Dell designed the Latitude D610 laptop to use the Intel Pentium M processor and the Intel 915GM chip set. The system, which supports the Microsoft XP operating system, was introduced to the market in 2004. To clear the complementary metal oxide semiconductor (CMOS), follow a two-step process, which involves removal of the coin-cell battery and the clearing the Electrically Erasable Programmable Read-Only Memory (EEPROM) chip. The Dell Latitude series of computers uses EEPROM chips to hold CMOS data as an additional level of security. Unlike in a personal computer, the removal of the coin-cell battery does not clear the EEPROM chip. The procedure allows the computer owner to reset CMOS settings without dismantling the laptop.

Shut down the operating system. Save all data, close all open files and exit any open programs, if possible.
Click the "Start" button. Click "Turn Off." The computer will turn off after the operating system has completed the shutdown process. Alternatively, if you are unable to access the operating system, hold down the power button until the laptop has shut down.
Remove all external devices attached to the computer. Ensure all media, video and smart cards have been removed.
Do not remove the battery pack. The computer must have an electrical current to complete the process.
Before Resetting the CMOS Chip
Turn the computer over and remove the screw on the modem/coin-cell battery cover. The cover is located just below the audio jacks.
Use your finger or plastic scribe tool to lift the cover. An indentation in the cover allows for easy removal. Remove the coin-cell battery from its plastic casing. Detach the battery from its cable. Touch an unpainted medal portion of the computer to protect against electrostatic discharge before touching the coin-cell battery.
Place the laptop on its side with the cover slightly open to access both the modem/coin-cell container and the power button located on the top section of the keyboard. Check whether the battery pack and AC adaptor are connected to the laptop. Ensure the AC adaptor is connected to a working wall outlet.
Clear the CMOS settings on the EEPROM by placing a flathead screwdriver on the three silver pins on the left side of the chip while holding down the power button on the laptop. The laptop should power on and load the XP logo screen, bypassing the "Password Request" page.
Power down the laptop. Replace the coin-cell battery casing, battery and cover. Restart the computer, allowing the laptop to fully load the operating system and drivers associated with all peripheral devices.
