hp 840 g8 bios password proplem.lock please help

Hello badcaps family. I have the rt809f bios programmer. I need help for my HP 840 G8 laptop. There is a password in the bios. That's why I can't do anything. Can I write bios or ec with rt809f? Please help. I need your ideas.
I removed the bios chip, but I do not have a bios device to write this. What can I do? What device do I need to buy to write the rt809f bios?
