Dell Inspiron 3520, a group of keys are not working
I have a group of keys on my Dell Inspiron 3520 that do not work. They seem to be the 1, Q, A, and Z keys. All others seem to be okay. I replaced the keyboard but have the same issue. An external usb keyboard works fine though. What could be the issue? The keyboard port?

Or the keyboard controller - but if two keyboards have produced the same result, the fix is the same (and a painful one) -- replace the mainboard.

Okay I was afraid of that. I had already replaced this system board twice. The first was because the system would not boot and just gave three beeps. I got a system board from ebay but then I had an issue where I would only hear audio from one speaker. After replacing the speakers twice with no luck, I exchange the system board for another one. The audio works fine but now I have this keyboard issue.
