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

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

Since the touch pad and keyboard doesn't work but a USB mouse does you might need to get or borrow a USB keyboard. I've never been in favor of using a BIOS passwork, there's 2, one for starting the computer and the other for making changes to the BIOS.

As for removing the battery you also need to have the AC power unplugged at the same time. In a dire circumstance once could open up the Notebooks case and remove the onboard CMOS/BIOS battery for a few minutes that will take out the BIOS password but that also takes out any user settings. There may also be a CMOS-clear jumper on the motherboard.

Overall, what you describe is reminiscent to a group of Notebooks given to our church that came from a company network that did not first have the passwords removed, same process was needed on each.

I tried plugging the external keyboard in to different USB ports and found one that worked, so I'm able to log in and use the computer. But how do I get the laptop keyboard to work so I don't have to lug around an extra keyboard?
