Use the tools mentioned with your original bios backup.
If you use a random bios from somewhere else you can have problems.Did you check the alisaler bios BID to make sure it was the right one,was the ME firmware initialised or configured.If you don`t know how to check any of those things don`t go looking for a random bios.Leave a comment:

Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

Dear All,
Hope that this post is at the right place of the forum.
I am seeking help and technical advice to remove bios admin password from HP ProBook 4520s.
The laptop is operating normally and, I am not facing any major issue with it except; the bios admin password that I found about by coincidence only few weeks back.
As the laptop is operating normally, I am reluctant to take it to a workshop to de-solder the bios chip in order to read it by an external programmer, as I am not an expert in doing such a thing.

Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows
