The model number should either N214 or PEW91. Well when I took the computer apart, the pin inside the charging port would come loose. So I secured that in place, but no matter what it will not charge. I was going to take it to my friend's if he was allowed out, as he has other Gateway chargers. Also, when we were able to get it to charge, we would have to put the charger cord in an awkward position such as the end facing up and the cord running under it.
