Battery Issues

[winston smith]

I have a Surface Pro 2. It's a really great solution with the expected Microsoft disappointments. One of those is that I can go to bed with an almost full battery, having put the surface into Sleep, only to wake up to a dead battery. Can anyone help me understand why this is happening and what I can do about it?

Just read an earlier post and understand this should be fixed in a patch released in mid Jan.
