Hi @venkataramana18,

Welcome to HP Support Community.  

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

If the buzzing noise is not coming from the laptop's speakers or fans, it's possible that there may be an issue with the hard drive or other internal components of the laptop. Here are a few steps you can take to try to diagnose and resolve the issue.

• Check for loose components: Sometimes, buzzing or rattling noises can be caused by loose screws or other components inside the laptop. Make sure all screws are tight and that there are no loose components inside the laptop.
• Run hardware diagnostics: Many laptops come with built-in hardware diagnostics tools that can help identify any issues with the laptop's hardware. Check your laptop's documentation to see if there is a diagnostic tool available, and run it to see if any issues are detected.
• Check the hard drive: A failing hard drive can sometimes cause strange noises. You can use a hard drive diagnostic tool such as CrystalDiskInfo or HD Tune to check the health of your hard drive.
• Update drivers and BIOS: Sometimes, driver or BIOS issues can cause strange noises or other performance problems. Check the HP website for any available updates for your laptop's drivers and BIOS, and install them if necessary.

I hope this helps. 
 

Take care and have a good day.
