I purchased a second hand ThinkPad from an ebay outlet. When it arrived I wiped windows 10 from it and installed ubuntu with no issues. It runs perfect without any weird fixes needed. However, after just checking the bios to see if I could change some settings, I realised it has a supervisor password....
The password will be stored in EEPROM in newer laptops. Removing the battery will not clear the password and could make things even worse since you won’t be able to change any settings that get reset.
The best thing would be to return it and find a different one that’s not locked.
Is an unknown supervisor password for ThinkPad bios an issue if I've already installed linux?
