Wireless keyboard is not responding-main reason:

1. It may be because the wireless keyboard has been used for too long, and the battery installed on the keyboard is exhausted, so the battery needs to be replaced.

2, wireless signal interference wireless keyboard is 2.4Ghz wireless band. There is a Bluetooth wifi digital cordless phone in this frequency band, which may interfere with him. If so, try different angles and see if there is any improvement.

3. If the wireless keyboard is not used for several minutes, it will enter standby mode (power saving mode). In this case, the first press may be "out of order".

You can test it on other computers to see if it works. If other computers can, you can enter the BIOS and use LoadFail-SafeDefault or LoadOptimizedDefault to restore the default settings. If it doesn't work on other computers, look at the model of wireless keyboard and mouse and check the instructions.

What should I do if the wireless keyboard doesn't respond?-General solution

1. Check whether the battery is short of power, which will affect a series of problems such as voltage and signal.

The battery is ok, but it still doesn't work. Then restart the computer, unplug the USB receiver during the restart process, and insert another USB port after the computer enters the system.

3. In addition, it is recommended not to plug in USB HUB for USB reception. Because the voltage on the hub is not enough, problems often occur, so the native USB interface of the motherboard must be plugged in.

Of course, some instruments will interfere with the signal of wireless keyboard. Wireless keyboards are generally in the wireless frequency band of 2.4Hz. If there are some Bluetooth and cordless phones next to the wireless keyboard, it will interfere with the signal of the wireless keyboard, so just move these devices to other places.

What if the wireless keyboard doesn't respond-a special solution

Fault phenomenon:

A machine has Windows 7 installed. Enter the desktop, the screen is black, and the monitor is in the host sleep state (the indicator light of the monitor flashes). This computer is equipped with a wireless keyboard and mouse. You can press "DEL" to enter the Bios, but when you press F8 to bring up the startup option, the keyboard will fail.

Troubleshooting:

After entering the Bios, I found that usb keyboard support and usb mouse support are disaled. After changing them to Enabled, re-enter them, press F8 to bring up the startup options, and the keyboard can be used. After selecting "Boot with Last Correct Configuration", the system can enter normally.
