|For desktop systems there are many so called "master" passwords but this is not the case for most laptops built in about the last 10 years. To the best of my knowledge there is no such password for most laptops. Even if such a password existed no responsible individual would even consider revealing it on a public forum.|
In many cases a password can be generated from the service tag. But the method of doing this, for obvious security reasons, has never been made public by manufacturers.
For many people the security of the data in their laptops is of critical importance. I consider maintaining this security to be of much greater importance than the convenience of people who forget passwords or who buy a laptop from people who do not supply them.
Sorry, but I cannot help you.
