Computrace on older Lenovos

[RethoricalCheese]

What is the best way to remove computrace on older lenovos like T410, T420, T430, X220 etc?


I guess rewriting L08 but if so, what part of it needs modifying?

Did you find a solution?

I unintentionally activated the computrace by doing tests.

No computrace originally on it.

I put back the files of the 2 Bios chips and also of the RF08
but nothing changes. Still blocked.

The funniest thing is that I tried to answer this post to find a solution ^^

Re: Computrace on older Lenovos

Excuse my ignorance, but can't computrace be disabled permanently in bios settings?

Re: Computrace on older Lenovos

no it's grayed out now and message at startup. I didn't have message before touching the 24ps08 (enable "not activate")
put back as original it changes nothing (25q32 & 25q64 + ps08)

Re: Computrace on older Lenovos

but can't computrace be disabled permanently in bios settings?

In order :

I was in "enable (not activate)"

I have set to disable (I have saved)

then I put in "disabled permanently"(the window has become grayed out in "disabled" no more modification possible, it's normal.)save also

I inject reading of original ,think to find enable (not activate)

and from there I have the message: this pc is protected by absolute every time I want to enter the bios.
I then inject original of 2x 25Qxx +ps08 and always the message in red after F1

Re: Computrace on older Lenovos

here bios yoga 12 Model :20C0 ZIPS1 LA-A341P


edit :
there is not a Solution for SVP Password for these models? see photo 3
it's almost the same motherboard but not same

ZIPS3 LA-A342P
No MEC16
No 24PS08
just 25Q32 and 64 and ENE 9012QF

@Knucklegrumble your patch does not work on it

edit n°2:
even without the 24ps08, the bios see always computrace. he does not see serial number etc .. But it's normal.

Re: Computrace on older Lenovos

it's good, it works.

After starting without the 24Ps08, I put the last version permanently disabled.
And the Computrace message disappeared.
With option in the Bios "enable" but not Activate

You can permanently disable it in FIT settings when cleaning the ME firmware

Ha ok,
I'm a little lost with IntelMe
I go read it at Winraid to understand tools and everything that goes with them.

What is your tool? I don't know that?

I modify and compare each byte to find the functions! you are cheating
