LENOVO T14 Gen1 NM C931 MEC1663 Bios Password Removal Two minutes to Bypass

[@raphaalvesdasilva856]

Thank You for the information, i did short motherboard nm-c931 in j9301 pin 8 and 10 with a cable to usb GND. Work Good

[@JFIXX1]

Thanks for sharing and all your work i have just subscribed. I currently have a T14 Gen 1 with motherboard version NM-C931 which appears to be the same as yours. I am trying to remove the security password as demonstrated in your video. I am not able to see clearly enough on your video on which pins you are shorting. I have tried disconnecting the CMOS battery and i also tried shorting the Winbond BIOS reset pin to ground but password remains. Im thinking the password may be stored in the EC chip not the BIOS chip. I have downloaded schematics and boardview but i am new to reading these types of diagrams. Could you help me as a beginner to understand where i need to short or inject voltage to reset my EC chip to remove my password. Thankyou in advance if you can help

[@paulomurillo7110]

Is there any tutorial on how to access the bios of the T14 3gen??

[@Linux-User925]

Hello, thank you for the interesting video, it would be nice to know which point you short-circuit to reset the password. Unfortunately no further description in your video.

Bonjour Max, Je ne peux pas modifier les paramètres dans le bios Passwor supervisor ... Mon portable est un Thinkpad P15s G1 avec carte mère GT4A0 NM-C931 Impossible de trouver la puce, est il possible de faire un bypass ? Je pense que le bios est sur la puce MX25L25673G... Tu es ma dernière chance ;) Merci d'avance Alex

[@AlexVlb]

J'ai bien trouvé J9301 sur la carte, sur le schéma tu indiques que la borne 3 et 12 sont à mettre à la masse au moins mais sur ta vidéo tu touches seulement une borne avec la pointe de touche, je ne comprends pas ... Merci

[@AlexVlb]

j'ai essayé de mettre 4-6-8-10 à la masse mais échec :(
