Hi, I've got a m3800 running windows 8.1. A few weeks ago the touch screen stopped working. If I remember well it stopped working after a windows update or even dell updates, but not sure about this. Drivers are up to date and firmware A05 is running. "View pen and touch info" says : "No pen or touch input is available for this display". There are no tablet PC settings in control panel. A colleague of mine has the same laptop in device manager he has listed 2 HID compliant touch devices, my device manager shows none of both.
I googled for a solution, but so far without luck. I'm wondering if a windows update disabled tablet features ?
Has anybody experienced something similar ? Any help would be appreciated !
