PDF schematic, 1.55 MB, covering Lenovo board LA-C582P at revision 1.0 (R10 in the name). The number follows Compal's LA-xxxxP scheme, as Compal is the ODM that built this Lenovo board. Use the circuit diagrams to trace rails, check the power-on sequence, and identify parts around a shorted line. Searching net names in a PDF viewer speeds this up. A revision 02 version is also available, so read the revision on the PCB silkscreen before relying on component values or connections.
