lenovo ideapad s400-9630 system password

[karankumarr]

Hi

This will be my first request on this forum,

I have a reapair shop in london Uk, recently received a laptop for repairs

 

model is lenovo ideapad s400 9630

 

it has a system password, cant go into BIOS settings etc

 

I have already flashed bios from a file i downloaded from here, still the system passowrd is there

 

I wonder is the password is stored somewhere else on other IC

 

let me know if you can help

 

thanks a lot

Karan, did you used a external eprom writer with the file downloaded yesterday?

[karankumarr]

yes i have

gq-4x and also tl866

 

i flashed  it

 

i think so lol

 

May be i m missing something

Post to me the link of file that you downloaded yesterday... and put the board model in topic title, like that: BRAND - MODEL - BOARD ID - Problem, please. Its the rule of a new topic.

 

And do you have the schematics for this board?

[Perciva]

alguns Lenovo usam um chip especial somente para armazenar a senha de BIOS, tornando assim a remoção bastante mais complexa. voce já tentou algum tipo de remoção de senha via software?

 

some lenovo uses an special chip just for BIOS password, making removal a bit more harder. did you tried some software bios password removal?

[karankumarr]

OK Bruno

I will put the model number an rest of the things next time

 

i do remember that levono i have come across sometime back they did use a different chip to store a system password like perciva said

 

the link of the file i cant find anymore here but my model is ideapad s400-9630 

 

i will put a pic of a IC i think i doubt that it stores a passowrd as i have seen it earlier before

 

thanks

I downloaded the same file and inside of the rar exists 2 bin files, one of 2MB and other of 4MB. Did you write both of them in your board?

[karankumarr]

yes wrote both of them

 

on these IC

 

check the link

 

 

I read both the bios for backup and both of them are 2mb in size, do u think its possible

Perciva, alguma idéia?

 

Perciva, any idea?

 

 

[Perciva]

Por favor, preencha os dados da placa mãe, assim como Brunofariassilva escreveu para você.

Assim nós podemos baixar o esquema e analisar este chip

 

 

 

please , fulfill motherboard data, like brunofariassilva wrote to you.

 

So we can download the schematic and analyses this chip.
