Schematic set in RAR form for HP Compaq 540, 6520s and 6720s notebooks, designed by Inventec, with DDD in the name, which likely refers to Inventec's internal platform code, and UMA indicating the integrated graphics version. The discrete-GPU variant would use a different circuit, so confirm your board has no dedicated graphics chip. At 808 KB, the archive holds the PDF diagrams used to trace power rails, locate test points and check signals around a short. Match the Inventec board number on the PCB before relying on it.
