Laptop BIOS Passwords

Courtesy of the stellar HP/Compaq laptops crew, here is a step-by-step procedure for overcoming BIOS passwords in certain HP laptops (nc series). All steps must be done in this exact sequence.


 * 1) Unplug AC adaptor.  Take out main battery.
 * 2) Remove or unplug CMOS battery.
 * 3) Plug in AC adaptor (both batteries are still removed).  Computer should boot automatically, if not use power button.
 * 4) Machine will boot and show "162 - error msg 'systems options not set'"  Use F1 to save settings.
 * 5) Shut down computer and disconnect AC adaptor.
 * 6) Reconnect CMOS battery.
 * 7) Install battery pack.
 * 8) Restart computer.  All settings are back to factory standards, so update BIOS settings as necessary.
