Circuit diagram for the Quanta RD2 board at revision 1A, stored as a PDF of about 674 KB. RD2 follows Quanta's ODM project numbering, used on motherboards that end up in laptops of various brands. Repair technicians use such a schematic to trace power rails, follow signals from the EC and charger, measure expected voltages at test points and isolate parts causing a short. A standard PDF reader opens it. Make sure the code and revision printed on the PCB match RD2 rev 1A before relying on component values.
