Figure 4-14. System Board Removal
To remove the system board, follow these steps:
1. Disconnect all cables from their connectors at the back of the
computer.
2. Remove the expansion-card cage.
3. Disconnect all cables from the system board.
4. Remove the screw that secures the system board to the bottom of the
chassis.
5. Slide the system board toward the front of the chassis until it stops.
6. Carefully lift the system board out of the chassis (be sure to lift evenly
and not twist the system board).
NOTE: If you are replacing the system board, remove all DIMMs, the video-
memory upgrade module (if present), the single-edge contact (SEC) cartridge/
heat sink assembly, and the guide bracket assembly from the old system board
and install them on the replacement board. Also, set the jumpers on the new sys-
tem board so they are identical to those on the old board unless a
microprocessor upgrade is being installed.
When you reinstall the system board (before you slide the system board back to
lock it in position), push down near each slot to engage the grounding clip onto
its corresponding tab. Push evenly on both sides of the system board as you
slide it into position (do not twist the system board).
