bios pass is in MEC1653, if you don't have SVOD4 or RT908H you can't read it. You can use Maxpower3 method, described here:

Ok thanks for your kind response. By the way how do you say directly it’s in that chip? Why could not i identify it? I thought bios password always in the winbond 128MB or 256MB chip.

Bios patching work on 16 Mo, but 32Mo not Work.
Password is always in EC Mec/ITE or Nuvoton etc .. on Thinkpad

Ok thanks a lot. What is mine? 16MB or 32MB?

[Maxpower3]

Winbond 25q256 = 32Mo

[Muditha Folini]

Winbond 25q256 = 32Mo

Ok, thanks sir. Therefore your method is not working for me. I have to try with the svod 4. Really appreciate your advice and helping me to improve my knowledge related to this.

LPC Bypass should work on this. Just the BIOS patch isn't working.
Look for the LPC1 connector on your motherboard.
I can't find the schematic for your model.
And follow the information in the EC BYPASS post.
Use one of the lad (0,1,2,3) and GND.

Ok sir. Actually I need a proper help for this because I am not an expert if I do something wrong then whole thing will be damaged. If I contact you can you guide me? I live in Switzerland. Sir do you live in France? Because in Switzerland there’s no chance for repair this kind of stuff.

Sorry for your misunderstanding sir. I didnt mean it bad way. I wanted to ask you how you recognised it directly? By knowledge or experience? Because i still can not. Thats what i meant. Sorry if i bothered you but you helped me and suggested me maxpower3 and he told me lot of things. Please dont take it wrong way. Thanks
