2. Remove the computer cover.
   
   
3. Remove the drive shelf assembly.
   
   
4. Remove the expansion-card cage.
   
   
5. Remove the hard-disk drive/bracket assembly.
   
   
6. Disconnect all cables from the system board.
   
   
7. Remove the screw that secures the existing system board to the bottom of the chassis
   
   Before you remove the existing system board, visually compare the replacement system board to the existing system board to make sure that you have the correct part.
   
   
8. Slide the system board toward the front of the chassis until it stops.
   
   
9. Carefully lift the system board out of the chassis (lift evenly and do not twist the system board). Place the system board that you just removed next to the replacement system board.
