Schematic in PDF form for the Lenovo IdeaPad S400 Touch, Compal board LA-8952P at the PR01 stage. Compal's LA-xxxxP numbering covers many brands, including Lenovo IdeaPad models of this era. Use it to follow power rails, check charging and power-on circuits, and locate components and test points. Any PDF viewer opens it. The touch model uses a different board from the plain S400, so confirm the LA-8952P number and revision on the PCB before relying on it.
