I have an issue with supervisor password on my Lenovo Thinkpad X201t. I've read the eeprom content, but i don't know how to extract the password, i believe it's encrypted.

on address 0x330 and 0x340.

I've attached the eeprom content.

Could you please help me to clear the password.



I have Thinkpad T510, i use pinout from https://www.allservice.ro/forum/images/t510.jpg. But while trying read eeprom it returns !!! Error !!! Reading Eeprom failed! After powering on PC there is some voltage on SCL is this correct? Have someone full scheme with voltage stepper?
Thank you in advance
