I'm not even using Windows, but MS has ruined it for us all. S0 works reasonably well on my ThinkPad X13 G2 with Ubuntu, meaning it goes to "sleep" and wakes up without problems and last a couple days to a week. But is this what I want? I don't need some always-connected bs, thank you! I can wait 5 seconds for my laptop to wakeup and then check for new mail. Seriously, MS, do something.

Edit: Or is Intel to blame here? I don't know.

Edit2: Or maybe Lenovo or all 3? Didn't this work in the past pretty flawlessly?
