Any lower-power rating will cause the charger to stop/bug when the charge starts.

You can also hook it to a modified ATX power supply (standard Computer PSU since 1998).
To do so, you need to wire your charger on the BLACK and YELLOW wires, and jump (with a paper clip or twist if you don't mind cutting the wires) the GREEN and BLACK wires from the 20/24pins connector.

For long term operation, it is best to add a 10W 10ohm ceramic resistor bolted to the metal case and wired between the RED and BLACK wires. This will help with keeping a more stable 12V supply (because of the way the ATX PSU work). Careful as the resistor might become hot.

A cheap/old 350W is plenty enough for 10+ Amps.

What are the exact specs of your laptop adapter? For example, if it states 18v 3.4A, as long as you keep the charge rate under 3A it should work.
I can't recall the exact specs of that laptop charger (not home right now but will check when I get home).

I did find another laptop charger at work and it is 18.5v 3.5A... I read that it should work... i guess I'll find out once I get home.

Also the B6 manual states that it can take 11~18V and max 5A... But I also looked up that there are some 18.5v 3.5A power supplies that work for the B6... so really it should work. Crossing my fingers.
