BIOS System Password - Dell N5110

Hi, I need help getting the password for a Dell N5110. A friend of mine was having display problems so we tried resetting factory defaults and now we are completely locked out of using the computer.

I read on some previous posts of DELL users saying message me the details, with proof of ownership however the posts were a little dated, is this still a viable option, and in which case who do I need to message?
