surface book battery drain while shut down

Split from this thread.

I have been noticing that when I shutdown my surface book, when I power it on the next day the battery has drained some. If I leave it off for a couple of days it will drain down from 100% to around 85% or lower.

I disabled fast startup... and then just decided to disable hibernation altogether. That didn't help.

I have windows hello disabled, but that shouldn't matter anyway since I'm shutting it down, not sleeping.

Some searching and I found a general windows 10 issue with the "Intel Management Engine Interface" driver. Some say that v11 can cause this issue. One solution that I have seen suggested is to go into device manager and in the power management tab for this device uncheck the option that allows windows to power it down to save power. I tried that and it didn't help.

Others have suggested downgrading the driver from v11 to v9 or v10, but I don't know where to get v9 or v10 of this driver that is compatible with the surface book. Anyone know if one of the downloads on Intel's site would be compatible?

So, has anyone else noticed this issue and know of a fix?

    Looks like the battery drain issue has resolved itself with the last update.  It did create two other issues though.  The task bar showed the screen was detached whether it was or not, and the front camera quit coming on during sign it.

    I got updates today that solved the new problems, I only hope they didn't recreate the drain problem.  I will discharge, recharge and shut off to see where we are on that, and report back. 

    BTW I have the I& 16GB 512 MB machine and I have not had the instability problems, but I do not use hibernate or sleep, I just shut down, so I cannot offer any help on those issues.

    The 3/1/16 Windows updates are said to address, among other things, these items:

    "Windows Update installation, startup . . . resuming from hibernation, shutdown, kernel, Start menu, storage, Windows Hello, display modes".

    Ok, mixed news.  After applying the late Feb update, battery drain seemed to resolve itself.  Created the detached problem and the front camera problem when using Hello.  Mar 1 update fixed those two items, but when rebooted they reappeared.  Did the whole discharge and recharge deal again, and after 25 hours shutdown and unplugged battery one went to 96.4% and batt 2 stayed at 100%.  Looks like we are back to the drawing board.  I will fill let you know what I find out.
