Re: How to reset bios Password by shorting ThinkPad T420s chip?
I dont remember where i have found it, and the notebook is already sold..
Try to find those pins on the motherboard (highlited with circle), or look for Q97, R541 numbers. I remember, that this chip was under black protective tapeLeave a comment:

I found out and dealed with the problem by myself. For greater [COLOR="green"]safety[/COLOR], use grounding.
Just find chip [COLOR="Red"][B]U22 [/B][/COLOR]and [B]short the legs[/B], which are highlited on the [U]picture 2[/U].
Hold the short [U]before [/U] you press the power button. Now holding the short, press "start" button on the laptop.
After pc starts, keep pressing F1 to enter in Bios. [U]Dont hold it [/U] after you enter into the Bios.
After you done...Leave a comment:

How to reset bios Password by shorting ThinkPad T420s chip?
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...... -
