lenovo t440p bios password

Re: lenovo t440p bios password

Hi, all clips are clamps it seems very well attached but maybe you are right, i will re-test using a multimeter right now to be 100% sure. Since i had the same issue with the original clip i was thinking there was something specific with this chip

Re: lenovo t440p bios password

So the connection of those HP clamp are really perfects, even by moving them it's stable. You were right about the cabling, i reverse pin 5 to 8 (i put 8 to 5). shame on me. Great thanks for your help

You're welcome.
Yes the image was good, so I was able to track the positions of the cables.

Re: lenovo t440p bios password

Now it detects properly the chip however, with the software programmer i got from the forum it's not reading properly the contents (only FFFF).

I was able to use another software (Asprogrammer) that succeed to get the data however when i try to use lenovo_autopatch it's reporting it as "corrupted" bin. I will continue investigation a few more evening and keep you in touch

Re: lenovo t440p bios password

I finally succeed to read/backup/patch with the CH341A programm v1.29. the lenovo_autopatch worked perfectly. Thanks! For un unknown reason, after i've applied the patched_bios, i was not able to re-read it the chip (empty) however i was able to re-write the original bios. Maybe a bad connection? anyway, now the sup password has gone

You're welcome.
Most probably bad contact, also you can use NeoProgrammer V2.2.0.10 with your ch341a, for best results with this programmer.

[CITA=AhorroCuenta; n1671993]Lenovo Thinkpad T440P - Volcado de BIOS ? (NM-A131)

Hola a todos.

Tengo en mis manos un Lenovo Thinkpad T440P, que estaba bloqueado con SVP. Intenté con el controlador UEFI DXE de parche automático, pero no obtuve ningún resultado.
Pero, ahora el problema a pesar de que se verificó dos veces cuando desoldé ambos chips BIOS.

La computadora portátil no se enciende. Es un FAN ciclista.

Pero estoy bastante seguro de que es el BIOS el problema, porque hace minutos funcionaba bien, antes de que sonara el -flash- del autopatcher, BIOS.

Traté de volver a poner el viejo, pero nuevamente nada.

Así que estoy adjuntando los archivos del BIOS. [/CITA]



Hola, ¿encontraste alguna solución?
Yo tengo el mismo problema

QUOTE=SavingAccount; n1671993]Lenovo Thinkpad T440P - BIOS Dump ? (NM-A131)

Hi everyone.

I have in my hands a Lenovo Thinkpad T440P, which was bricked with SVP. I tried with the auto-patcher UEFI DXE driver, but got no result.
But, now the problem even though it was double-checked when I unsoldered both BIOS chips.

The laptop won't turn on. It's a cycling FAN.

But I'm pretty sure it's the BIOS that's the problem, because minutes ago it was working fine, before the autopatcher -flash- sounded, BIOS.

I tried to put the old one back, but again nothing.

So I'm attaching the BIOS files. [/QUOTE]

Hi, did you find any solution?
I have the same problem

Hola amigos,traté de seguir las recomendaciones en el foro,
pero cuando flasheo la BIOS de 4mb y 8bm y vuelvo a encender mi computadora no me da una imagen y el ventilador se enciende durante dos segundos y se vuelve a encender y se queda así en un ciclo y adjunté mis archivos originales.

¡Gracias de antemano por toda su ayuda

Thanks in advance for all your help
