I have an Asus x541UA laptop. After an upgrade of windows 10 the touchpad stopped working. I informed Asus of this and their reply was to reset to factory settings, this I did which took me back to windows 8.1.
After again installing Win 10 the touchpad stopped working. When posting online I found that lots of people had the same issue which could not be resolved. I again informed Asus and their reply this time as the warranty had expired was to send it to them for repair at an Exorbitant price, this I declined. The drivers on their site do not work and it seems they do not seem want to produce a driver that will resolve this issue.
I am now in the process of finding a laptop from a good manufacturer and this on is going in the bin. My advice STAY AWAY FROM ASUS.
A shame sitejabber don't let you do a minue rating.
