not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.
NOTICE: To prevent static damage to components inside your computer, discharge static electricity from your body before you touch any of your
computer's electronic components. You can do so by touching an unpainted metal surface.
NOTICE: Handle components and cards with care. Do not touch the components or contacts on a card. Hold a card by its edges or by its metal
mounting bracket. Hold a component such as a microprocessor by its edges, not by its pins.
NOTICE: To avoid damaging the computer, perform the following steps before you begin working inside the computer.
NOTE: Ensure that the computer is off and not in a power management mode. If you cannot shut down the computer using the computer operating
system, press and hold the power button for 4 seconds.

Coin-Cell Battery
Dell™Latitude™D810ServiceManual

A coin-cell battery maintains computer configuration, date, and time information. The battery can last several years.
The battery may need replacing if you have repeatedly reset the time and date information after turning on the computer or if a message appears that is
similar to one of the following:
Time-of-day not set -please run SETUP programs
or
Invalid configuration information -{
please run SETUP program
or
Strike the F1 key to continue, {
F2 to run the setup utility
To determine whether you need to replace the battery, reenter the time and date in system setup and exit the program to save the information. Turn off your
computer and disconnect it from the electrical outlet for a few hours; then reconnect the computer, turn it on, and enter system setup. If the date and time are
not correct in system setup, replace the battery.
You can operate your computer without a battery; however, without a battery, the configuration information is erased if the computer is turned off or
unplugged from the electrical outlet. In that case, you must enter system setup and reset the configuration options.

To replace the battery:

1. Record all the screens in the system setup program so that you can restore the correct settings in step16.

2. Shut down the computer through the Start menu.

3. Ensure that your computer and attached devices are turned off. If your computer and attached devices did not automatically turn off when you shut
down your computer, turn them off now.

4. Turn off any attached devices and disconnect them from their electrical outlets.

5. Disconnect the computer power cable from the wall outlet, and then press the power button to ground the system board.


6. Turn the computer over and remove the main battery.

7. Open the small access door in the main battery compartment.

8. Locate the coin-cell battery next to the internal card with Bluetooth®wireless technology (optional).

9. Use your fingers or a blunt, nonconducting object such as a plastic screwdriver to remove the battery by carefully prying it out of its socket .

10. Disconnect the coin-cell battery connector.

11. Insert the replacement battery into the socket and snap the battery into place.

12. Connect the coin-cell battery connector to the replacement battery.
CAUTION: Before you begin any of the procedures in this section, follow the safety instructions in your Product Information Guide.
CAUTION: A new battery can explode if it is incorrectly installed. Replace the battery only with the same or equivalent type recommended by the
manufacturer. Discard used batteries according to the manufacturer's instructions.
NOTICE: To disconnect a network cable, first unplug the cable from your computer, and then unplug it from the network wall jack.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before opening the cover.
NOTICE: Before touching anything inside your computer, ground yourself by touching an unpainted metal surface, such as the metal at the back of the
computer. While you work, periodically touch an unpainted metal surface to dissipate any static electricity that could harm internal components.


13. Close the small access door.

14. Insert the main battery and close the battery door.

15. Connect your computer and devices to electrical outlets, and turn them on.

Removing the Microprocessor Module


1. Follow the instructions in "Preparing to Work Inside the Computer."

2. Remove the display assembly.

3. Remove the keyboard.

4. Remove the palm rest.


counterclockwise until it comes to the cam stop.

7. Lift out the microprocessor module.

Installing the Microprocessor Module
CAUTION: Before performing the following procedures, read the safety instructions in your Product Information Guide.
NOTICE: To avoid electrostatic discharge, ground yourself by using a wrist grounding strap or by periodically touching an unpainted metal surface (such
as the back panel) on the computer.
NOTICE: Do not touch the microprocessor die. Press and hold the microprocessor down on the substrate on which the die is mounted while turning the
cam screw to prevent intermittent contact between the cam screw and microprocessor.
NOTICE: To avoid damage to the microprocessor, hold the screwdriver so that it is perpendicular to the microprocessor when turning the cam screw.
NOTICE: To ensure maximum cooling for the microprocessor, do not touch the heat transfer areas on the microprocessor thermal-cooling assembly. The
oils in your skin reduce the heat transfer capability of the thermal pads.
NOTICE: When removing the microprocessor module, pull the module straight up. Be careful not to bend the pins on the microprocessor module.


1. Align the pin-1 corner of the microprocessor module with the pin-1 corner of the ZIF socket, and insert the microprocessor module.
When the microprocessor module is correctly seated, all four corners are aligned at the same height. If one or more corners of the module are higher
than the others, the module is not seated correctly.

2. Tighten the ZIF socket by turning the cam screw clockwise to secure the microprocessor module to the system board.

3. Perform the steps in "Removing the Microprocessor Module" in reverse order, beginning with step5.

4. Update the BIOS using a flash BIOS update program floppy or CD. For instructions on how to flash the BIOS, see "Flashing the BIOS."


NOTICE: Ensure that the cam lock is in the fully open position before seating the microprocessor module. Seating the microprocessor module properly in
the ZIF socket does not require force.
NOTICE: A microprocessor module that is not properly seated can result in an intermittent connection or permanent damage to the microprocessor and
ZIF socket.
NOTE: The pin-1 corner of the microprocessor module has a triangle that aligns with the triangle on the pin-1 corner of the ZIF socket.
NOTICE: You must position the microprocessor module correctly in the ZIF socket to avoid permanent damage to the module and the socket.
