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

Disabling laptop keyboard

Hi,

Thank you for posting your query in Microsoft Community.

As per the description. Let me help you in resolving the issue.

I suggest you follow the steps below and check if that helps:

• Press Windows + X and select
  Device Manager from the list.
• Find Keyboards in the list of devices and click the arrow to expand it.
  
• Right-click on the internal keyboard and click Disable. If there is no Disable option listed, click
  Uninstall.
• Click File>Exit. Your laptop’s internal keyboard should now be disabled.

Note: If you had to choose Uninstall instead of Disable in step 4, the keyboard will be automatically detected and re-installed if you ever have the Device Manager scan for new hardware for some reason. If that happens you’ll need to repeat this procedure
in order to uninstall it again.

Hope the information helps. Please let us know if the issue persist and we will be happy to assist you further.
