XPS 15 9510, U4919DW, charging light goes on/off for few seconds when connected
XPS 15 9510
Can you please explain why the charging light on my XPS 15 9510 sometimes turns on and off for a few seconds while it's plugged into my Dell U4919DW monitor using the USB-C cable that came with the monitor?
I also tried a different USB-C cable, but the issue persists. Additionally, I keep getting a popup message saying 'weak charging,' even though I am 100% using the correct port on the monitor, and the cable is brand new and in perfect condition.
Thanks a lot!

Dell Support must verify the ownership and warranty status. Click the blue "Get Help Now" on the right to start a private live chat session. Share the private U4919DW Service Tag and XPS 15 9510 Service Tag with them.
The U4919DW #5 USB-C port only delivers up to 90 W power delivery back to a Laptop.

Be sure that the USB-C cable is connected to one of the XPS 15 9510 leftside TB4 ports.
