Any idea where the power on pads are ?

I did not need to remove the heat sink. You can simply remove part of the fan assembly in about 1 minute and the heat sink and its associated arm with fins comes right out. Removing the heat sink introduces unnecessary complications that could destroy your logic board should you perform an incorrect repair on the thermal paste.
Any instructions and images demonstrating this?
