to connecting a SCSI-2 device, refer to the SCSI-2 drive manufacturer's instructions to verify the parity, termination, and SCSI ID of the drive and to obtain additional installation information. To connect a SCSI-2 device to the expansion base, complete the following steps: 1. Connect the Compaq external SCSI-2 cable (included with the Compaq SCSI-2 device) to the expansion base and the device. Turn on the expansion base (computer must be docked first). Install the SCSI-2 drivers to allow the computer to recognize the SCSI-2 device(s) connected to the expansion base (Section F. 6). [. . . ]
