Have Tos satellite myself

Does it still charge batt when ac adapter plugged in?

If so I wouldn't go to expense of repair as I guess you're out of Warranty...you might want to gerryrig a "new" AC supply to the prongs of the batt terminals at the laptop or try an identical supply . Sounds like something in the internals of the Tos but buying a new batt would seem a better deal than paying labor charges
