A BUNCH of cool stuff for sale! , Need a couple extra bucks for Christmas.
It about the average you could expect out of a laptop.
if you have it on power saver mode and your not doing a bunch of movie watching/video games ect...ect... it would probably go 4 or 5 hours.
But if you leave it on regular power mode and watch alot of movies and what not I would say maybe 2 or 2.5 hours or so.
