|Your battery may not have been charging after the "Drop". If you have, or can borrow, another Battery, give it a try. Be sure it's fully charged first.|
Try without the Battery installed, just the AC adapter. It's possible you damaged the MotherBoard at the Power Plug connection.
If nothing works take it to a shop for a checkout.
Did you buy the No-Fault insurance policy? Still under Warranty?
There is nothing to learn from someone who already agrees with you.
