locked lenovo T520i

[rookieme]

Hello,
I have a lenovo T520i locked with supervisor password.
Anyone can share a bios dump in order to try it?
I'm not sure if I can bypass it with a new bios dump but I'll give it a try.

The first one worked but didn't unlocked the system.
It seems it also has a TPM chip that stores that information.

Re: locked lenovo

oh, that is what i was afraid of...
is there any other eeproms? if there are, maybe you could dump it so that i could take a look but i doubt i can be done without dump from unlocked laptop

@khaahk
T520i model is a bit different from T520 so the TPM chip is not the same or is not at the same place.
Here are some photos.
Also I'm not sure if my bios programmer is capable of reading that kind of eeprom.
