Circuit schematic for the ASUS K53U built on the Compal LA-7322P motherboard, revision 1.0, in PDF form. The LA-xxxxP pattern is Compal's board numbering, so Compal acted as ODM for this ASUS model. Use the sheets to follow power rails from the DC jack, check charger and regulator circuits, trace signal lines and find the part responsible for a short. It opens in any PDF reader. Make sure the LA-7322P code and revision on the PCB match, because the neighbouring LA-7321P is a different board.
