2. If you still cannot use it when you are sure that there is electricity, you need to check whether the keyboard and the computer are connected properly.
You can press the NumLock key on the keyboard to see if the light on the keyboard is not bright, if it is not bright, it means that there is a problem with the connection between the keyboard and the computer, under normal circumstances, there is a problem with the keyboard driver, you can move the mouse to \"my computer\
