Circuit diagram for the Quanta ZH1 board project, a 852 KB PDF with no revision indicated. Quanta designs notebook mainboards as an ODM and labels them with project codes such as ZH1, printed on the PCB itself. The schematic is useful for following power sequencing, tracing signals from connectors to the chipset and identifying components on a shorted rail. It opens in any PDF reader. Before relying on it, confirm the revision in the title block matches the one silkscreened on your board.
