Re: hp 450 g7 password
Try. it will enter in MPM mode, press F10 and you have a tab under "Main" named " write machine unique data" and you'll find all data on stickers of back of the bottom cover. to exit MPM mode use BCU 4.0 under windows or restart laptop how many times counter shows.Comment

Hi everyone,
My name is Ricky and I'm a repair technician/enthusiast. I've been learning a lot from this community and have successfully done some basic BIOS unlocks in the past, but this particular modern HP model is giving me a really hard time!
I need some help manually removing the BIOS administrator password from this machine.
I have already tried using the "HP G9 Unlocker V3.0" on my 32MB dump. I successfully bypassed the U68 Sure Start chip (SPI NAND) by isolating Pin 8, preventing the auto-recovery. The machine boots and bypasses Sure Start,... -
Hi everyone,
I have a Lenovo FT491/FX390 (motherboard NM-B891 REV 2.0) with a BIOS password that I can’t bypass. I’ve tried the usual methods (CMOS reset, jumper, etc.), but the password persists.
What I need:- A clean BIOS dump (without password) for this specific model.
- Or, if possible, help to remove the password from my current BIOS dump.
What I can provide:- A full BIOS dump (W25Q80dv or similar) if someone can guide me on how to extract it safely with an RT809HSE.
- Any additional info or photos of the board if needed.
I know the community has tools... -
Hey guys,

Before i write the Serial NR.etc i wanted to say that strangely after flashing with 3 different Bios dumps and one from lenovos site
the laptop works but everytime it wants me to type a supervisor password i never set.
I thought the supervisor password is stuck in the ec bios but no it isn't either because after replacing the ec chip from one of another board it still has the supervisor password.
Anyway i wanted to ask what of the two chips is the ec bios because on the left...
