About this task
NOTE: When removing the system board to replace/access other parts, the system board can be removed and installed
with the heat sink attached in order to simplify the procedure and preserve the thermal bond between the system board
and heat-sink. In order to do so, you must remove the two M2x3 screws securing the fan to the palm rest.
The following images indicate the location of the system board and provide a visual representation of the removal procedure.
