Schematic for the Sony VAIO VGN-SR55E, mainboard MBX-190 with the M750 project code, provided as an 878 KB RAR file. After extraction the diagrams open in a standard PDF viewer and let you trace power rails, check the charging and standby circuits and find component values for a faulty section. The name gives no revision, so compare the MBX-190 label and revision printed on the PCB with the title block in the drawings before relying on any part numbers.
