So, I boot up my laptop and notice I can't type my password in, so I log in with my fingerprint, I open up notepad and notice that my 4 5 R T F G V B, Left Shift, and Left Ctrl keys all don't work. I also noticed that they're all keys that are staggered vertically (with the exception of the modifiers).
I went to a keyboard tester site to get a visual representation of the keys that don't work.
Notice the chunk in the middle of unhighlighted keys.
I've taken my laptop apart before, so I pulled out the keyboard and inspected the keyboard connector and socket and found no tarnishing, bent pins, etc on them.
Is there a way to diagnose if this is a keyboard or a motherboard issue?

It is almost certainly a keyboard problem. There is a matrix of contacts in the keyboart and I am guessing to column connections have failed.

There is no way unless you try a different keyboard or try your keyboard on a different machine. T410, t420, t510, t520, w510, w520, x220 are all compatible, plus some others.
