Hi, I have a quick question about the start up about the surface pro 4. When I bought the device yesterday I simply clicked the power button and it simply turned on. I did the set up and went to work. When I got home once again I simply pressed the power button and it turned on. I used it for a couple hours and no problem. Then after a couple of hours without using it I went to press the button and nothing, it doesn't turn on. Now I have to hold the power button down for like 30-45 seconds then it powers up. Once its powered up I can then press the power button to turn it on and off. So simply put after a couple hours of the surface pro 4 not in use I have the hold down the power until it turns on. Is this normal? Any advice will be very much appreciated. Thanks.
