HP Pavilion Notebook 15 Laptop Keyboard Is not working or typing

[areli_pavillion]

I have the HP Pavilion Notebook 15.6" Laptop au030wm bought in 2016. On Saturday, I replaced the battery in my laptop with a new one. I turned on the computer to make sure it was working. Everything was fine. I accidently turned off the laptop by pressing the power button. I turned it on again and the keyboard was not working. It did not want to type in my password at all. So they keyboard isn't working or typing at all. It's almost as if it's completely dead. The touchpad and power button work just fine. A USB external  keyboard works fine too. I've already tried all the basic solutions like trying to unlock the keyboard, pressing ESC, updating keyboard drivers, uninstalling them, windows updates and updating windows 10, but nothing works. Can someone please help me for an ASAP fix? I'm a college student in the middle of the semester that needs their laptop working ASAP.

@areli_pavillion Welcome to HP Community!

I understand that the keyboard is not working.

Please perform the below steps and check.

Hard Reset:

1) Shutdown the computer.  

2) Unplug all the Adapter and peripherals connected.  

3) Remove the Battery. ( not for Built-in Battery computer ) 

4) Press and hold down the power button for 15 to 20 seconds.  

5) Plug-in the Adapter and put the Battery back into the computer if it's a (removable battery)

6) Try to turn on the computer and check, If the issue persists continue next step

Set BIOS default and restart:

1. Restart your notebook.
2. During startup, press F10 repeatedly until the BIOS menu is displayed.
3. Once the BIOS menu is displayed, press F9 to restore factory defaults.
4. Select Yes to confirm.
5. Press F10 to save changes and exit.
6. Select Yes to confirm.
7. The computer restarts using the default settings.

In that case, I would suggest you perform the keyboard test and let us know.

1. Power off the PC and make sure that it is completely powered off.

2. Press the power button and the moment you press the power button immediately start tapping F2 key, you should see the system diagnostics screen.

3. Look for the component test, under that all the hardware will be listed, please choose Keyboard and initiate the quick test.

Note: If it fails it will generate a 24 digits alphanumeric failure id, please capture that.
