Touchscreen does not work

[Jerome Vet]

Hi

i have the Chuwi hi12 dualboot tablet.

the tablet is for my parents, yesterday installed all the updates , app etc thay need . all worked just fine.

but after restart, the touchscreen does not work anymore,  ( its not hardware, couse it does work in android )

tried every thing i could find on the internet , replacing the touchscreen ini, reinstalling drivers etc. nothing worked

 

there must be a other conflict going on, couse for a brief second the screen worked after reinstalling, ( just one time ! )

wat can be the problem , i have 20 years of pc experience so all the logical options have been tried !

also looked at the windows defender to see  if it removes anything , but could not see any file had been removed by defender.

non of the drivers for the screen make any difference , also tried to look for the original Surface pro 3 screen drivers since the screen is the same als this did not work.

i am thinking of reinstalling the complete tablet without dual boot to fix the problem. if it fixed it at all !

any solutions to try ?

in a thread below there is a file touchscreen.gt that works wonders with the touch.If that doesnt help you consider formating windows

no I have tried that to , also change it to read-only and does not work.  I also tried the touchpad fix , that did not do anything to.

the bios upgrade went wel ( may 18th version ) but dit not change anything.

it looks like something keeps overwriting something , I changed the touch accuracy in pen and touch, and right after pressing apply.

and it worked for a second and then went to not working at all!

just need to keep on fiddling then 😀

I am a bit skeptical about reinstalling , its a dualboot and I want it to be just windows 10

i have reinstalled the dualboot OS,  formatted a 32gb usb to ntfs, made it a bootable usb with rufus.

after that i copied the dualboot file onto the usb, and rebooted the table with the usb in the 3.0 port ( faster 😀 )

and it installed without problems, just booted the usb and it started to install,

did the basic windows setup en the screen works again.  made a extra backup after the basis software install so i have a clean install backup.

now just see if windows updates makes the screen fail again !

Hi, hoping you can help my mom spent €300 on this tablet last week. I was in the bios and think I changed something by accident and now touch screen and home button won’t work. Please can you help I’ll be so grateful thanks

@Darragh: If you changed something in the bios it is an easy fix. Just set bios settings back to default in the last menu, before quitting and all must be well again.

I think the problem is that the driver “KMDF HID Minidriver for Touch 12C Device” has been deleted
