PDF schematic covering the USB daughterboard of the NB8513 design, revision V3, roughly 2.15 MB. Rather than the main logic board, it documents the small USB board, typically including the port connectors, current-limit or power switches and the cable connector back to the mainboard. It is useful when a USB port has no power, a port is shorted, or the interconnect cable is suspected. The name gives no laptop brand or model, so compare the board number and V3 revision printed on the small PCB with this document before working from it.
