Removal and Replacement Procedures - Desktop

5.19 System Board

To remove the system board, complete the following steps:

1. Remove the system unit cover (Section 5.6).

2. Remove the expansion boards (Section 5-8).

3. Remove the riser board (Section 5.10).

✎

It is not necessary to remove the riser brace in order to remove the system board.

If a replacement external battery is installed on the system board, do not unplug the battery
from the system board connector as that will erase the CMOS. Remove the external battery
from the hook-and-loop fastener on the chassis but leave it electrically connected to the
system board.

4. Disconnect any cables plugged into the system board.

5. Remove the front bezel (section 5.14.1).

6. Remove the drive cage (Section 5.17).

7. Remove the screws securing the system board to the chassis.

❏

Five screws secure Pentium system board.

❏

Seven screws secure Pentium II system board.
