Surface Pro 2 Not Sleeping and Then Running Hot

[garak0410]

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.

something doesn't sound right
the fans on my SP2 are yet to kick in
..and I've been stressing it a bit, running games and such

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
