Figure 4-31. Processor Board Removal
Remove the processor board from the main board.
The processor board is held in place on the main board by connectors JP18 and
JP19. Using the fingers of one hand, gently remove the processor board from
the main board by pulling straight up. Do not rock the processor board to
remove it. This may damage the two connectors on the processor board or the
main board.
There is a rubber bumper on the upper right corner of the processor board. The
bumper assists in keeping the processor board in place. If you install a replace-
ment processor board, be sure to apply a bumper in that corner of the processor
board. Also, there is heat-sink thermal pad on top of the microprocessor and this
may need to be reinstalled.
When reinstalling the Inspiron M166ST, M200ST, M233ST, or M233XT pro-
cessor board, press down on the white dot on top of the board. The white dot
indicates the best spot to apply pressure to seat the processor correctly on con-
nectors JP18 and JP19. (White dot references on the Inspiron D233ST,
D233XT, and D266XT processor boards are not necessary.)
