Q: Left shift, left control, and left option keyboard not working
I do not know what happened to my macbook, suddenly when I want to use it, shift, option and control on the left is not functioning.
I've tried a variety of ways ranging from
- Reset nvram
- Reset smc
- Change the input source on the keyboard preferences
- Delete a file type of keyboard on "Library / Preferences /" but still did not work.
the strange part is when I do a reset smc for the first time to have this happen and still does not work, I still use my laptop and suddenly all the buttons work, but it did not last long. the problem reappears, and on the same shift, control, and option parts left.
then I do a reset smc back in the hope of going back to work as before, but until now still is not functioning
things I have not done is to re-install my laptop.
does anyone have the same experience? I seek guidance
if I had to replace the keyboard or is there another way?
thank you
MacBook Pro, OS X El Capitan (10.11.6)
