Hello,
this 820-494 is dead after the customer swapped a faulty trackpad cable. He did not removed the battery and as he want to plug it in he saw a spark on J4802 (the corrosponding connector at the trackpad - not at the board). So i guess he shorted PPVIN_S4_Tpad to GND. Now its dead and missing PM_SLP_S5_L and i dont really know where to start. The first missing rail is PP5V_S4 not enabled by PM_SLP_S5_L...
