Hi, my B-button on my keyboard only works sometimes. Either it clicks, doesn’t click or clicks twice. I have done some of my own research and concluded that the button always works when clicked anywhere from the bottom left-top left-top right region and the issue only occurs in the center and bottom right parts.
First of all, you should check to see if your computer is eligible to receive a new keyboard via Apple’s keyboard replacement program. I do not advise you to service your keyboard yourself because you could damage the keyboard even more then it is now.
