So I have my power button set to put my SP 3 to sleep when pressed. I finished work for the day, pressed the power button, and the screen went dark as it always does after pressing the power button. I placed my SP 3 in my laptop back and prepared for my trip back to the hotel (I am a consultant and travel M-F for work) Got back to the hotel and went to take out my SP 3 to do a little more work. The fan was on, the device was very warm (Not hot thankfully), but the screen was off. What would cause this? I thought when it was asleep that there were no processes running and the only thing that had power was the memory?
