@Lincoln5307 Welcome to HP Community!

I understand that some keys are not working.

Do not worry, I will try to fix the issue.

Please let us know have you tried with the wired keyboard?

Please perform the keyboard test and let us know the result.

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.

Keep us posted,
