I hope all are doing well. Some friends reommended this forum and said its the best to solve my problem ! For the last week or so, my Mabook Pro laptop keyboard letters C and X stopped working, in other words when i press them anywhere they dont work and the edit menu flashes. Also i like to tell you that when i am pressing Shift and X or Shift and C , they do work , but in Capital letters. I really appreciate your help please. Thanks in advance.

P.S / Here is my Mabook Pro info:

<Memory: 4 GB 1333 MHz DDR3
Graphics: Intel HD Graphics 3000 384 MB

When you press the command key with "c" or "x", you will either cut or copy highlighted text. That is why your edit menu is coming up when you press c or x, your command key is probably stuck. Try to see if it is, is it lower then the other keys, can you put your fingernail under it and pop it up a small bit?

Right, because the command button is probably stuck so when you press c or x, its like you are hitting both keys.

Edit functions probably don't work in the log in window so it doesn't matter that the command button is stuck when you log in.

Yes, I'm sure it could be software but I don't know how to check for that or how to solve. Hopefully someone else on the forum can help.

(Can you connect another keyboard to it and try that? If it still happens, its software; if not, its hardware)

That's weird. I see what you mean. Sorry, I'm out of ideas.
 
The guys who commented and asked me to stop highliting my question ! Firtsly , its a forum and the question was not addressed to you , then , if you like ignore it and dont answer ! Secondly , i hoped if you could say somthing useful for the problem instead of distributing advices .
 
I spilled some liquid on my keyboard once. The computer didn't get fried, but one letter stopped working. I had to replace the keyboard.

I have no idea ! I dont have another keyboard .... Do you have other recommendations please ..

Can't think of anything right now. If an external keyboard exhibits the same behavior then you'd be able to eliminate a mechanical issue with the laptop keyboard.

The cheapest USB keyboard in the world would probably be sufficient to test.

Thanks for your kindness and respond, just I want to highlight that the problem is a software one because (C and X) works in safemode, and also when i am logging in the computer, i am very positive that they are associated with some other apps that stops them from working, but dont know which app or how to make them work again....
 
If it is an app and you don't know which one uninstall and reinstall them one by one until you find the culprit. Start by disabling or installing all those enabled at login.

Also, plug in an external keyboard and test to see if it works fine when the MB's doesn't. I believe you will also need to plug in an external monitor and close the MB to avoid it seeing both keyboard. You need to positively eliminate the keyboard, not just think it is not the problem.

I came in here to help but when I see a person asking help every 5 mins., I decided not to. Highlighting your question is fine but not every 5 mins. You need to learn what patience is. We don't get paid here nor we work here 24/7. Only babies require such high attention. Are you a baby? I bet not because you own a MacBook so why do you need such high attention?

By the way, if you actually read the forum rules then you would know that bumping a thread with useless post is against the rules. I have copied it for you to read.

"7.Bumps. Posts that bring a thread to the top of the New Posts list but add no content to the thread (bumps) are not permitted. This applies not only to posts that say "bump" but to those with the intent to bump, e.g. posts saying "anyone?" or the equivalent. See why and how to avoid bumping."

Off the wall idea... Check the Accessibility System Preference, specifically the Keyboard settings and see if "Sticky Keys" is enabled.

1. Plug in an external keyboard, then:
2. Disable internal via the instructions here:
https://forums.macrumors.com/posts/9536110/ or here:

http://t3chnot3s.blogspot.com/2013/12/disabling-built-in-keyboard-and.html

3. Text to see if MB works normally. If yes, internal keyboard is the problem. If no, do what I said about disabling software. Alternatively, you can do a complete wipe of your HD and reinstall programs one at a time if you can't find the problem by disabling/removing programs.

If you refuse to try what is suggested in this forum then you are just wasting everyones time posting here and will wind up ignored.
