Clean off the crud from the XDP connector pads, it is above the SMC. Also what happens if you normally power on?

I cleaned all the board inclusive the XDP pads but no luck, when power normally the fan spin like a millimetre and stops and as mentioned it runs in full power only when pressed power long and inserting power cable.
