Use keyboard test tools: There are keyboard test tools that you can find online that you can use to check if every key on your keyboard is working properly.
If none of the above methods solve the problem, then there may be a malfunction with the keyboard itself. In this case, it is advisable to contact the computer manufacturer or a professional repairer for further inspection and repair.
Second, check the software settings.
If there is no problem with the keyboard hardware, then it is possible that the F9 key is malfunctioning due to the software settings. Here are some possible solutions:
