Schematic in PDF form for the Lenovo E41-25 laptop, drawn for the Compal LA-F971P mainboard, delivered as a 1.05 MB RAR archive. LA-xxxxP numbers are Compal's board identifiers, and the same platform may appear under several model names. The circuit diagram lets you follow power sequencing, check rail voltages, identify the PWM controllers and trace signals between the CPU, charger and connectors. Make sure the board carries the LA-F971P marking before using it, since a different revision can alter component values.
