1, first of all, if there is no battery, buy a new battery can be replaced, I believe we all understand. This is the reason why the wireless keyboard does not respond to the most cases.
2, of course, there are some instruments that interfere with the signal of the wireless keyboard, the general wireless keyboard is 2.4Hz wireless frequency band, which if there are some wireless keyboard next to the Bluetooth, cordless phone will interfere with the signal of the wireless keyboard, so move these devices to other places.
3, if the above situation is not, then the user first check whether the wireless keyboard has just entered the standby mode when this failure will occur. Then standby mode is the occasional wireless keyboard does not respond to the phenomenon.
1, the wireless keyboard can not be used, the first thing you can think of is that the battery is out of power, at this time, you only need to put the battery in the keyboard, and try a new battery.
2, if the battery can not be solved, restart the computer, and then plug the USB receiver on the computer to plug it back into another USB port on it.
3, check whether the switch at the bottom of the wireless keyboard is open, if it is not open, it is to open it and see whether the keyboard has a response.
4, under normal circumstances, the wireless keyboard is not used for a few minutes, the keyboard will enter the standby state (power saving mode), this time to press may also have a \"failure\" situation.
1. If the battery problem is excluded, we will test the wireless keyboard on other devices. If there is still no response, proceed to the next step.
2, pull out the usb interface and try another interface to eliminate the problem of the usb port.
3, if the above can not be solved, right click this computer, click management.
4. Click Device Manager.
5. Find the keyboard in the list on the right, right-click the keyboard driver, and click Enable device. If the driver has a yellow exclamation mark, right-click the driver to update the driver or reinstall the driver after uninstallation.
