Hi there, I saw similar threads, but, its little confusing... My problem is following: I have Acer Aspire e3-111 26UJ. I installed Windows 8.1, firstly in legacy mode, and all components worked. Touchpad worked without drivers, started from low level hardware when I pressed FN+F7. I changed my mind, and deleted everything, installed Windows 8.1, from UEFI mode. Even from installation starts, touchpad wont work. Now, its not working too. With or without drivers. If I press 2 3 times fn f7, keyboard not responding anymore, and windows restarts with message that my computer went to trouble... Does anyone solved this horor?
