laptop keyboard and touchpad not working

Problem: computer starts up normally and goes to the password log-in screen, but nothing happens when I try to enter the password. The computer doesn't appear to see any keystrokes.
Solutions tried:

1. rebooted
2. removed and replaced main battery
3. attached USB keyboard
4. hit Enter key on startup: successful in opening the Advance Options menu, but am unable to take any of the actions because all require that I enter the laptop password
5. looked for an onscreen keyboard, but there isn't one because this isn't a touch screen computer

Why I think this is a Windows issue:

1. the computer recognizes when I hit the Enter key on startup
2. the USB keyboard doesn’t work
3. the keyboard touchpad doesn’t work, but the attached USB mouse DOES work

 

Laptop and On-screen Keyboards Not typing

My Laptop Keyboard and on-screen keyboard are not "working", it does show on the on screen keyboard that the keys are being pressed when I press key, but for some reason I can't type my password, in short the keyboards work for anything except typing my password so I can log in, any help?

 

Keyboard Not Working on Laptop--Except for Password on Lock Screen

I really hope somebody can help me with this! The strangest thing just happened. I carried my open laptop to a different room, and then when I tried to type, nothing would show up and my laptop began making strange clicking sounds.

I rebooted the laptop to see if this would fix the problem. On the lock screen, the keyboard works to allow me to type my password in to enter the laptop. However, once I am at the desktop, the keyboard will not function.

Does anybody have any advice or a solution to this problem? The laptop is only a few months old. It is a Windows 10 Dell Inspiron Notebook.
