Wistron-designed schematic for the HP Pavilion dv2000 and the Compaq Presario V3000, which share a mainboard design, provided as a 1.00 MB PDF. Technicians use it to trace DC-in and charging circuits, system power rails, the power-on sequence and graphics power on these notebooks. Both series came in several chipset and GPU variants, so check that the board on the bench matches the version covered. Wistron is the ODM behind many HP laptops. Any PDF reader handles the file.
