Section 1.3 provides you a way to clear Password. However, I am not sure it will work for your case or not. 

1.3 Clearing a Password 
If the notebook you are servicing has an unknown password, 
follow these steps to clear the password. These steps also 
clear CMOS: 
1. Prepare the notebook for disassembly (refer to Chapter 5, in 
section “Preparing the Notebook for Disassemblyâ€\302\235 for more 
2. Remove the real time clock (RTC) battery (refer to Chapter 5, 
in section “ RTC Batteryâ€\302\235). 
3. Wait approximately five minutes. 
4. Replace the RTC battery and reassemble the notebook. 
5. Connect AC power to the notebook. Do not reinsert any 
battery packs at this time. 
6. Turn on the notebook. 
All passwords and all CMOS settings are cleared.
