Quanta schematic covering projects LZ2 and LZ2A, as a PDF in a 1.29 MB RAR archive. The name gives no laptop brand, board number or revision, only the Quanta project codes, so check the codes printed on the PCB before working from it. Laptop schematics like this are used to trace the charger and main rails, follow power-good and enable signals, check the EC and BIOS flash wiring, and find the faulty parts behind a short or a no-power fault. Any PDF reader opens the file after extraction.
