Quanta BLBD schematic, a 973 KB PDF. The name holds only this code, with no revision or laptop model, and the exact meaning of the BLBD suffix is not stated, so it could be a main or sub-board within a BL-series design. Check that the code printed on the PCB matches before using it. Quanta builds boards for many notebook brands. The diagram helps trace power and signal nets, locate the parts on a shorted line and read connector pinouts between boards.
