Battery drain overnight while shutdown

Lately, after I shutdown (full shutdown, not sleep or hibernate) my fully charged Surface Laptop 2 at night, I turn it on in the morning and find that the battery has lost around 25% power overnight! What's going on and how can I fix this? 

The laptop is only about 6 months old and the battery seems to be in good health.

    Windows will automatically reinstall the drivers the next time you restart/power on your Surface

    Has anyone here been able to verify that this "fix" works? I haven't had an opportunity lately where it's been convenient to shutdown my PC for 10-12 hours, and frankly, I'd like some confirmation that this works before I even bother to try. 

    I can verify that mine was fixed and working normally. Thanks for advice.

    I'm having a similar issue with a Surface Book 2. The battery drain while off is not as drastic, but is something like 2% overnight and will continue to drain while off.  

    I took it in since it was only a month old or so to a Microsoft Store and got an exchange. I had run extensive battery reports and sleep studies. I worked with Microsoft Support via twitter too. Nothing helped. I tried the battery driver removal for the tablet portion but that did not work.

    I got an exchange. The exchange was not brand new. I ran a battery report when I got it to see the tablet portion had 30 something cycles while the base had none. However, it worked fine for a short time. I actually kept a log and never had one issue with the exchange as I got it for the first week + or so. I turned it off and on every night while using another computer. The battery never drained. Then I started with updates and slowly installing a few programs I typically use, which are not complicated. Office, and a few others. Then the drain started. I don't think it's a firmware issue, but a windows update. Who knows really.

    This one is older but shows my case. This is actually worse I think than my brand new Surface Book 2. I think it's overnight drain was 2%.
