Figure 4-22. 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).
If you are replacing a system board, remove the DIMMs and the microprocessor/
heat sink assembly from the old system board and install them on the replacement
board.
When you reinstall the system board, push down near each slot to engage the
grounding clip onto its corresponding tab, before you slide the system board
back to lock it in position. Push evenly on both sides of the system board as you
slide it into position (do not twist the system board).
