@Vijay769,

Thanks for reaching out to the HP Support Community! 🎉

I’m here to help you troubleshoot your issue and get things back on track. Just follow these steps below, and we’ll have you running smoothly in no time:

• Dirt or dust could be stuck under the keys. Turn off your device and clean the keyboard gently with compressed air or a soft brush.
• Open a word processor or text editor to see if the issue happens in different apps.
• Make sure your keyboard layout and language settings are correct.
• Go to device manager and check for keyboard driver updates or reinstall them. If you're on a laptop, test with an external keyboard to check if it’s the built-in keyboard that's failing.
• Sometimes, a recent update or app may cause conflicts, so check for any recent software changes.
• If the keyboard still doesn't work after trying the steps above, the issue could be hardware failure, and it may need to be replaced.

I’m pretty confident this will do the trick! But hey, if you run into any bumps along the way or need a little extra help, just give me a shout! I’ve got your back. 💪
