ASDF keys not working - 2012 Macbook pro 15 Retina
My ASDF keys suddenly stopped working.
Here is what I think is a possible solution, having read every other possible solution - dirty keys, accesibility settings, PRAM etc - nothing worked for me.
Specifically my fault is the same - the ASDF keys only, but I think others may be affected as well.
I found that the keys would occasionally work if pressed hard. Sometimes. then the problem went away for a few weeks, and then came back.
I think it's old age! My 2012 pro is now over 6 years old. It can't really be software if they work when pressed hard sometimes, and it can't be dirt if all 4 keys go together.
Don't laugh, but this is what I did. I placed the palm of my hand over the ASDF keys and pressed firmly, slowly and gently, hard enough to flex that area of the keyboard. It worked!
When I did this, I noticed that at that time my MBP was quite warm. I had been using it a lot. I am not a techie, but I do know that the keyboard has some sort of matrix circuit that senses what keys are being pressed. My theory is that with constant heat expansion and contraction over many years, this mechanism of contacts gets old and eventually under certain circumstances, a section of it goes intermittent. Applying some pressure to the area seems to have remade the connections, because these 4 keys came back to life immediately. And it is still working fine.
I suspect that a new keyboard will be needed eventually - nothing lasts forever. But this "fix" worked for me.
