surface book battery drain while shut down

Yes, I too was very disappointed with the problems I had with my Surface Book in the beginning. I got the i7/16GB/512GB model and after buying the Microsoft Complete support package, a nice courier bag and a spare pen, I spent over $3,500 in the Microsoft Store that day.

My main problems in the beginning were the crashing Graphics Driver and Sleep/Hibernate being non-functional. I was also not pleased with how my touchpad was sensitive only on the left side for touch-tapping. 

I've never had a problem with my USB ports. The caveat is that the only thing I've ever used USB for is my Windows 10 backups. I use a Seagate Backup Plus Portable Drive model SRD00F1 and it's worked flawlessly since the beginning. I do understand that the Surface Book USB ports deliver low power and have difficulty with peripherals that require higher power.

My Graphics Driver crashing was fixed last year and I've not had a problem since. My Sleep/Hibernate problem was solved with the June 20th update and I've not had a problem since. And my touchpad sensitivity problem was fixed with the Anniversary Update. At this point in time my Surface Book is running problem free.

I've never tried to see how much battery just the sleep portion uses as I could care less. While on battery, as long as I have enough battery to get me through a long workday when out of my office, I'm more than satisfied. 

What kind of sleep battery drain are you experiencing? Can your Surface Book not get you through an entire workday using only battery power?

My SB  still drains way to much battery in sleep. I have all the updates and even tried reinstalling windows from scratch. I have also have very unstable USB connection. Early adopter or not you expect something costs over $2000 work properly. Microsoft should have recalled those SB that are not working properly, offer free repair or exchange. If the same thing happens to your car, you'd expect the manufacture to do that. But MS is too cheap, and probably too "big" to care a few "early adopters".

You managed to pick out a post I made 9 months ago for a comment? The state of the operating system has changed quite a bit from that time. 

Nine months ago connected standby was not working the way it should and I was getting no battery drain while completely turned off. I had to totally shut down overnight back then because Sleep/Hibernate didn't work at all.

Since the June 20th update Sleep/Hibernate is working like it should and connected standby is working like it should. I no longer totally shut down and Sleep/Hibernate is now reliable. There is a small battery drain while sleeping, just as there should be during connected standby. At this point in time I can easily get through a work day when away from my office and on battery.

I'm sorry you are having problems. Being an early adopter, from the day the Surface Book was first released, I've gone through the same frustrations as everyone else. Today my Surface Book is finally working the way it should have when I first got it.

No, I don't work for Microsoft.

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.

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.
