Hi
I'm afraid that you 'll not get assistance to bypass any password Restrictions in here.Yours might be a legitimate Issue, as people here provide help through online we don't have any means of verifying your ownership over that machine. The password has been set in place to restrict unauthorized access, so offering help to get around it can be considered Illegal.
In a similar situation I would contact the people who sold that machine to me and ask them for any info they can provide regarding the Restriction.
