13. Lift the system board assembly out of the bottom case assembly.
Be sure to transfer the memory module(s) to the replacement system board
assembly. If you are replacing the thermal cooling assembly with a new one,
remove any lining present on the thermal pad before installing the new thermal
cooling assembly.
After replacing the system board assembly, be sure to enter the system's service
tag number into the BIOS of the replacement system board assembly. Insert the
diskette that accompanied the replacement system board assembly into the
diskette drive, and turn on the computer. Follow the instructions on the display.
When you reinstall the microprocessor module in the system board, make sure
you press down evenly at all four corners of the module. When the
microprocessor module is seated, all four corners must be at the same height. If
one or more corners of the module are higher than the others, the module is not
seated correctly. To ensure the microprocessor module is seated correctly, look
at the holes on the processor-module fence. You should see no less than the top
half of the holes all the way around the microprocessor module (see Figure 28).
Install the three screws to secure the microprocessor module to the system
board. Place a new processor hold-down clip (either a one-slot or two-slot clip)
over the corner of the fence as shown in Figure 28. Press the clip down to lock it
in place. Do not reuse the old clip.
