Touch Screen Not working Issue

Hello, I have an early Eve V. The touch screen was working a few days ago, now nothing.
the Device Manager shows the HID Touch Screen Driver loaded, but the information says It cannot find the touch screen device.

Since Support does not respond to support questions, I put this out to all of you.

FYI the processer is not supported by Windows 11 (It would be nice if we could get one that does and replace the current one. but I am sure Hong Kong will not support that. Also there is no place I have found in the US where they support the device.) buyer beware

Possible things to try (that you may have already tried), in increasing order of level of hassle (and data/application loss) to determine whether it is a hardware fault or just a software problem:

  1. Completely turn off the PC by holding down the power button for more than 15 seconds, and then turn on.
  2. Go back to a system restore state that predates when the touch screen stopped working
  3. Reset Windows 10 to its default state or do a clean install
  4. If you made a backup of the SSD when you first received the machine, restore that backup to take it back to its factory default state.

Note that Windows 11 does install on the V with registry change to ignore out-of-date CPUs. I have Windows 11 running on my V and it seems to be running fine.

Hi, I went back to the reset windows 10 point. re-installed and still the touch screen does not work. Grrr. I hope the update to windows 11 with the registry override works

Hi. Yes, you can install Windows 11 with a registry fix, but I don’t think that will fix anything - it certainly didn’t fix my fingerprint problem. Do you have any items in “device manager” with an “!” indicating that there is a problem?

There are no issues in the windows device manager. I upgraded the Bios and that restored the touch component of my Touch screen. The downloads available on the evedevices.com/support are not very clear at all, but trial and error seems to have worked. When I did upgrade to windows 11, it would not permit any updates, that is something I was not prepared for, since we know MSFT is a buggy product at best since so many moving parts. I am now back to windows 10 and building on that. When EOL comes for Windows10, I will go from there.

The BIOS upgrade seems to have fixed the touchscreen issues

However, now the screen no longer works. Oh and don’t ask for support. Their team are all in Ukraine. :frowning:
