You can`t use flash programming tool,you must use an SPI bios programmer.

Hello. Please help me with this bios. I removed the bios password, but the "Post power-on password" remained. I couldn't get it out.

Re: Bios password remove 850 G3 HP

Thank you very much for your reply!
I used RCUnlocker and got a passwordless .BIN file that I flashed to the chip. I have checked the inscription and there are no errors. I mounted the chip on the motherboard and all that happens is that my Caps Lock and Power lights blink somewhat regularly.

Try this one
i had same case and this file solved the problel
feedback pls

Hello everyone. I bought an HP 850 G3 laptop from Denmark on the Polish auction Allegxx which has a password for the BIOS. I unsoldered and read the 25Q128 chip. Can I count on removing the password? Thank you

You load the original bios to see if the old symptoms still appear.
