Hi FIvedezs, Blake_ASUS, I've had the same issue where the touchpad suddenly stopped working and I can't even see there is a driver for the touchpad installed now. I've had this happen before and couldn't find a fix - I used a mouse for months which was really annoying then a further update fixed the problem. It's simply not practical for most people to be without a laptop as it's sent to a service centre for examination.
The link above to the ATK package doesn't work so I can't try this. I've tried to download the touchpad driver but can't install it as "a program run as part of the setup did not finish as expected"
What can be done and why does this problem occur?
