Looks like you've got a T3x power supply (or even older). Having 
upgraded through this route I have both power supplies and the T41 
worked fine with the lower output PSU except for the screen flickering 
during heavy disk access. It still charges the battery effectively (and 
there's obviously no problem if you're on battery power alone). I 
wouldn't worry about it too much unless the flickering becomes 
irritating, and you can always get a universal PSU of the right output 
later.
