Hello guys

I have tried all I can but I really need your help as I can't boot my T450 NM-A251 anymore

Removed supervisor password successfully and I could access bios, but could only boot my system partially (machine stopped in win 10 boot process) and restarted.

Tried to reinstall the computer from usb media (W10pro). I tried both legacy and UEFI boot options, even changed ram and ssd, no success. Black screen at loading the installation files (led activity on the usb key) then i got stuck on a stripped orange screen. i tested the screen and all hardware, no issue, all passed correctly.

I tried the Clean ME method on the patched bin file and I got a 2x 5 beeps loop but could not enter the bios then, just got error message saying: bad CRC of security settings in EFI variable , press F1 to enter setup , but F1 leads nowhere but a black screen.

I rolled back to original 1. file, accessed bios without password and I restted to defaults factory setting: the CRC message disappeared but i still could never reisntall the computer (same striped orange screen)

I checked the bin file with UEFItool and it shows last area in red, but I don't know what to do.

It seems my bios I bricked since the beginning and the password removal does not help. I put the bin here (no password).

Could anyone check and maybe fix this?

Thank's a million for your help

The bios is Winbond W25Q128FV, I used the CH341a module to extract, verify and patch with autopatch method.

After a few more days of searching, sanity-saving breaks included, and a whole lot of “what the heck is happening,” the issue just... vanished.

Yesss, really like, poof, gone. I can't explain it.

Maybe it was because the battery had been disconnected for ages, or maybe—just maybe—the blue moon teamed up with my trusty chunk of tourmaline to work some energetic protection magic?!

Long story short, the motherboard suddenly sprang back to life, and I could finally boot the OS normally.

No rhyme, no reason—just pure, unexplainable tech voodoo. I'm half-convinced the tourmaline chased away whatever tech gremlins were lurking.

But hey, I'm not questioning it!

Whether it was the universe, some mischievous spirits, or a crystal-powered intervention, I'll take the win. => let's just keep the faith )))
