Early-revision schematic for the Lenovo G585, drawn for the Compal LA-8581P board at revision 0.1, in a 1.95 MB PDF file. A separate revision 1.0 drawing of the same board exists, and an 0.1 version may show prototype values or parts that changed later, so match the revision on the PCB. The LA-xxxxP code is Compal's own board numbering. Any PDF reader opens it for searching nets, following power sequencing signals and identifying the components behind a dead or shorted rail.
