Chosen Solution
I work at a school where a student has set all of the BIOS passwords on a Lenovo Thinkpad E431 (Type 6277-5AU). I have removed the main battery and the backup battery and cleared the Power-On Password, and I can now get into the BIOS setup and see that the passwords are set, but can not clear or change the passwords. The Lenovo manual indicates that the motherboard must be replaced. From the Manual “If you forget your supervisor password, Lenovo cannot reset your password. You must take your computer to a Lenovo reseller or a Lenovo marketing representative to have the system board replaced.” Can some one point me to a set of instructions (preferably with pictures) to clear the passwords on a Lenovo Thinkpad E431. Thanks.
I found this on the Lenovo Support site. It says that you only have to replace the Motherboard if the supervisor password is set..This will not let you into the bios….you have access to the bios so this may help. Link to Support Page: https://support.lenovo.com/us/en/documen…
