Dell laptop touchscreen intermittently stops working. I'm able to turn it back on by going to device manager, human input devices, HC compliant touchscreen, and disabling the driver, then enabling it again. But this is happening multiple times in a day and the screen often out on me when I'm in the middle of a game, which is extremely annoying because by time I realize it's stopped again and grab the mouse, the game is messed up. There is no power management tab for the touch screen (and the laptop is plugged in anyway) so that doesn't seem to be the issue. And it works again when I do the disable/enable sequence, so it doesn't seem to be due to being dirty or any actual damage to it, since it works again just fine. Why does it keep stopping and how do I get it to just stay on? Edited to add, I checked drivers and it says it's up to date.
