Keyboard Keys not working
Hi, I have an inspiron 15 3567. I'm facing a strange problem. Some keys of the keyboard aren't working like "b","n", space key, down key, left key, right key.
I have changed the keyboard but still, those specific keys are working. I'm using windows and Ubuntu with dual boot, and those keys don't work on each operating system, so I don't think that it will be a driver issue. On screen keyboard works fine.

Go into device manager uninstall keyboard and driver and restart PC. Let driver install again and see if keyboards works correctly. If not then the keyboard is either contaminated with something causing some keys not to work. Or the keyboard simply requires a replacement. If you believe nothing has been spilled on the keys I would try compressed air in a can to see if you can loosen any debris that worked under keys.

I doubt it is a coincidence that I am also having problems with the "b" and "n" keys on my XPS 12. I had just removed Windows from the machine and installed Ubuntu. Did anyone find resolution on this issue?
Exact same problem here:
Dell Inspiron 15 5510/5518 - "b","n", space, down, left, right keys not working, despite uninstalling the 2 keyboard drivers “HID Keyboard Device” and “Standard PS/2 Keyboard” followed by restart, several times.
Once in a while - randomly - all of those keys would work again for a while. It is usually all or none of the above group working or not working at the same time.
Strange that only those few keys would be affected if the flat keyboard connector to the motherboard got loose?
How did you fix it?

Same here. Suddenly my M, N, U, and Y keys aren’t working.
