    Microsoft Surface Laptop 1868 short

    Is there a schematic anywhere so I can find the value of the capacitor circled blue in the first picture? There are no more shorts in this area after removing it but still no voltage anywhere on the board.

    I had to replace the battery since it was leaking acid near the bottom. With the old battery it was drawing 0.03A but with the new one its 0.00A

    Thanks for any help

    Review the datasheet for the MPS brand regulator with the AUH topside markings. With no power, measure the resistance from the trace pads to the ic and use the recommended parts from their reference design. Essentially, locate from the reference schematic as to which part is missing.
