Hello everyone. I just got the surface today, (i5 256) and set it up with a few average programs that I use on my laptop video player messenger itunes torrent downloader normal stuff that you would use. well, after fully charging the surface to 100%, i decided to watch a downloaded 1080p movie Zero Dark Thirty in bedn that i played via micro SD. all programs were shut off, except the messenger app (it's called Line messenger) the brightness was reduced to around 30-40%, and raised to about 50-60% 2 hours into the movie. I was using headphones with the keyboard attached the entire movie was only about 2 hours and 30 minutes, but the surface shut down before the movie ended.. WTF?? This can't be normal can it? Please help! I was planning on using the surface as a note taking tool, but if I only get 2 hours, this can't be good Please help!
