ThinkPad USB-C Dock not charging ThinkPad T480s Laptop when connected. How to fix?

It won't charge it when the laptop is plugged into the dock. The battery icon in the bottom right of the screen says "96% available (plugged in, not charging)." Anyone have any ideas?

Let it drain down under 90% and try again. Seeing that message at that level is by design to protect the battery.  If it fails at, say, 70%, but the charger that came with the computer works, then there may be an issue with the doc. But "96% plugged in, not charging" is normal.

Did u try to charge separately? restarted? Perhaps the update is not installed on time. Or do as said above, good luck

It’s never done this before at any power level, also won’t charge when AC adapter is plugged in.

Run the computer down to 80% and see if it happens at that point.

Will do, the battery doesn't seem to really be draining more than ~1% an hour, so it is at least getting some power to it I think. The IT department for the company I work at couldn't really figure it out either - updated bios and drivers, etc. Will respond if I get it working, thanks all.

"Plugged in, not charging" above (I think) 95% is a battery-protection feature. Disconnect power and let it run down below 90%. Then connect the AC adapter (not the dock). It should show charging. If so, THEN reconnect the dock.
