In most cases you have to contact customer support and give them serial number of your laptop so they can give you UNIVERSAL BIOS password for your machine.

Will post other methods later.

    If you have access to BIOS , you can turn it off from security settings, or try to ask kids what password they put in. Otherwise try this.

    1) Turn off computer
    2) Disconnect AC adapter
    3) Remove battery pack, and remove the laptops keyboard
    4) Disconnect RTC (Real Time Clock) battery (located underneath the keyboard, the red/white wire)
    5) Leave off for fifteen minutes
    6) Reconnect the RTC battery and reassemble the laptop
    8) Turn on the computer and enter the BIOS by pressing F10
    9) Set the new BIOS password and save all settings.
    10) Turn off the laptop and reinsert the battery

    To be short
    1) disconnect all power sources ( both AC and battery)
    2) remove remove RTC battery (cmos battery) for 15-20 minutes
    3) place them back and passwords should be gone.

Were can I find the RCT battery in a compaq 6720s? Actualy I have forgotten my power on password. so i want to remove the RCT battery but i can't find it. can you help me please?

Laptops dont store the BIOS password like desktops meaning that even if you find the Battery the password wont be deleted since its stored on a eeprom.
best way to go is to go to compaq they will help you if you have proof of purchase

Did not put a power on password but my systems asks for one.

The backdoor password for Compaq computers is "Compaq". Try entering that and it should work.

I got my compaq desktop pc locked

Try starting your PC in Safe Mode.

To get into the Windows 2000 / XP Safe mode, as the computer is booting press and hold your "F8 Key" which should bring up the "Windows Advanced Options Menu" Use your arrow keys to move to "Safe Mode" and press your Enter key.

Safe mode takes a while to load but once it is loaded, I think you can use control panel to get to "add/remove programs" - then hopefully you can uninstall "screen on password"
