Fujitsu Lifebook Forgot Password

I just discovered my old Fujitsu lifebook that's about 13 years old. (P-Series) I also discovered that I totally forgot my old password. I have no revery disc. I tried f12, and esc, and looked at all of the settings wherein. None of them helped me. Is there any way to reset, disable, bypass, or recover the password?
Thanks!
