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.
I contacted the seller and they gave me a few to try but they haven’t worked.
They said their tech will be back next week and will contact me then but I may have to send it back.
My question is, will this be an issue in the future? Or does it depend on which settings are locked?
I don’t really want to send it back unless it’s critical, as I have a lot of work to do and my previous laptop is moments away from death.
You can either try to contact the seller and ask for the password or just erase the UEFI settings by shorting some jumper or something. There should be instructions how to do that for your specific model.
