laptop keyboard is typing zeros "00000000000000000

Hello, My laptop keyboard is typing zeros "00000000000000000" like this by itself. I have checked that if it's a hardware issue but it's not. I have reinstalled the keyboard driver, but nothing happened.

Thank you for posting on the HP Support Community.
 

Don't worry as I'll be glad to help, I understand that your HP notebook keyboard key 0 is typing automatically, however, to provide an accurate resolution, I need a few more details:

• Did you make any changes to the settings of your PC prior to the issue?
• When was the last time it worked fine?
• Does the Zero  0 key is pressed in or damaged?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8. (Refer to the removable and sealed battery)
BIOS default:(do not skip any troubleshooting steps even if you feel steps are repeating)

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and    Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6. Follow the prompts to restart your computer. 

Hope this helps! Keep me posted for further assistance.
