Notebook section may yield better results for ya
it could be the adapter itself or it could be the battery itself or it could be the port on the laptop itself
if your lucky enough to know someone with the same laptop youd be able to rule some of the things out but besides that idk
altho since you got it from bestbuy it is possible you could bring it there and see if you could get them to let you try another charger for the same model laptop there in the store, if it still dont charge that leaves the battery or the port itself
then if they were also kind enough to let you try a new battery and your old adapter worked you would know its the battery
only other option that i can think of is just buying a brand new charger and battery which i personally wouldnt do right away cause if its the port on the laptop itself then it would just have been a waste of money
