Hey Ageek,

 

Pull out the high powered magnifying glass and light and start looking for a hairline crack on a trace on the motherboard or a solder joint that may have come loose from the impact of being dropped.

 

Sounds as something may have been broken or cracked from the drop. :(

Did the drop happen to end with the adapter connector hitting the floor or got pulled, jammed??  That would indicate the connector on the internal power board is damaged.  Some are mounted to a smaller board that connects to the MOBO, others are mounted directly to the MOBO.  Damage can result in separated connector pins, fractured boards and traces.
