Check too see if the laptop has a charging light, and if so make sure the light shows a charging indicator when plugged in. If it does not, then it could be a faulty charger or a short somewhere on the laptop motherboard. If you charger has a light on it showing its working fine and the laptop has a charge indicator showing that its not charging then it could be a short. If the charger or laptop do not have power indicators then go ahead and leave a comment for me too assist some more.
