Please read as this may help you somehow.
My touchscreen stopped working all of the sudden. I was writing an email and it stopped completely registering any touches. The open stopped too. Everything else was fine.
I restart did not help.
The device manager had everything working with no exceptions. Searched the internet and could not find a Windows setting to turn off and on the touchscreen.
In the device manager I stopped the touchscreen device and then started it again. Didn’t work.
In the foruns I found many possible workarounds that involved reinstalling drivers or even a fresh windows install.
Before doing that I decided to go into the BIOS.
I found that USB-C and USB HUB options were turned off. Turned them on and restarted windows.
Everything worked again. Touchscreen and pen.
I have been dealing with PCs for decades and never seen something like this. I imagine that it was triggered by an hardware fault and may happen again.
Anyone experienced something like this?
