Schematic or service package for the Quanta AT3U board at revision 2A, used in the HP V6500 notebook series, packed in a 1.04 MB RAR archive. Quanta is an ODM that designs and builds boards for HP, which is why the board code differs from the retail model name. Technicians rely on this kind of file to follow power sequencing, check rails for shorts and find components. Confirm that the PCB carries the AT3U marking and revision 2A, as other revisions may differ in layout.
