Patching bios dumps and sercuity i2c remove computrace E531 / E530

[neverexisted]

Hello, I am trying to remove computrace from about 10 laptops I got in a school auction. I'm not familiar with this setup. From what I understand the actual lock resides in the I2C chip labeled U8 on this and many other Thinkpads. I buy these allot so some better understanding would be awesome. Attached are my two Bios dumps and the third P24s08 chip which is new to me. Thanks.

For models with the P24s08 or equivalent chip ,you can short 2 pins together while booting. The lenovo autopatcher will not work.

I have tried but computrace remains greyed out and enabled. Also on another model I can't even get autopatcher to work it just errors out.

By that I mean I was able to do that method with success and set and clear a password but it had no effect on computrace.

Put a blank 24c08 (or erase the existing one from adress 0x300 if you want to keep serial machine type, etc.) and rewrite serial, etc. with lenovo maintenance disk. I did that to a T430 and worked.
