surface book battery drain while shut down

Hi everyone,

i am running insider build 11082.  In the past few days, my entire machine drains whether it is sleeping, hibernating or shutting down. Three days in a row now I've tested this and if my machine is unplugged and in either one of those states the battery goes down to zero.

This is my second machine because why would a third machine make a difference.

This magnet thing might have legs. My SB always drains when powered off. The last wo nights the lid has been left open and I had no power loss in my batteries. I am going to experiment a little more and will post again.

So I was on another site reading about another user experience and discovered something that seemed impossible.

Apparently, this user said you can actually detach the screen when the SB is in full power down mode.  Completed shut down and attempted and guess what?  User is CORRECT.

Now, maybe I am late to the party with discovering that, but given that knowledge, it would seem this might be one of the bigger reasons we are seeing significant battery drain when fully powered off. 

As previous user said, "significant design flaw" seems to be appropriate wording.  How else can you detach the screen when it has no power?

It would certainly make sense that a computer could be powered up from a powered down situation by pressing a button, as this is how we turn a computer on.  It would then make sense to me that pressing the button to release the screen would turn battery power on, release the screen, and then turn battery power off again.  It would seem that there SHOULD be an insignificant battery depletion with the process to make the screen release and/or a screen reattachment.  Otherwise the battery should not be in use.  

I've tested my SB i7/16GB/512GB a number of times and before completely powering down at night I'm at 100% battery.  In the morning I'm at either 100% or 99%.  I've never had any more battery depletion overnight than that.

At 75% brightness I can get an average of 8 hours on battery.  At 50% brightness I can get an average of 12 hours on battery.

Until the "sleep" problem is resolved I'm totally powering down at night and I'm totally powering down before putting my SB in my commuter bag.  However during my work day I thoroughly enjoy using "sleep" and Windows Hello Face Recognition.

I get what you're saying in theory. However, from a powered down state, pressing the release button to detach the screen happens immediately. If it was fully powered off, you'd think in the least it would take 10 seconds or more to turn back on, in theory. . I suppose that to wouldn't need to fire fully back up to do so, but I suspect given what's been mentioned, this could be related.  

If you power down fully and don't lose power overnight, consider yourself fortunate. Many people are not as fortunate. What stinks more so that should never happen.  All these posts over the last month's prove what a total embarrassment this has become for MS. 

With the SB powered off I would think there would be no need for the computer to boot up.  All it should need to do is release the screen.  I would think that should happen instantly. Just my thinking.

It is my suspicion that many that are reporting power loss aren't really shutting down but are actually in "sleep".  If I put my SB in "sleep" I will, indeed, show a significant loss of battery overnight.  Microsoft has admitted here in the forum that "sleep" does not work as it should and will be fixed.

I fully powered my SB down last night and then removed the charging cable.  This morning I powered up and immediately went to the charging icon in the tray before attaching the power cable.  It showed 100% battery in both batteries and 100% total.

I do not power down by pushing the power button or by closing the lid as my default power setting would put my SB in to "sleep" mode.  I power down by:

Windows/Start -> Power -> Shut Down

I power down the same way you do.  Power->Shut Down.  Doesn't matter.  I lost 12% overnight doing it that way last night.  It's consistently losing 8-12% overnight following that method of powering off. 

There is something very different between our two machines.  

Mine is  i7/16GB/512GB, Lot # 1546, from Atlanta Microsoft Store, Nov 30, 2015.
