Circuit diagram from Quanta for project ZRQ, revision 3A, delivered as a 1.05 MB PDF. No laptop brand or model is stated, so match it by the ZRQ code, which on Quanta boards normally appears inside the DA0ZRQ board number on the PCB. Repair staff use such schematics to trace standby and main power rails, follow the power-on sequence, identify MOSFETs and controllers, and work out where to measure when hunting a short. Any PDF reader opens it; confirm the PCB is marked revision 3A, since later revisions can differ.
