3 When and How to Replace a Motherboard Battery
The motherboard battery can be replaced as preventive maintenance (it is recommended that this is
done once every 5 years), or it can be done after the depletion is observed.
To replace an X7SBE motherboard battery (that is defective/depleted or as a preventive maintenance),
do the following:
• Unplug the unit from the AC power.
• Place the unit on a EDS safe table where you can perform this operation.
• Open the unit lid by removing the six screws that hold it in place.
• Locate the battery on the motherboard. It is close to the South Bridge (Figure 2).

◦ For a DCP-2000: Remove the Dolphin Tunnel (DPT). The battery is under the Dolphin
Tunnel. To do that, you must remove the two plastic rivets and the screw on the
motherboard that holds it in place.
◦ For a DCP-2K4: Remove the DPT. The battery is under the Dolphin Tunnel. To do that, you
must remove the two plastic rivets, one screw that attaches the DPT to the rear panel, and
the screw on the motherboard that holds it in place.
◦ For a Showvault-3 and ShowVault-4: There is no Dolphin Tunnel, so go to the next step.
• Using a flat thin screwdriver, push the battery socket tab towards the socket margin, until the
battery is released and pushed upwards.
• Pick up the battery by hand. Do not use tweezers.
