If servicing a notebook with an unknown password, follow these steps to clear the password. (These steps also clear CMOS.)
Prepare the notebook for disassembly.
Remove the real time clock (RTC) battery.
Wait approximately five minutes.
Replace the RTC battery and reassemble the notebook.
Connect AC power to the notebook. Do not reinsert any battery packs at this time.
Turn on the notebook.
All passwords and all CMOS settings have been cleared.
Notice that this is a different model but it just may work for you. Also, notice that all of your CMOS settings will be cleared. You will have to go back and reset all of your specific settings if any apply.
