50IJ WEIRD keyboard problem

This started a couple days ago seemingly out of nowhere.

The "a" and minus keys don't work. The other day, minuses kept appearing in random places in words, then that stopped and "a"s started popping up after certain characters: d, f, j, k, l, and ;. Minuses pop up if I hit the "fn" key without hitting anything else. They will go on continuously until I hit another key.

Nothing changed in safe mode or when I reinstalled the keyboard driver. But I restored the system to before the problem and the "a" stopped popping up after f and j. also, if I hold down the menu key, I can type all the letters normally, but the minus things aren't fixed and I get additional problems: The semicolon button doesn't work, and although both shift buttons and the forward slash all work, I can only make a question mark using the left shift button.

What is this?

 

You can try removing and reconnecting your keyboard, but you need to replace it.

 

any idea how that happened? It was working totally normal, and then all that happened at once. and I've only had it for a few months.

 

It's a keyboard, they fail sometimes. There's a chance the connector is loose, but more than likely you just need to replace it.

 

If it was disconnected, it would probably not say "Device is working properly," right? How can I disconnect/reconnect it?

 

There are some tabs you need to release, and maybe some screws on the bottom labeled K. You remove those screws (if they exist) and then pop the tabs, then the keyboard will lift up. There's a ribbon connector for the keyboard that you gently release by pushing each side of the connector out.

Here's a generic walkthrough I posted in another thread.
