One of the configuration details that a computer's Complementary Metal Oxide Semiconductor (CMOS) can store is a password that the user enters to prevent unauthorised users from accessing the computer. If the previous owner of a Dell Latitude D610 that you have purchased used this feature, you may find yourself in the unfortunate situation of being unable to use your computer. A battery inside the Latitude D610 that allows the CMOS battery to remain charged when the computer is off can be removed to reset the CMOS memory.

Shut down the Latitude D610 and close the screen. Remove the main battery and the auxiliary or slice battery, if applicable. Disconnect the AC adaptor cable. Turn the computer over and position it so that the audio jacks on the side face you.
Unscrew the Phillips screw for the plastic panel under the audio jacks. The screw is captive and remains inside the panel. Take the panel off of the Latitude D610 and set it aside. Under the panel is a circular battery with a twisted cable leading to the computer motherboard.
Grasp the plastic connector at the end of the twisted battery cable and remove it from the motherboard.
Turn the Latitude D610 over, open the screen and replace the AC adaptor cable. Turn the computer on. The computer displays a message explaining that you need to input the system date and time. This indicates that the CMOS battery has been reset. Turn the computer off.
Reconnect the Latitude D610 CMOS battery cable and replace the cover panel.
