Description : It happened to me a while ago, at first I panicked a little, but there was no light on the keyboard. I tried to see if the connection failed, then I tried to connect another keyboard and only finally I thought of trying to restart. That helped, everything is OK, but I'd like to know the cause. :)
Last Answer : To "it alone"? : o What was she doing? - because this can happen because: - the key (cable, controller) has gone - the connector (contact, controller) has gone - something has crossed the driver in memory The third is most likely - given that a restart helped (reloading the drivers) .
