I am not sure what laptop you have. The Mosfet AO4407 in Dell Compaq/HP laptop is part of the charging circuit. So I would further investigate if you have some capacitor issues that caused the Mosfet to short circuit. It's 'fuller' part# is AO4407 If you look it up at Mouser.com, it cross referenced to a chip from ST micro: STS10PF30L. they are readily available. Here is the datasheet http://www.aosmd.com/pdfs/datasheet/AO44... good luck, and may be consider a surge protector in the future...who knows :)

Sounds to me that you have a short circuit in the charging circuit. Also make sure that the laptop is cooling okay. Just wondering if you can use a different power supply just in case the one you are using is having power surges. Here is a little bit more info on the AO4407 http://mayohardware.blogspot.com/2010/04... not the same computer but the same application.
