Not sure what you mean by 'crash', but mine often just won't turn back on. I have to do that key-combo (I think it's simultaneously holding the volume-up and power key) until I see the Surface logo and it reboots. Very annoying, and definitely a stark contrast to what my experience was with an iPad -- it always turned on as expected when I hit the power switch. I only mention it as I just got a SP2, previously used an iPad. I also miss being able to hit the power switch just to black out the screen, my laptop has a key-combo to achieve that as well, but my Surface doesn't =(
Not sure this is exactly what you mean, but go to Control Panel - Power Options (or get there by the battery icon on the tray). There's an option labeled "Choose what the power button does", click it and the next dialog has settings you want, including initiating sleep state on pressing the power button.
At least it does work that way on my SP2...
This is an old problem that my SP2 has had since Day One, prior to the bogus December firmware update. In my case the only clue to be found in Event Viewer are unexpected restarts - but the timestamps ALWAYS corresponded with when I pushed the power button to wake it, not when it went to sleep. On the MS forums some people call this the "black screen of death". It appears to primarily (exclusively?) affect the 256GB and 512GB models (mine is 256GB)
My "fix" has been to configure the SP2 so it always goes into hibernate instead of sleep. That has worked flawlessly for me ... until a couple of days ago. Now inexplicably if I don't touch it and let it time out it won't always successfully hibernate - either it will sit there idle with display off (i.e. not sleeping) or *appear* to hibernate and then crash when I hit the power button. I'm going to keep it configured to hibernate since it is the less evil solution - I routinely had 4-5 crashes a day prior so this is still an improvement
I am having this exact issue and so are others.
Not every time, but occasionally when I try to wake the computer the fan runs for a few seconds and the computer crashes. If you look at the event viewer, under system you can see events related to the crash.
I am awaiting the January firmware to see if it fixes it, otherwise I am returning the surface pro 2.
