Unresponsive Keys, but only sometimes?
On my macbook laptop, the left cmd, x and z keys are unresponsive most of the times. This is where it gets weird, sometimes they work at random! How do I diagnosis this problem? I'm totally clueless.
Also, at first I thought there was something physically wrong with my keyboard, perhaps something is stuck that prevents the switch from being recognized but then randomly it starts working. sometimes it doesn't work for hours, other times it does. There isn't a scenario that I can reproduce making it work. I also opened up my macbook and looked at where the keyboard ribbon is connected to the logic board, I don't know what is up.
