What should I do if the left button of my laptop fails?

When this problem occurs, first you need to recall what you did before, and then the left key now becomes the reverse key of the right key. Secondly, if it still cannot be solved and if necessary, you can reinstall it. system to perform exclusion testing.

What I want to say here is that the left and right buttons are swapped more. I prefer the swapping of the left and right mouse buttons, so when you talk about the left and right buttons here, you first need to clarify whether they are swapping of the left and right mouse buttons. , this can be restored through the settings in the mouse control panel. Of course, if it is a keyboard, then this is more likely to cause damage to the keyboard keys. In this case, I suggest you first test it by replacing the normal USB keyboard, and then decide how to solve it after ruling it out, because if it is a laptop keyboard, then Maintenance needs to be taken into consideration, and whether it is worth repairing or not, it is up to you to measure its value and whether it is necessary to replace the laptop keyboard.
