my laptop fell on its power inlet with the charger plug in it and I think that something might have been broken. whatever is supposed to be at the back of the inlet, or at the end of the charger is what i think broke. My assumption is that it is the ground pin. how should I go about fixing this, I could return it since it is under warranty but I don't know how long acer would take to get my laptop back to me—my assumption is that it would be a long time. how should i go about fixing this?
