Funny story, I bought a system board on eBay that had a BIOS password on it. The seller didn't answer my messages asking for the password, so I assumed he knew there was a password, but didn't know it (and didn't say in the item description). He just ghosted me. Returning it seemed like a hassle, I really needed it and this was the only one on sale in Europe. Found the former owner of the laptop where the board came from thanks to the corporate/user name displayed on the password prompt. It was a small IT company. Contacted them on LinkedIn asking for the password and detailing the situation. Didn't get the password, but the CEO/owner of the company certainly had a surprise. Turned out one of their guys was selling parts from their laptops/hardware without permission. Suddenly, the seller on eBay found the message feature and wrote to me, saying I got them in trouble. Shouldn't have ghosted me, then? Just a "sorry, didn't know it had one" and I would've just proceeded to replace the BIOS chip, which was my plan B and it's what I ended up doing.
