    What causes the Surface Pro 2 to sometimes not go to sleep and then just run hot and have the fan kick on? Twice I've went back to my Surface Pro 2 and it was it and the fan was running. I had powered it off (set to sleep) and closed the cover before this happened. Runaway app?

    open up task manager and take a look at what apps you have open.

    you can see which apps are using up cpu power.

    Yeah, I tried that...nothing was taking up CPU yet it was hot and fan was running. My original Pro did this from time to time. :(

    Sounds like putting the system to sleep, fails, and a bug makes the SP2 CPU loose all power management system.
    (I don't have any Surface product yet, so I can't test anything)

    You can diagnose the sleep system of Windows by simply:
    -> Open the command prompt as Administrator (Win+X > select: Command prompt (Admin)).
    Then type: cd c:\, hit ENTER
    Then type: powercfg -energy, hit ENTER

    Am HTML report will be generated in C:\
    Have a look.
