Schematic in PDF form for the Lenovo B590 laptop, designed by Wistron, with the project tag LA480 given in the name. Though LA-style numbers usually belong to Compal, here it is labelled as a Wistron design, so check the board marking. The 6.87 MB document shows the circuit diagrams needed to trace power rails, follow signals and identify component values around the charger, VRMs and power sequence. Compare the board number printed on your PCB with the schematic title block before following it.
