Looking at a board that started out with quarter fan spin, I noticed that there was a glob of smeared thermal paste by U7201, I cleaned that and found that the thermal paste was now bridging most of the pads on one side of the QFN. I removed U7201 with the plan of cleaning the under area and replacing. I found several oxidized pads and 2 that were blown. Now the board gets a green light and then after a while sitting with the magsafe connected or trying to power it on with the power on pads the green lights cuts off.
