Pops out of sleep when (dis)connecting the charger

Happens to me too. I find that if you just let it go back to sleep by itself, there's a high chance that it won't actually go to sleep and will instead burn through a lot of your battery, possibly getting very hot inside of a bag. I always disconnect the charger before putting it to sleep to avoid this.

And I just inadvertently tested what I said by unplugging it while it was asleep at my desk which woke it up and then pressing the power button to put it back to sleep. It burned through 15% of my battery during the 40 minute commute back home.
If you happen to wake it up from sleep by unplugging it, what I find works is to log back in so that you get to your desktop and then press the sleep button from there. I wonder if this happens because Windows doesn't flip the, in basic terms, sleep flag such that it still thinks it's asleep even though unplugging it woke it up which prevents it from automatically going to sleep after a period of inactivity.

Yup I have this problem too and it's annoying. When I undock it I need to treat my SP4 like a newborn infant, letting it sit for a min listening to hear if the fan comes on. If I open the lid I think that may un-sleep it too, not sure. If I breathe within 10 feet it also may turn on the tablet 
So many times I put the laptop to sleep and then in my backpack only to hear that familiar hissing snake sound coming out of my significantly warmer backpack and significantly reduced battery. I mostly just hibernate it now. My android tablet which is $1500 cheaper works better in this regard. Frustrating.
