The cause of the wireless keyboard malfunction is basically either the battery is running out of power, or the wireless signal is disturbed.
1, first, if there is no battery, buy the new battery replacement can, I believe we all understand. This is due to the fact that the keyboard occasionally fails the most.
2, of course, there are some instruments to interfere with the wireless keyboard signal, the general wireless keyboard is 2.4Hz wireless band, this if the wireless keyboard with some such as Bluetooth, cordless phone will interfere with the wireless keyboard signal, so move these devices to other places is good.
3, the above situation is not the case, then the user you first check if you are in the wireless keyboard is just entered the standby mode when this failure occurs. Then the standby mode is the occasional failure of the phenomenon will occur.
