Laptop schematic in PDF form for the Compal LA-3111P mainboard, with HDL10 and 401408 also appearing in the name, likely the project code and a document number. The LA-xxxxP pattern is Compal's ODM numbering, used in notebooks sold under brands such as Dell, Acer, Toshiba and Lenovo. The diagram helps trace power rails, charger and EC circuitry and signal paths when measuring for shorts or missing voltages. Check that LA-3111P and the revision on the PCB match the document before following its values.
