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?

Since the February 17th updates, the battery drain while shutdown is significantly less, but inconsistent. After about 12 hours being shutdown, usually both batteries are at 100%. Sometimes on battery is at 97%, sometimes the other. Once or twice both have had a 1-3% drain. Since I don't use sleep or hibernate, that's not an issue for me. I can live with this, but personally I believe there shouldn't be any drain at all, even after a week or more.
Turning off fastboot doesn't help. I "shut down" for about 5 hours and the battery drained about 3% I will try to hibernate tonight and see if there are differences. I will also try the uninstall battery driver and restart method.

Surface Book and Surface Pro 4 are pretty much the same machine, so if you have either of those you can troubleshoot same way. SP3 is a different beast all together. Has a different cooling system and chip set. Turn off Fast Startup and most of not all issues should be resolved. Battery remains an issue for everyone, but this will fix Hello camera issues and waking from sleep for some.
Go back through this thread as there are several things you can try although most seems to be for surface book. as an example uninstall device drivers for battery (don't delete) and restart to refresh. Try a re set, or get on support and they will walk you through.
