Need some info with Thinkpad T440

[shippy]

Hi, I received 3 T440 with their BIOS dead. Successfully reflashed them, they power on and everything.
Problem is I get a "bad crc in security settings in efi variable" and it forces me to enter BIOS setup. The owner doesn't know the Supervisor password because he bought them out of auction from a dead company.
I don't care about finding out the password...I just need help with bypassing that error so it can boot on it's own, into it's own operating system.
Did anyone manage to do something similar? If it's possible to make the laptops skip that error and just boot on it's own, please share...I'm out of ideas.

Thank you!

You must go to BIOS settings, then go to Security page and set SECURITY CHIP to ACTIVE. Works with E540, but I think your problem is the same.

Thanks for the reply! The problem is they are all with Supervisor passwords.

I can't enter the BIOS. And these things have all security details on another chip. The owner doesn't know the passwords, as he bought them off auction.
And because of this error it forces me to press F1 to go to BIOS settings and the Password Prompt pops up.
I'm trying to find a workaround that error so it can boot into it's own OS. And resetting the passwords is almost impossible on these models as only one Service can do it, and they charge a lot...but if there is no workaround I'll probably have to tell my customer to contact them

Also he has a fully working one that has a supervisor password too, but it didn't have BIOS problems so it just boots up into Windows.

I think that reflashing the BIOS activated this error.

And it's frustrating because I made the laptops turn on and function again...except the fact that it won't boot past that error because of the password prompt...and I'm stuck
