Technicians frequently use the LA-E801P Rev 2.0 schematic to resolve several recurring motherboard faults:
Verify if 19V is passing through the first and second MOSFETs (e.g., PQA1). lae801p rev 20 schematic better
Repairing a Rev 2.0 board using a Rev 1.0 schematic can be misleading. Manufacturers often tweak the or swap out proprietary PWM controllers between revisions. The Rev 2.0 diagram ensures you are measuring the correct test points and referencing the exact part numbers for surface-mount components. Technicians frequently use the LA-E801P Rev 2
