Compal schematic for the LA-7491P laptop motherboard, revision 1.0, packed into a compact 602 KB RAR file. The small size suggests a single PDF of the diagram, though contents are not listed in the name. Such a document lets you follow each power rail, find its regulator and enable signals, and trace data lines when a port or device stops working. LA-xxxxP is the numbering style of Compal, an ODM supplying several laptop brands. Make sure the board label matches LA-7491P before working from these pages.
