I have got myself this laptop due to it's size and upgrade options.It worked great at first, but then the touchpad started to freeze!!!!!! No matter what OS I have used - Win 7, Win 8, Win 10 - touchpad freezes and only Fn+F7 will restore its functionality for few seconds or for a few minutes. I have sent laptop back to Acer and all they did - reinstall windows OS. And of course touchpad worked on a fresh installation. I have done that myself numerous times!!!! Afer you reinstall
OS it works for few days and then issues appear again. I wish I can return this laptop and get my money back 
Currently I have latest BIOS, latest drivers and Windows 10.
I have seen numerous mentions from other people about same issue, and noone have mentioned the permanent fix. So is there a fix for this issue? Or we are stuck with a semi-functional laptop?
