I have a ‘Dell Latitude 7275’ and deactivated the touchscreen 1-2 years ago, but I can’t remember how. I am currently trying to reactivate the touchscreen, but all the options I have tried so far have failed. Are there any other options that I haven’t tried yet? or any ideas why it still doesn’t work?
Is there maby a hidden BIOS menu for hardware components or somthing else I missed ?
What I have tried so far:
-
Checked the hardware and connection from the display to the main board
-
Installed Win11
-
Delete the complete memory and reinstalled Win10
-
Installed all drivers available for the device from dell
-
Added TouchGate to the registry ‘HKEY_CURRENT_USERSoftwareMicrosoftWispTouch’ and set it to 1
-
Tried to update the touchscreen driver in the Device Manager under Humane Interface Devices (did not help)
-
Checked in the BIOS to see if there is an option to disable the touchscreen (there are no settings for the touchscreen or other hardware components and the BIOS is up to date)
