Quanta ZH3 motherboard schematic package, revision D, covering two board numbers: DA0ZH3MB8D8 and DA0ZH3MB8E6. The 1.13 MB RAR does not state the laptop model. Quanta DA0 part numbers identify the bare PCB, and the trailing characters differ between PCB versions, which is why both variants are listed. Compare the number printed on your board with these two before using the files to follow power rails, check signal paths or locate test points while diagnosing a dead or shorted board.
