Laptop schematic for the BenQ Joybook A51E, in PDF format. The name gives neither the board maker nor a revision, so read the project code and version printed on the motherboard and compare them with the title block before relying on it. A schematic like this lets you follow the DC input and charging circuit, the standby and main system rails, the processor regulator and the embedded controller logic. Use it to measure rails in order, identify the parts on a shorted line and find test points when diagnosing no-power or no-boot faults.
