Hi @tinakar,

Welcome to HP Support Community. 

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

I see that you are facing blank display issues with your HP Pavilion - 15-Cc166tx.

Please follow the steps listed below for BIOS recovery:

1. Turn off the computer and keep the power adapter plugged in.

2. Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.

3. Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.

4. The HP BIOS Update screen displays, and the recovery begins automatically. Follow any on-screen prompts to continue the start up to complete the recovery.
