@abbashaz

Welcome to the HP Forums. I would be happy to help you with your HP ENVY Notebook 15-as050sa. I understand that you are getting high pitched noise from the notebook and you have already done some preliminary troubleshooting. 

Don't worry though as I have a few steps to determine the issue and find a solution as well,

Download the bios using a flash drive from another computer and update it once again.

Restart the computer and check if the issue is fixed.

If the issue persists, that should be hardware issue.

I request you to contact HP Phone Support for service options.

Let me know how it goes.

I hope it helps and if you feel I have answered your question and concerns,

Please mark this post as a solution accepted and Kudos would also be appreciated.

Cheers.
