Hello
Have a supervisor password on the bios... Is it possible to somehow short the chip? I found out, that the bios is located here.. (look the attachment) Googled that it shoud be done by shorting of SCL and SDA.. and it works with T420... So is it possible to do the same with T420s? Sending you the shematics, which i found from the service manual of T420s...... -
