Hi, most of the keys on my Acer aspire 5750 have stopped working. I have tried to connect a USB and a wireless keyboard and these don’t appear to work at all. The USB ports appear to be working as my attached mouse is all good as is the touchpad. I have tried rebooting and resetting the keyboard settings etc. As far as I can tell my drivers are up to date as well.\nAny help would be appreciated, I imagine its more complicated than just replacing the keyboard?\nThank you.
