RE: Touch Screen has stopped working on Dell Inspiron 15R-5537
If the touch screen still doesn't work:
Installing (touch screen)drivers through Windows Update - Type Setting onto [Cortana] search box, click Update And Security, and select Check for Updates. Install any available updates and restart your computer if required. After, check if the touch screen driver appears in device manager
If the touch screen still isn't fix, I suggest you update the System Setup( BIOS). Please click on link below to safety install latest BIOS version.
After installing latest BIOS version, run Guide Me option in your Dell Product Support page. The tool will detect drivers updates for your system. Please follow instructions to run Guide Me option in link below:
