surface pro power problems
I have a surface pro 3. It’s gorgeous and I love it. However sometimes it gets confused and does not start up. I use this page to help me.
When it does start, I notice that the clock has lost some minutes / hours (basically since it was last working). So remember to update that.
Recently on the new patches for win8.1, it seems to power down rather than sleep. I have not quite figured that one out yet.
This is a useful info page on power states and InstantGo. And also windows club.
