S400 original BIOS file - BIOS Recovery

hello community !

 

I have tried to update the BIOS of my ideapad s400 with a modified BIOS file. (follow this link).

 

Unfortunately this update did not work and my laptop doesn't start by pressing the "start button". Moreover the "Recovery button" doesn't work either.

 

 

Since this point I have googled a lot and found some opportunities:  By pressing Fn + R + Power Button and plug in AC I am able to start a BIOS recovery boot (without GUI, only loading USB)

 


My concret problem is: I don't have the original BIOS file (6dcn20ww version1.6) and at the lenovo download site there is no BIOS download option....

Could somebody help me please?

 

 

Thanks !

Hi Dominik1234,

 

Welcome to Lenovo Community

 

Unfortunately, there is no available link to download your original BIOS version. So in this case if your machine still is under warranty the only way is to send it to the Service Center.
