Circuit diagram for the Intel-based HP Pavilion dv7t, drawn on the Compal LA-4082P board. The project is named VADER and this is the discrete-graphics variant, revision 0.4. Compal uses the LA-xxxxP pattern for its laptop mainboards, and the same model can ship with UMA or discrete boards, so confirm the LA number and revision printed on the PCB before you rely on it. Use the PDF to trace power sequencing, locate the GPU supply rails, follow signals between sheets and find test points when diagnosing a dead or no-video board.
