My keyboard has stopped working. When I switch my pc on all 3 of the number, caps and scroll lock lights on the keyboard flash on and go off straight away, they then flash on and off once again a few seconds later as the computer is booting up but they then go off and stay off. It does have a moon button, a sunshine button and a power icon(?) button but if I've inadvertently pressed one of them I can't seem to get it switched back on.
It doesn't appear to be showing in my device manager at all - there isn't a keyboard tab?
My computer does have the option of being a touch screen but I've never used it as a touch screen. Any ideas what could be wrong with the keyboard?
