Not on the 190 or the 5300, the socket is soldered directly to the logic board. A very common failure is loose solder joints causing a lack of power. I've had to resolder my 190 and all three of my 5300s.
The 5300's got a separate DC power module that connects the battery to the logic board, in the opposite corner of the machine from the power socket. I can't remember what the 190's got, it's so long since I've been inside it. It's like a simplified 5300, I seem to remember the DC converter for the battery is actually part of the 190's logic board instead.
