I do some searching on bypassing the "smart power plug" and there are some people suggesting that it has been done just to wire in a 2K resistor to the positive side and a capacitor to the negative and feed that into the white wire. Apparently, that white wire wants something like 12-13V.
This is not always the case. Some of those smart power supplies have a one wire communication chip that sends an actual digital code the laptop/PC is looking for.

At any rate, this car charger will probably work. It's listed as compatible with the same laptops that your stock charger is compatible with.

It has to be a boost charger of some sort, though there isn't a guarantee of how low an input voltage it'll work with. Still $20 for a potential off the shelf solution seems reasonable to me.
