Quanta JM5B laptop motherboard schematic, revision 3A, stored as a 1.19 MB PDF. The name gives only the ODM project code and revision, with no retail model or chipset. Quanta builds boards for many brands, so match the JM5B code and revision printed on the PCB, since earlier revisions may use different parts. Use the schematic to trace standby and main rails, follow the power-on sequence, locate the components behind a short and identify signal names for measurements at connectors and test points.
