XPS 15 9500 (2020) - AC adapter not recognised post My Dell Support update
Hi All
Very concerning issue.
Just did a My Dell > Support Driver Update and a Windows Update to Windows 10 Pro 19042.685
The Dell Support did two activities
- Realtek Audio Driver Update - A07 (598.21MB)
- SupportAssist OS Recovery (180MB)
I immediately noticed that the Audio Stopped working properly and instead of playing the audio, I would hear a hissing noise - volume rocking up / down using the Windows slider just made the audio hissing louder or softer
I then used Windows Device Manager to rollback the driver and immediately after a restart the audio was back !
Then after a few hours of use, Windows advises that it was low on battery. Connected the cable (light on cable) from supplied charger but it wouldn’t charge.
Instead windows advises : “Cable plugged in but not charging”
The front LED indicator does not turn on either.
Tried to update the AC adapter driver in Device Manager - but no new drivers and no driver to rollback to.
I restart the PC, plug in the cable - same message
PC battery just drained to 3% when I did a shutdown.
Laptop was fine until I did the DELL update today and things started failing one after the other.
My Dell XPS 15 9500 (2020) is just a very expensive metal brick.

I had the same problem, getting worse by the day, and finally traced it to a bad USB port expander (dock), after more functions on the dock started to fail. I replaced the device originally purchased with my XPS in 2021 with a newer and heftier model from Dell Dell (Thunderbolt Dock – WD22TB4 ), and everything seems to be stable. I don't think my adapter was the problem, but I was able to leave it off anyway, since the XPS recognizes the new dock as an adequate power supply.

Hello,
I have the problem again. AC adapter not being recognized and neither is the thunderbolt dock. I will have to properly shutdown the system then, unpluss the cable, insert it, wait until the led at the front lights up and only then can strart the system.
Plus, laptop again randomly crashes / reboots. Now every 5-10 minutes.
This has happened in the past, and I got my laptop / mainboard replaced.
Please help. Thank you
