SOURCE: lost system password

Only way to remove a BIOS password on any computer is to remove all power sources from the motherboard so its memory can be cleared.

First, remove the main battery from the laptop. Then you must locate and find the little coin cell battery (It looks like a watch battery) on the laptop and remove it for about a minute or so. Then you can replace them in the opposite order.

Your coin cell battery is in a bay on the bottom of your computer. Enjoy!
1. Before removing the coin battery:

2. Locate the memory module cover on the bottom of the system.

4. Lift and remove the cover from the system.

5. Locate the coin battery.

6. Use a fingernail (or small flathead screwdriver, if necessary) to release the battery ZIF connector.

8. Reverse the previous steps to replace the coin battery.

SOURCE: NEED ADMINISTRATOR PASSWORD FOR DELL LATITUDE C600/C500

If this password is for Windows, then you will need to contact who set the password originally. Optionally you may use tools online to reset the password. This would require purchasing a utility like SpotMau.

If this password is for the computer it self, before booting to the OS, you have to remove the BIOS battery to clear the BIOS password.

Removing the screws on the bottom of the laptop, the bezel at the top and the keyboard, check the bottom and top of the system board, you should see a flat-cell battery or a plastic coated series of batteries with a cable going to the system board.

Good luck
