Archive for the Q502LA motherboard, revision 1.1, packed as a 122 KB RAR. Q502LA follows the Asus model style, but the name names no brand, so verify against the unit. The small size suggests boardview data rather than a full schematic, but extract it to check. A boardview lets you find components, follow nets and locate test points while chasing a short or missing voltage. Confirm the rev 1.1 marking on the PCB before trusting part positions.
