Can you help me, how to install the touch screen doesn’t work.I can’t press any key in virtual keyboard, or any icon at all.Ican only use an external keyboard.
First determine if the problem is hardware or software.
If the tablet has received a blow or pressure on the screen, the touch may be broken and only a replacement can solve the problem.
If it’s a driver problem, reinstalling the touch drivers will bring it back to life.
If the tablet has not received a blow or pressure you can go to the device manager and go to the touch controller in case it has a yellow triangle indicating that it is not working correctly.
