T440p Bios Password Reset Help Please

#1 Post by Smudger1767 » Mon Apr 20, 2020 4:42 am

Hi everyone,
I’ve just got myself a think pad T440p but the bios is locked so I can’t get access to it to make changes. I’ve noticed that there are plenty of YouTube videos showing how to fix this with most of the other think pad models but not the T440p.
Any help would be much appreciated. I bought it to upgrade so I have some tinkering knowledge.

5. Passwords: Discussion on how to defeat the **password or Security Chip on thinkpads specifically or lenovo/IBM branded computers in general will NOT be allowed. The structure of the security system and how to best secure a thinkpad, etc. is allowed as long as it does not touch on bypassing such security systems. The judgement of the Admin or Moderator in this regard is absolute. There is no appeal except to the Admin or Moderator involved should your post be deleted or moved out of sight.
** EXCEPTION to this rule: Power-On passwords can be cleared as explained below by Lenovo:
http://support.lenovo.com/en_US/detail. ... migr-59377
thus discussion of power-on passwords IS acceptable and not covered by this rule.

Youtube movies no longer apply for this.
In your case you must use an SPI serial flasher.
With that, read out an EEPROM into a file, remove the password from that file, reflash that file.
(easier said than done).
That is as far as we can go here.
