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.
