no custom power profiles.
That's odd. I have 3: Balanced (recommended) Power Saver (which I switched to once when I noticed that I had been in the "Plugged in, not charging" state) and High Performance. Oh. Maybe the CU has changed that last one? No. It's still there, slightly
hidden under Show additional plans. So, looks like I used the wrong word to describe what you would need to look for: it's actually "Power plan."
One thing the CU changed is what Win-x O does but it is still possible to get to the Control Panel, Power Options to see these. Also, at the bottom we are reminded that the Mobility Center (Win-x b) provides an easy way to switch plans. That is also
where the problem symptom seems most evident. I hadn't noticed before but right-click on the Battery icon in the Taskbar also provides quick navigation to these elements, bypassing the new modern dialog.
FWIW it looks like in my case 99% available (plugged in, not charging) means that it can use the power but not deplete the battery. I wonder why your battery gets used then? So, one difference between us would be that you will have the ability to use Connected
Standby. Then if that is enabled, perhaps disabling it would cause a useful change.
Good luck

Robert, I'd like to know how you got any other power plan to appear, other than Balanced. I've had a Surface Pro 3, Pro 4, and Pro (2017), and since Win10 none of them have ever had any other plans available besides Balanced. There is no "show
additional plans", there is only Balanced and nothing more.
Back to the "plugged in, not charging" issue, I have occasionally gotten it before on the Pro 4, but usually only when using certain apps or programs. However, even then it was still only sporadic, not 100% reproducible. Now with the latest 2017 generation,
I have been getting the issue at least once/day, but does not seem at all tied to running any specific programs. At first I thought it was a bad power supply, so I replaced it, but the issue came back the next day. It appeared again just this morning, and
this time I put the Surface into hibernate, unplugged it from the docking station, unplugged the power from the dock and let it sit for a few moments. Then I plugged the power back into the dock, gave it a moment to "wake up", then reconnected the Surface
and woke that up too. After everything was back up & running, now the battery is charging normally.
A very mysterious problem, that Microsoft should probably take a closer look at. I love the Surface devices, but as others have mentioned, we rely on these machines to get work done so batteries that don't charge are more than a minor inconvenience.
