nx6125 POWER-ON PASSWORD problem

I recently set my POWER-ON PASSWORD in the BIOS on a nx6125. Later when I powered-up on battery, I got the blue BIOS message "POWER-ON PASSWORD " followed by a graphic of a locked door-key.There was no prompt for a password. I tried several times to type in my "well remembered " password with no success. I was totally locked-out of my notebook. Finally, the battery ran out.

Later when putting the unit on AC power to recharge the battery, I decided to remove the Primary battery and try again. When I did this, I booted normally right into windows. There was NO blue-BIOS message box with: POWER-ON PASSWORD and (graphic key) message. I re-started and pressed F10 with the intent of entering the BIOS and removing the suspicious POWER-ON PASSWORD, to find there no longer was a POWER-ON PASSWORD. Apparently the POWER-ON PASSWORD had been reset as the BIOS asked me for a "New" password. I did not key any new password. Then I shut down the unit, removed the AC power cord, and tried to power-on with battery only, and it powered up normally without any POWER-ON PASSWORD message, booting straight into Windows.

Once I powered on with AC, the POWER-ON password was reset. I don't know if this is what is supposed to happen or if there is a bug in the BIOS which "should have" allowed for the password to be entered when using only the battery. According to " HP Compaq Business Notebook nc6000 Series - Power-on Passwords" document, this should work on battery or AC and does not appear to be working properly.

I would like to use a POWER-ON PASSWORD but don't feel confident it works as it is supposed to. Any constructive feedback is greatly appreciated.

Thanks!

 

How old is your notebook? It sounds like the CMOS battery is completely drained and did not hold the setting. To reset the BIOS in desktop machine, I simply remove the button battery and wait for a while (or short the connections).
