I lost my BIOS password for the IBM ThinkPad. This doesn't belong to the CMOS battery – I need to remove it from EEPROM.

How can I remove it?

It really depends on the model of Thinkpad you have, how you reset/hack this eeprom chip, there is not a universal method across all models. You are better to pay a service company to do this for you. –  Moab Feb 25 '12 at 17:26

You need to use a programmable interface and attach it to the chip, then you can read out the EEPROM once you boot your laptop. Then it's only a matter of knowing where the password can be found...

An example can be found here.

Thank you very much for the above said information. Is there any other way to remove the Password because its difficult to put hardware and connect through the software and then attached another computer, it could be risky is nt? –  Syed Arif Ali Feb 28 '12 at 16:37
    
That's the only way to do it I guess... –  Tom Wijsman Feb 28 '12 at 19:20
