Main Board
Figure 4-34. Main Board Removal
To remove the main board, follow these steps:
1. Remove the processor board.
2. If one is installed, remove the LVDS board. Otherwise, go to step 3.
3. Remove the USB board.
4. Remove main board screws M1, M2, and M3.
5. Remove standoff nuts ST1, ST2, and ST3.
6. Remove the main board from the base assembly.
Lift the end of the board nearest the front of the computer, and pull the
board up and out of the computer.
Remove the I/O panel bracket only if you have to replace it. The I/O panel
bracket can be removed from the main board by removing standoff nuts ST4
through ST11. Use a 5-mm nut driver to remove standoff nuts ST4-ST9 and
a 6-mm nut driver for ST10 and ST11.
If the threads on the two hinge blocks are damaged, the I/O panel bracket
will have to be replaced.
