Hello, There is no general password. Laptop owners can choose to set one if they want however when buying a used system the seller should give you any password you need to access the bios or startup the system. Dell can help in unlocking a system but you will need to pass ownership verification.
I am buying a used laptop and just working on it like learning and doing my own work. I don't do anything but don't understand why it's bios asking password. If there is any general BIOS password of BIOS in Dell laptops kindly let me know. I read all the dell community but unable to find out my solution. Kindly let me know. Thanks
