Hi

Some keys of my macbook stops working randomly. As i noticed this only happens to ~, 1, q, a, z keys. But still i can use these keys if i press them with Fn key.

I do not know what triggers this issue. But it usually goes away when i restart it. This started during the first 2 months after purchase, then i didn't encounter it for last 6,7 months. Now it started again.

Appreciate any help on this.

Thanks

Hmmm....

failing Keys associated on the diagonal like that, typically indicate a hardware issue, however the Fn key throws this analysis off a bit

To trouble shoot further you can:
