Motherboard schematic in PDF form for the 1000HE, a netbook model, as indicated by the MB tag; the file is 696 KB and gives no board revision or brand in its name. Any PDF viewer opens it. The diagrams help a technician trace power rails, check the charging and sequencing circuits, follow signal paths and locate components while diagnosing faults such as no power or a short to ground. Compare the board number printed on the PCB with the schematic title block to confirm the correct revision.
