I updated to the BIOS from November 2018 for my XPS 13.  I noticed that I was getting the dreaded plugged in not charging.  If I rebooted it looked like it was working but I'm not 100% sure on that.  I have multiple power adapters plugged in around the house.  It didn't matter which one I used it said it was not charging.

I re-installed the previous BIOS 2.2 from October and everything seems back to normal.

I just unplugged for a bit to run the battery down more and it is now charging fine.

Anyone else seeing this?  Help DELL this BIOS upgrade has issues.
