HP 340 G3 laptop motherboard documentation for Inventec board 6050A2811101, revision A01, in a 1.95 MB RAR archive. The name marks the content as PDF, so it is likely a schematic or printed layout rather than an interactive boardview. Inventec designs boards under the 6050A numbering, with -MB-A01 giving the assembly revision. Use the diagrams to trace power rails, the EC and charger circuit, and the signal paths behind no-power or no-display faults. Confirm the board sticker matches before relying on it.
