Schematic for the MSI MS-1637A launch board at revision 2.0, a 45 KB PDF. A launch board is the small daughterboard that usually carries the power button and related indicator or quick-launch circuitry in the notebook. With this sheet a technician can check the power switch signal path, LED supplies and the connector pinout to the main board when a laptop will not turn on from the button. MSI uses MS-16xx numbering for notebooks; match the subboard marking and revision before use.
