The 2-in-1 aspect meant Dell had to make sacrifices in cooling the CPU (i.e. I ended up returning the machine anyway though.

This rectified the intermittent touchscreen functionality issue. In the end, I had a site visit and the technician agreed with me that because the touchscreen didn't come back to life when in the BIOS, it was a hardware problem, and so the screen assembly was replaced.

The System app shows Pen and Touch: 'Pen and Touch support with 10 Touch Points', but touching the screen with fingers elicits no response whatsoever.Īnyone got any ideas - or is this a known hardware issue which needs a hardware support call. I'm completely up to date on BIOS (1.1) and all drivers on Windows 10 Enterprise. Using the component test on the Dell Support site just doesn't work as it's interactive and I have to fail out all the tests. I've power cycled a number of times and still nothing.ĭevice manager shows the device with no issues, pre-boot testing shoes no problems (although doesn't appear to explicitly test the touch screen), and most bizarrely (although might be completely explainable if it uses different tech to the multi-touch), my Dell Active Pen (PN556W) still works fine. Today, I've booted up from power off and the touchscreen doesn't work at all. Recently I started noticing that the touch function on the QHD+ screen didn't always come back when the computer resumed from sleep and would require a power cycle (power down - power on) to come back - simply restarting the system did not help. I've had my 2-in-1 for about a month now.
