Welcome to the Lenovo Community !


Since the laptop fell from table I would suggest that you check to see that the battery pack is fully connected in its socket to the motherboard.  The fall may have partially dislodged it causing a poor connection.  I would also check to see that the power port wasn't damaged if the adapter was plugged in at the time it fell. 


I assume that warranty is no longer active so I've included a link to your model's Hardware Maintenance Manual that will explain how to access the battery pack, etc.
