Keyboard strange behaviour (starts working only after Regedit run)

[alexjob2000]

I am already a year trying to solve following strange problem - after Windows 10 starts and I see desktop, I can press any keyboard key only once and after this my notebook keyboard never responding.

But if I run Regedit once - just run it without doing nothing and close it - my notebook keyboard start work fine, with no problem, all keys are working, until Windows restart.

What it could be?

Also I see in UEFI Bios only ESC and F1-F10 keys are working and arrows are not working. Also when I run UEFI test - keyboard test - most of keyboard keys are not working.

With external USB keyboard everything works fine.

So its hardware or software problem? Defected integrated keyboard? I updated BIOS to current, reset CMOS - no result.

But strange that it working well after Regedit run in Windows.

Thank you for posting on the HP Support Community.

I appreciate your efforts to try and resolve the issue. Let's try uninstalling and reinstalling the keyboard.  

1. Shut down the computer.

2. Press the Power button, and then immediately press the Esc key repeatedly to open the Startup Menu.

   NOTE: If the Startup Menu screen does not open, the integrated keyboard hardware is not working. Service or replace the integrated keyboard in the notebook. To continue using the notebook, connect a USB wired keyboard to a USB port, and then restart the computer.

3. Press F10 to open the BIOS settings.

4. Press F5 to load the default settings, and then press F10 to accept the changes.

5. Restart the computer.

6. In Windows, search for and open Device Manager.

7. Click View, and then select Show hidden devices.

   

8. Click the arrow next to Keyboards, right-click the keyboard name, and then click Uninstall to remove the device from Windows.

9. Remove all devices in the Keyboards category, and then restart the computer.

   The keyboard should now work correctly.

Hope this helps! Keep me posted for further assistance.
