Hey guys, this is a little embarrassing because I consider myself somewhat technical; however with all these updates going on for the Surface Pro 2, I have noticed over the past month that whenever I close the touch cover and place it in my sleeve, upon pulling it out hours later, the battery is down and the unit feels very warm. Today I shut the cover and when I pulled it back out 30 minutes later, the screen was dim and the screensaver was running. I haven't screwed around with the sleep/hibernation settings when the cover is closed, so I am wondering why it's not going to sleep fully.
