The problem resolved itself after normal use for a while - I suspect it was after I worked on battery for a while, and charged through PD from a thunderbolt port, and then when I went back to the Dell charger later, it was recognized correctly.  Weird stuff
XPS 9500 - after recent Windows updates which were after Dell updates including latest Bios 1.19 This seems very similar to [URL]#M89098  I have the original 130W charger attached. Bios reports 130W, but Windows shows "Slow Charger" and an exclamation point [IMAGE] My Dell app Reports charging "30%/hr"  I have tried shutdown and restart, and also holding down power button for a long time to shut down without AC power. No dice - still get the warning.  Any suggestions please?  30%/hr seems slow to me.
