Compressed package for the Quanta UM7B mainboard, the QD prefix being the usual Quanta designation, in an Intel version with discrete graphics (DIS).

No laptop brand or board revision appears in the name, so compare the project code and revision printed on the PCB before relying on it. Extract it with WinRAR or 7-Zip, then use a PDF viewer to follow nets, find components and locate test points.
