I just bought ASPIRE E5-511-C0PC with win 8.1. I upgraded to Win10 as this was offered as soon as I finished booting up. Touchpad still worked fine. Then i upgraded drivers from the Acer Care Center. That seems to be when my touchpad fails to respond at all. Without plugging in a USB mouse, I don't even get a cursor. This was Feb 23, 2016
