What to do if Keyboard not working on HP Laptop (opens in new tab)

I am experiencing an issue where the keyboard on my HP laptop is not working at all, and I am unsure what steps to take to fix it. The keyboard was functioning normally earlier, but suddenly it stopped responding, and I have tried restarting the laptop without success. I am looking for troubleshooting tips or solutions to get my keyboard working again so I can continue using my laptop without issues.
