The only way that you can reset a CMOS password is to remove the CMOS battery on the mother board, or toggle a jumper switch (instruction usually comes with the user manual, please check). If you can do either, then password should be reset.

Which operating system ?
The Compaq Presario CMOS password is an administrative security measure built into the firmware of a Compaq computer.

This password is stored in the motherboard's BIOS (Basic Input Output System) and provides for hardware-level security.

This password may be accidentally set or forgotten over time and must be reset in order to boot the computing system.

Disconnect the Compaq computer from any electrical sources and remove the side access panel from its case.

This may require the removal of one or more thumbscrews on the rear of the computer case.


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules

Locate the CMOS battery.

This battery is a round button-type battery located in the bottom-right corner of the Compaq Presario motherboard.

Grip the battery by its edges and pull it straight away from the motherboard to remove it.


Press and hold the power button on the case for ten seconds to remove any remaining electrical current from the computer.

This removes the CMOS settings and returns it to the default state of having no password set.

Replace the CMOS battery.


Replace the computer's side access panel and re-establish any previously severed electrical connections.

How to reset hp elitebook 8460p bios password?


Generally, there are two ways to reset forgotten HP BIOS password. One is forcing BIOS/CMOS to reset itself to its stored defaults by removing all power to it. The other is to use a program to either locate or identify the password and reveal it to you or erasing the password entirely.
And the most easiest and convenient method for erasing dynamic BIOS/CMOS settings is to remove battery directly from the motherboard. It applies to most motherboards besides HP Elitebook BIOS. At this moment, HP Elitebook based on UEFI Bios provides a tool to reset BIOS password specially - HP SpareKey.
How to reset BIOS password with SpareKey?
1. Before forgot BIOS password, you have set answers to three predetermined personal identification questions.
Write down the answers to these questions and put them in a safe place, away from the computer, so that you can always access them.
2. When you cannot remember the password to access the BIOS on your computer, turn on the computer and immediately press the ESC key to display the Startup Menu. And then press the F7 key.
3. HP SpareKey wizard pops up and prompts you for the answers to the three personal identification questions. If you successfully answer the questions, you are granted access and you can reset the password.
If you do not answer the questions correctly in the three attempts, you will be locked out of your computer. And then you must contact HP for assistance.

Note: HP SpareKey cannot help you recover a Windows 7 or Vista administrator account password. It is intended solely to recover system-level passwords.
