Changes/reset Bios password

[Masud__]

Hello Everybody,
I hope all of you are doing well.
I have a laptop HP Probook 440 Go. with a Windows Operating system 64 bit. I forgot my BIOS password. and it is locked. The laptop warranty is expired. there is no support from HP. I would like to change my BIOS Password and update BIOS. I have tried some solutions for that like, CMOS removal but did not work.
Would you please help me to give some possible solution? so that I can get rid of it.

I appreciate your help and time.
With best wishes,
Masud

Removing the CMOS battery does nothing to reset passwords on laptops.

For BIOS or power-on password resets, because the password is encoded onto a chip on the motherboard, replacement of that motherboard is required. HP does not reset the BIOS password on the current motherboard.

If you are not prepared to spend the money to get HP to replace the motherboard, you would have to take the PC to a local repair facility to see if they can do it for you -- but we can not assist in that in any way.
