Standby is broken since the push from S3 to s2idle, this was a wintel move. On windows my laptop would die after a day until I finally forced standard S3 behaviour. After the switch back to S3 it lasts a week again and the resume time difference is negligible.

My Lenovo dock ethernet has gone from not working on Linux and being fine on windows to the other way around.

I do not share your enthusiasm. And since dumped windows entirely after the latest update. Last time I installed windows it took me longer to disable all adds and spyware than to actually install it, another reason for switching.
