Circuit diagram for the Quanta LV6 notebook mainboard, a 5.45 MB PDF. No revision, laptop brand or model is stated in the name, only the Quanta project code. Quanta is an ODM that manufactures boards for several laptop brands and marks them with codes such as LV6, usually printed on the PCB together with a revision letter. Any PDF reader opens the file. It is useful for checking voltage regulators, charger circuitry and signal paths, but check the board marking first, since different revisions can differ in parts and layout.
