MSI MS-16881 schematic, revision 1.1 as shown by the -11 suffix, supplied as a PDF inside a RAR archive. It covers the circuit design of the board used in MSI notebooks such as the CX620. Technicians use it to check voltage rails, follow signals between the chipset and the EC, and measure components while diagnosing faults. Make sure the board says rev 1.1, because revisions 1.0, 2.0, 0A and 0B differ in some details.
