Hi @LALITPANDEY,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

It sounds like you are experiencing issues with your HP wireless keyboard model CK-440G despite replacing the batteries. Here are some troubleshooting steps you can try.

• Check Battery Polarity: Make sure you have inserted the batteries correctly with the correct polarity (+ and -) matching the markings inside the battery compartment.
• Quality Batteries: Ensure you are using fresh, high-quality batteries. Low-quality or expired batteries may not provide enough power to the keyboard.
• Battery Contact Cleaning: The battery contacts inside the keyboard and on the batteries may be dirty or corroded. Carefully clean both the battery contacts on the keyboard and the batteries using a soft, dry cloth or a cotton swab with a small amount of rubbing alcohol.
• Pairing: Wireless keyboards often require pairing with the receiver. Check your keyboard's manual for instructions on how to do this. Usually, it involves pressing a specific key combination on the keyboard and receiver.
• Interference: Ensure there are no sources of interference nearby, such as other wireless devices or electronic equipment, which could disrupt the keyboard's signal.
• Range: Make sure you are within the effective range of the wireless receiver. Sometimes, moving closer to the receiver can help establish a better connection.
• Firmware Update: Check if there is a firmware update available for your keyboard. Updating the firmware can sometimes resolve connectivity issues.
• Receiver Connection: Verify that the wireless receiver is properly connected to the computer's USB port. Try connecting it to a different USB port to see if that makes a difference.
• Test on Another Computer: If possible, test the keyboard on another computer to determine if the issue is specific to your computer.
• Keyboard Replacement: If none of the above steps work and your keyboard is still not functioning correctly, there may be a hardware issue with the keyboard itself. 

In most cases, you don't need to use a more powerful battery cell unless the keyboard's manual specifically recommends it. Using the correct type of batteries and ensuring they are inserted properly should be sufficient for normal operation.

I hope this helps. 
 

Take care and have a good day.
