Update : got a bit sick. Computer is working no problem : I had the choice to permently disable computrace (which is done ) and supervisor password is disabled with no errors thanks to MaxPower EC file . The working bios for x380 is from 4Matic (Thanks). I managed to learn a bit from the dump provided. So i am assuming that computrace are those two 60 on adress 00000200 which needs to be zeroed out in order to have the choice to remove computrace. Supervisor password is disabled from zeroing out from adress 00000210 to adress 00000230 approximatively (I uploaded a binary diff between the original...

Sorry for bothering , I forgot that i have a taken a photo of the bios menu with all the information before doing the shorting method to bypass password. The problem may lie between the bios chip and the EC chip. Is it possible to get a bios bin and EC bin please ? Thank you in advance

Hello MaxPower,
Thanks again for sharing this method. I tested on my laptop but it is high risks, high reward solution . It was a lenovo x380. Of 50 tries on shorting LPC_AD 0 to GND, I managed to get to 2 times in the bios. On the first time, i cleared the Supervisor password and cleared the security ; I have done Ctrl+Alt+Del to exit from bios ; Upo rebooting the bios password was still there. So i managed to get bios a second time. but this time laptop froze when i was redoing clearing supervisor password; It shuts downs ; upon powering on, There was no display not even Lenovo Logo :...Leave a comment:
