Keyboard and touch pad not working

Keyboard and touch pad not working

I replaced the screen and hinges on this laptop model and once I started it back up, the keyboard and touchpad did not work. Both works if I go into the bios, but despite diagnostic tests, it still does not work. I read about Windows updates and keyboard not functioning. Drivers appear to be updated. Followed all checks through HP. I did test of keyboard and 1 key did not work (prnt scrn key). Will replacing the keyboard (HP Part # 807526-001) resolve this problem? Laptop keyboard worked fine before changing out the screen/hinges. I can also use USB keyboard, and touchscreen works. Any advice would be greatly appreciated.

"If the keyboard works fine in the BIOS settings screen then the problem is a Windows driver so . . .

go to Device Manager and uninstall the keyboard and reboot.

Now something you said is not clear.

“Both works if I go into the BIOS, but despite diagnostic tests, it still does not work.”

You are saying it works and it does not work. Diagnostic tests don’t fix anything they just alert you to problems.

So did the keyboard pass the diagnostic test? If yes then it is a driver issue.

What changes if you press the <Num Lock> key?"
