show more plans...
Yeah I've tried high performance and whatnot, it just isn't going to work the same on battery I've realized--its a pretty high-end notebook. I think I'll go ahead and try to find a car & plane adapter to make do, since I really only need battery for plane rides and such.
I actually found one: Kensington K33197 120W Auto/Air Ultra Portable Notebook PC Power Adapter
Though I'm not sure it'll work with my laptop. Do you know if it will given the specs? Thanks for all the help by the way--after I figure this out I'll be good.
