Disconnected the RTC battery will unlock your system. See the steps below.

The more important it is to protect on's data by a DriveLock (which makes the HDD usuable when the password is not available).

Procedure to remove password
(following CPQ MSGs)

1.) Unplug AC, take out the main battery.

2.) Take out /disconnect the RTC (real time clock) battery for app. Half an hour (the period of 5 min as specified in the MSG normally is not long enough).

3.) Plug in the AC adapter (batteries still removed); computer should boot automatically, if not use the power button.

4.) The machine will boot and show the 162-error-msg "system options not set". Use F1 to save the settings.

5.) Shut down the computer and disconnect AC power again.
6.) Re-connect the RTC-battery.
7.) Install the battery pack(s).
8.) Restart the computer.

Warning: All settings are set back to factory standard.
You'll have to enter a correct date/time and change the settings to your needs.

Note: Pls strictly keep to the sequence.
Re-starting with the main battery and or RTC-battery inserted will spoil the job.

Power drain would be a better solution in this case.
