LIFEBOOK E8020D SECURITY PANEL

I have Fujicu Siemens LIFEBOOK E8020D. It have Security lock that is preventing computer to turn on.
You have to type numerical password to turn on, that I don`t know:(
I thought that this information must be in main bios Eprom. It`s SST49LF008A.
Is there any way to reset it to default or someone have diferent solution to this problem.

P.S. I put this topic in BIOS problem section but it can be also in Notebook repair section if someone have diferent solution then BIOS...
