- Docking problem. If one particular Duo fails to properly interface with a docking device, where other Duos work fine, the one Duo's frame may be bent slightly.
- Battery seating. If the Duo's battery requires frequent reseating, and the power manager requires frequent resets, the frame may not be holding the battery tight against the logic board contacts.
- Duo won't run on battery power. If a logic board replacement temporarily corrects the problem, but needs repeated repair, the magnesium frame may be shorting against the logic board. If the Duo fails to start up on a charged battery, it may be a failed logic board caused by a shorting magnesium frame.
If you encounter any of these conditions, and you feel the problem is intermittent, the problem may be caused by a bent magnesium frame. Consider this component when dispatching. Obviously the magnesium frame won't always need replacement -- but a repeat failure for the same symptom may be a clue.
