Schematic in PDF form for a board labelled Rams with the code 0P20P2A and the FT4 R17M tags. The name gives no laptop brand or model, so identify the board by matching these codes to markings on the PCB. The 2.81 MB RAR opens with any archiver, then a PDF viewer. A schematic is used to follow power rails, find the enable chain and check components around a short. Treat values carefully until the revision on the board has been confirmed.
