First, we need to identify the specific symptoms of the problem. If the keyboard light comes on, but the keys don't respond, then it's probably the keyboard itself. If the keyboard light is on, but the characters entered do not correspond to the keys, then there may be a problem with the keyboard layout or language Settings.

To solve these problems, we can adopt the following solutions:
< br >
1. Check the keyboard connection
< br >
The keyboard may not work properly due to poor or loose connection. Therefore, we can check whether the keyboard is firmly connected and whether the correct interface is inserted. If you're using a wireless keyboard, try reconnecting or replacing the battery.

2. Check the keyboard driver
< br >
There may be a problem with the keyboard driver, causing the keyboard to not work properly. We can try to update or reinstall the keyboard driver. The keyboard device can be found in the Device Manager, right-click and select \"Update Driver\" or \"Uninstall Device\
< br >
3. Check the language and layout Settings
< br >
If the characters entered on the keyboard do not correspond to the keys, it may be because the keyboard layout or language Settings are incorrect. We can find the \"Region and Language\" Settings in the Control panel to ensure that the keyboard layout and language Settings are correct.
< br >
4. Check the keyboard hardware
< br >
If the above methods can not solve the problem, then there may be a failure of the keyboard hardware. Try connecting the keyboard to another computer for testing, or replace the keyboard.
First of all, wireless devices, whether it is a wireless mouse or wireless keyboard, are to be charged (some use batteries, but it is certainly convenient for rechargeable wireless devices), so the owner of the building first ensure that their equipment is powered. Second, the device does not operate normally in the case of sufficient power, or it is your hardware failure (including signal receiver failure, circuit board failure, etc.). It is the software error floor since it is an all-in-one machine (that is, a brand machine), directly call Lenovo after-sales is, do not worry about solving the problem, I hope my answer to help you!
