Hi@svmvnthvlize, Welcome to the HP Support Community!

I understand that notebook has an issue with the keyboard.

It looks like you are having issues with the Keyboard on your Notebook.

We will surely assist you with this.

Let’s start with a question:

1. Was there any liquid split on the Notebook Keyboard

2. Is there any Dust settled on the Notebook Keyboard

3. Are there any Keys which are fallen off / Any Keys which are loose

4. Check for BIOS update?

Troubleshooting Steps: 

Step 01. Click on the Start Button and go to Control Panel

Step 02. Open the Device Manager and expand the Keyboard from the list

Step 03. Right-click on Standard PS/2 Keyboard and click on Uninstall

Note: This driver will get installed again automatically on your Notebook

Step 04. Please turn OFF the Notebook

Step 05. Un-plug the Power/AC Adapter and also remove the Battery too

Step 06. Press and hold the Power Button of the Notebook for a full minute

Step 07. Now let's re-insert the battery back in and plug back the Power/AC Adapter

Step 08. Start the Notebook and keep tapping the F10 Key during the startup to access the BIOS

Step 09. Once you get to the BIOS, Please press F9 or F5 Key[Model specific] to load setup defaults for the BIOS

Step 10. Use the arrow keys to say "YES" and hit enter

Step 11. Now let's press Esc/Escape Key. Save Changes and Exit - Yes

Step 11. Now please wait till the Unit loads the Windows Operating system

Or

Please check if Sticky Key is turned ON by any chance

Please press Shift Key 5 times and turn it OFF if it is turned ON by any chance

And

If the issue still persists please check and verify if an External Keyboard works fine with your Notebook
