Hi @Maaz12,

Welcome to the HP Support Community. 

I'd like to help!

To be able to answer you effectively, we need some information.

Have you made any changes to your OS?

Let's rollback the BIOS and check.

1) Shutdown the computer.   2) Hold down the Windows and B button together while the computer is still turned off.   3) Turn on the computer and continue to hold the Windows and B button until a BIOS Recovery screen appears.   4) Follow on-screen instructions and click on OK

Let me know if this helps.

Keep me posted for further assistance.
