Hi MValente88,
I suspect it is the Operating issue.
Please check the behavior connecting an external keyboard.
Check keyboard functionality in Command prompt. For that restart the system and at the Dell logo tap the F8 key every two seconds. In the ‘Advanced Boot Option’ window using down or up arrow key highlight ‘Repair your Computer’ and hit enter. Select the keyboard layout and click on ‘Next’. On the ‘System recovery Option’ menu click on ‘Command prompt’ to open it.
Use your keyboard in this window to check if it works fine. In case the keyboard works fine, the issue is with the Operating system. You may have to back up all the data on the system and reinstall the operating system. If the keyboard does not work even at command prompt, you may consider replacing the keyboard.
