Schematic in PDF form for the HP 440 G2, made on Compal board LA-B181P at revision 0.5, supplied inside an 882 KB RAR archive. Compal LA- numbers are the ODM code silk-screened on the motherboard, so check that the board in hand reads LA-B181P before trusting part references. A technician opens it in any PDF reader to follow power rails, the power-on sequence, charger and EC signals, and to identify which components sit on a shorted line. Note that an early 0.5 revision may differ in small details from production boards.
