Forgot password to Lenovo thinkpad x220?

Added (1). Hello, I have a lenovo thinkpad x220 that was given as a gift from the previous company I worked at. I have the supervisor password and the power-on password, but can't seem to figure out how to bypass the set password for the account. I haven't touched the computer in years so I doubt there's anything important. My question is, is there a way to factory reset this laptop with the credentials I DO have?

Thanks.

Added (2). EDIT: The OS is windows 7 enterprise

The logon password for the OS? What OS?
