[SpencerWinson]

Sup everyone. 

Have problems with F2-F3 buttons. They are using to make screen brighter. With other F's buttons everything is ok. 

How can I fix it?

@SpencerWinson Welcome to HP Community!

I understand that the F2-F3 button not working.

What is the product number of your computer? (Ensure you don't share any personal information such as serial, phone number, email ID, etc..). 

Have you tried with an external keyboard?

Please 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.

Keep us posted,
