i have an i5 256gb with gpu keyboard. i have updated whatever needs updating through the windows update. i am just surfing the net with chrome with mail and small apps open and the surface book just hangs will not respond to any keyboard press or the mouse or the touchscreen. not even control alt delete. I have to long press the power button to turn it off to be able to use it again. I also tried removing the screen but it won't let me. Any idea whats going on? anyone experiencing this as well?
