My ‘b’ key won’t work on my keyboard

Technician's Assistant: What kind of Apple device do you have? What Operating System (OS) are you running?

I’m not sure... I always try and stay updated: additionally, the letter b is part of my password ***** I am sending this from my iPhone

Technician's Assistant: Anything else you want the Mac Expert to know before I connect you?

.. a few other letters also do the same..... but not as often

Ask Your Own Mac Question

Are you using a wired or wireless keyboard?

Can you see a model number anywhere on the keyboard?

MacBook Air

Ok, so it is a built-in keyboard.

Can you see any debris under the B button on your MacBookAir?

Can you carefully lift the button up and clean under it using a vacuum cleaner?

If you attach an external keyboard does the B button work ok?

I have already used compressed air ....
I do not have a remote keyboard
Customer reply replied 4 months ago
I took the tip of my knife and raised up the key just a bit; there are 3 lights... but one is not as bright as another key I looked at...

Ok, then the MacBook will require a repair to replace the keyboard if cleaning did not work.

What Customers are Saying:

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
