I've had my laptop for quite a while, I bought it refurbished from Newegg and a while after having it the charger had some issues, the part that plugs into the laptop was not staying in the laptop and I would have to hold it or tape it on or not move at all, then it started to only want to work oriented in a certain way. So I bought an aftermarket one from a website and now that one is temperamental. Can someone give me reccommendations for what charger to get that will work for my laptop, and will be good quality (I don't want to buy the dirt cheep ones) also could someone tell me where to buy a new battery for the laptop, I found this http://www.newegg.com/Product/Product.aspx?Item=9SIA28Z0YE2780 and this http://www.amazon.com/Asus-G75VW-BBK5-Laptop-Battery-Genuine/dp/B00BD60D8Y what's the difference between the two, is one used or something? Any reply would be appreciated, thanks for taking the time to read this.
