Sony VGN-C22CH mainboard schematic tagged with the platform code MS60, delivered as an 881 KB PDF. The extra word imp in the name is not explained and may simply be an uploader tag. Matching size with another VGN-C22CH schematic suggests both files carry the same drawing. Use it to trace voltage rails, inspect the embedded controller and charging circuit, locate parts around a shorted line and verify connector pinouts. Revision is not stated, so compare the MS60 code and the revision on the PCB with the title block.
