I've had the problem ever since upgrading to Windows 10. The touchscreen only works in bios (so it's a software issue) but not in windows. The windows button bellow the screen works just fine.
I've tried to instal the newes chipset and graphics drivers and have the newest bios. I've also tried drivers designed for windows 8.1, but they haven't worked either.
The HID-compliant touchscreen is missing from device manager, so can't update the drivers from there either.
Resetting windows hasn't worked either.
Is there a solution to this, or is the biggest selling point of this laptop now useless?
