I have an Aspire A315-24PT. When I first bought it my touchscreen worked fine. Unfortunately, there was an accident and the screen got broken. I had it repaired, new screen put in, no problem. However, now the touchscreen doesn't work at all and the repair place I took it to couldn't figure out why. They said it was also odd that my HID Touchscreen driver was missing, and they were unable to recover it. I did not see it listed anywhere among the drivers available on the site.
Where can I go/what do I have to do to replace this driver and get my touchscreen working again?
