Found the culprit. It's the display adapter. The problem reappeared after reformatting my computer and after the adapter was updated through Windows Update. That changed the Display adapter in the Device Manager from "Microsoft Basic Display Adapter" to an "Intel(R) Iris(R) Graphics 540" which again caused the issue. I again reformatted and installed the Intel display adapter from Dell's website via USB stick. Again, the laptop's touchscreen stopped working. But because I installed the Intel driver from the USB stick and not Windows Update, I was able to roll back the driver to "Microsoft Basic Display Adapter" and now my laptop's touchscreen is working again without any issues. This took me about 20 hours to figure out and get everything back to normal. As if that wasn't annoying enough, the comment to "contact the Dell out of warranty department...for replacement of the touchscreeen" has proven to be bad advice.
Alright, I followed the instructions for Method 1. During the boot the screen blinked from red, to green, to blue, to black over and over. The screen is clean and there were no abnormalities.
The touchscreen and external monitor are set to Duplicate mode in Windows 10. Oddly enough the touchscreen can still be used as an input device even though there's no display on it.
Hopefully you got my Service Tag Number over private message. What else should I try? Thank you.
Can you tell me more about how you reached that conclusion? Your limited response doesn’t give me much confidence that this would actually fix the problem.

tg183,
Which specific xps 13 do you have? Dell has many xps 13 laptops. Run the diags on the touchscreen by following the information below.
