Net rumor is early Dec 2015 Windows 10 update caused some ACER laptop keyboard failures. Mine failed after system restart following update. Internal keyboard check shows keyboard good. F11, number lock, is not the problem. One column does function, 3edc. ACER offers no keyboard drivers for any OS for this computer. When I look at driver details from my control panel, it says "Driver Provider: Microsoft, Driver Date 6/21/2006, Driver Version: 10.0.10586.0, Digital Signer: Microsoft Windows." The Driver File Details shows "Provider: ELAN Microelectronics Corp, File version: 11.159.15.5. However, I did contact ELAN, and they say they just do the touchpad and not the keyboard. I have done Windows + X and redownloaded keyboard drivers. I’ve also uninstalled and reinstalled keyboard drivers. Anyone know where to get ACER’s specific driver?
