If that's a bios password, you can reset it by clearing the bios, (however it being a laptop, you might find it a real chore to find the jumper for clearing the bios).
Try giving a shout to IBM and tell them your problem, they probably can tell you what you need to know. Good luck!
I maybe able to help you out, I found a way to get your BIOS Password without going though too much trouble. I have made a web page with information on this. Here it is : http://ibmpassword.serveftp.com :lol:
