About this task
NOTE: Before removing the base cover, ensure that there is no SD card installed in the SD card slot on your computer.
NOTE: The system board can be removed and installed along with the heat sink, when you replace the palm-rest and
keyboard assembly. This simplifies the removal and installation procedure and also prevents damage to the thermal bond
between the system board and heat sink.
