ThinkPad X1 Carbon 6th Gen: BiOS update adds S3 suspend support for Linux

Finally Lenovo gave in and we don't need the community hack (https://github.com/fiji-flo/x1carbon2018s3) anymore!

Thanks for all the support and contributions to this project.

If you're looking for a great Linux laptop, this is one. Very happy with the 5th gen.

I have the 6th gen X1, but still using Windows, and still its behavior bugs me a little bit --

I almost never really shut down my laptop (does anyone?) -- I simply close and open the lid. Annoyingly, the X1 still wants to persistently be connected to my Airpods via bluetooth. So lid close doesn't actually put it on sleep suspend, it's some other weird middle suspend mode which is not really suspended at all.

How does windows behave with this option ? Would be interesting for those dual-booting. Things should work fine, but any major noticeable differences due to the lack of connected standby mode in windows ?
