I have been using my Acer 10 tablet for about six months and had upgraded to Win 10 a while ago with no problems. This morning the keyboard stopped working. I checked the contacts to the tablet because it has a detachable keyboard, cleaned them with a soft brush, cleaner and rebooted, no luck. The keyboard when it boots allows me to key in my password and I have a USB mouse attached to the keyboard that works, but none of the keys work once I'm logged into Windows? If the screen times out and I try to enter the Password again, nothing. I can navigate around using the mouse, but have no ability to enter keyboard information. I went to Devices and uninstalled the keyboard drivers, rebooted, nothing. I ran Windows troubleshooting for devices, nothing. The onscreen keyboard has always worked. Since the keyboard does work for login I've concluded its a software problem. I'm stumped and would appreciate any suggestions, all welcome.
