Schematic for the Quanta ZAAR motherboard at revision 3A, a 3.29 MB PDF. ZAAR is a Quanta project code, and the name does not say which laptop brand or model uses the board. Read the title block or match the DA-prefixed number on the PCB to identify compatible machines. Technicians use such diagrams to follow power rails, check the startup sequence and find which part shorts a supply line. Make sure your board is revision 3A, since component values can change between revisions.
