IBM P/N 66G9984, FRU P/N 84G4359. "CAR Adapter", Input: 12V 5A, output 20-10V 2.00-2.20 A About 6" long, 1 3/4" wide and 1 3/8" deep with 2 cords attached - one for the cigarette lighter and the other for the tp power plug (4 pin). Seems to work fine with my 755CX - charges the battery while running the TP. Don't remember how much it cost but it didn't seem out bounds.
