Use this guide to replace the motherboard in the Dell Venue Pro.
A damaged or malfunctioning charging port is a common reason for motherboard replacement, since the charging port is integrated into the main logic board.
This is an advanced repair that requires removing several internal components. Before beginning, power off your device and remove the back cover and battery.

-
Use your finger to lift the battery using the notch in the upper left corner of the compartment.

-
-
Insert a plastic opening tool into the seam between the midframe and the phone body.
-
Gently twist the tool to release the clips around the edges.
-
Once all clips have disengaged, lift the midframe away from the phone and set it aside.

With the midframe removed, the motherboard should now be fully visible.
