Circuit schematic for the Lenovo E41-55 laptop, motherboard LA-K111P at revision 1.0, supplied as a 1.22 MB PDF. The LA-xxxxP pattern belongs to Compal, the ODM that designed the board. Use the diagram to follow power rails from the adapter input through the charger and regulators, look up component values and see how the EC controls power-on. Any PDF reader opens it, and searching net names speeds things up. Match the LA number and revision on the PCB before trusting part values.
