surface book battery drain while shut down

Do you work for Microsoft?  It's great that your  Surface is running so well but you're experience is frustrating, unhelpful, and irrelevant to those of us who are having the issue.

After 10 months of trying to work around the issues on my Surface Book I have finally decided that enough is enough. Microsoft either cannot fix the problems on this device or doesn't care to. The overheating problem is gone, thankfully, but battery drain problem still exists. I unplugged in from my power adapter at work on Friday evening, put it to sleep and when I opened it Monday morning it did not have enough power to wake up. When I plugged it in and started it up the system had completely shut down (all apps were closed). Couple this with the fact that I can no longer plug in an external display and I am done. I've installed every update hoping that each will be the one that finally returns two of the most important capabilities back to my machine (I used to be able to use an external display and the battery life used to be decent - never as good as advertised). So I am done. I am fortunate that my employer will buy me a new machine because my productivity is important to them. I genuinely feel badly for having asked them to take a chance by buying me an unproven machine and then getting burned (thankfully not literally though some of the #hotbags I experienced felt like they were scary close to that) by the decision. I'm going back to a Lenovo because I know they work as advertised. Good riddance Microsoft. May this entire debacle hasten your decision to get out of the hardware business where you have no business being.

It still happens me from time to time before and after the all the latest patches and the Window Anniversary update. And I think it could be due to some user errors. Sometimes while the SB is being shut down and just before the book is completely off, I accidentally touch the power button during folding it up or putting into my case cover, this I believe prevents the SB from shutting down completely, in other words it may cause it to stay awake!

So just make sure you need to see the book is completely off by giving it a few more seconds before slipping it to your case cover or putting it away.

My Surface Book (i7, GPU 512GB) has gone back and forth between sleeping and not sleeping as various updates have been applied.  Some updates fix the problem and then later another will break it again.  However, everything seems to be working perfectly since the Anniversary update.  I'm optimistic this might be the end of the issue.

I should add, though, that this doesn't prevent it from sometimes getting a little warm even when it's sleeping, nor from using up some of the battery while it's sleeping.  But I haven't seen it lose more than 6% of battery while sleeping since the update.  That's not a problem for me, especially if I'm getting background updates and backups and so on for that 6%.

I replied on July 12 that after applying all system upgrades and patches, the problem on my surface book is solved.  If you just bought yours you likely need to update it.  If that doesn't work ms support is aware of the problem and may be able to walk you through it.  Again, I have a surface book, not a surface pro.
