Hello there, I'm facing a problem with my laptop touch screen I have been trying to fix it but I couldn't.. when searched on google for answers it showed me that I have to go to device manager in control panel then choose human interface devices. but when I click on touch screen It shows me that the device is working, but in fact it's not working at all! I hope you can help me solve this problem
