(please bear with me, I am not an English native speaker.)
This is not about the "plugged, not loading" issue I found around here multiple times.
My Thinkpad will charge via charger only when it is switched OFF. It loads perfectly when plugged via docking station.
Batteries are getting empty, power save mode and all that. Pluging two different power units show same result.
Additional weirdness: ThinkPad does not start when plugged to the charger. Hitting/pressing the power button at the right of the keyboard has no effect at all. Once unplugged from charger, it boots just as usual.
While typing this with 9% remaining capacity, computer shut down. I plugged it to the charger and closed the lid --> orange light. Waited a couple of minutes. Opened lid. ThinkPad wakes up, and I continue writing.
Again: charger is plugged, LED light is off again, info tray says not loading/in use.
I am running M$ Win10 Enterprise.

If you recently upgraded to the 1803 version of Windows 10 that may be what caused it.
When you click microsoft battery icon on the task bar does it show both batteries?
If you look in Device Manager are both batteries listed?
The windows 10 - 1803 update screwed up a lot of Thinkpads with two batteries.
So, if the answer to the above question(s) is NO try this:
The same thing happened to me on my T480
Here is how I fixed it:
I may have some extra unnecessary steps in here, but I wanted to be sure I didn't screw it up:

Thank you very much for your reply and detailed description. The answer to both of your questions is "yes".
(I found the hint concidering remove batteries via device manager somewhere else and gave it a try. Both devices re-appeared after reboot, behaviour unchanged.)
No I am sitting at my desk using the Lenovo ThinkPad Ultra Dock - 90W EU - FRU: 40A20090EU. Task icon shows battery symbol plus power plug. Message says for both batteries: 100% and charged.
I would like to avoid removing battery and all that. Any ohter ideas?

I guess I'm confused.... but I'm up late ;-)
What is the issue at this point?
To do what I had suggested you ONLY have to remove the EXTERNAL battery (the one that slides in and out),
NOT the internal battery. So really not too much of a bother.

Two issues (at this very moment):
Or do I miss something?

Sorry I had replied on mutltiple threads and got them confused.
Correct the "S" models do not have an externally removable battery...
You could still try turning off the batteries in BIOS and seeing if things changed.
As far as I know there is no risk of messing things up worse, following the procedure except for the part about removing the battery.
Although in your case it maybe you are correct and ultimately either have to re-install or physically disconnect the batteries :-/
I don't have any other machines on which to test.

No prob, thank you.
Hm... BIOS and physical disconnection ? I will talk to our IT staff here. Being "just an ordinary user", this is above my level.
Will get back later.

To physically disconect you would have to disassemble the machine.
But I think this step makes that unnecessary:

I disabled the battery in BIOS. BIOS shows only one battery, while task symbol and Device Manager show two.
After speaking to our IT, we found out that my business ThinkPad is still under support. I contacted Lenovo Support yesterday. Installed Lenovo Vantage. Ran some BIOS and firmware updates. Did not help.
Calling Lenovo support today, they told me to ship it in for repair. This will take approx. one week. I will be out of office for a couple of days at some time in the next two months, so I will probably arrange this.
BTW, setting the BIOS option "Start computer when AC plugged" or similar helps: ThinkPad boots when connected to charger. Windows lock screen shows charger symbol . Once unplugged and reconnected to the charger, I see the battery symbol only. Workaround.
When I got my repaired machine back, I promise to finally (?) post here. Thank you all for reading and especially JimBobMC.
