HP ProBook 4326S laptop boardview for the Quanta-designed mainboard SX7, discrete graphics version (DIS), revision E, in BRD format at 288 KB. Quanta is the ODM behind this board, and its project codes like SX7 identify the design rather than the HP model. The view shows component locations and net connections for tracing power rails, locating test points and checking shorts on the motherboard. Open it with OpenBoardView or FlexBV, and make sure the PCB carries the same SX7 code, DIS variant and revision.
