I got a broken MBP here. The PSU-LED is on green when connected and the orange when the battery is connected. So it is charging. Now when I press the power button or shortage the Power-On-Pads on the logicboard, the fan starts to rotate for a split second. Looks like the power immediately breaking down.
I just downloaded the schematics and the brd-file of the board.
Are there some known issues whit that board? This behaviour look familiar, the 17" 2008 and 2009 had this also whit the C7771 Cap which powered the GPU, but the 13" does not have a dedicated GPU.
What could it be? What to measure next?
