Recently it seems my laptop's charger port has completely stopped working. It suddenly stopped even holding the charger and won't charge at all even if I hold the charger. I've tried multiple chargers on it but it's the same thing with all of them even though they work fine in a friend's laptop (who has the same one). I went to the repair link on the main site but since I'm a month past when my warranty ran out it tells me to go back. Who do I contact to go about getting this repaired and does anyone have an estimate on how much it will cost?
