Quanta ZHNB schematic in a 2.6 MB PDF, with no board number, revision or laptop brand in the name. Its larger size suggests it may be a different or more complete edition than other ZHNB documents, but that is unconfirmed. Quanta boards carry a DA-prefixed code containing the project name, so verify that on the PCB before use. Use the drawing to trace power sequencing, regulator outputs and signal paths when chasing no-power or short faults. Any PDF viewer will open it.
