HP Pavilion dv7-3057nr Notebook AC Adapter Charger 19V 4.74A 90W high quality,1-year warranty, 30 days free return.
I have been dealing with my laptop being in almost a constant state of "Low Battery" alerts for several months. Many times, even when the charger light was on the battery was not charging. I finally got fed up and searched for and found "ChargerBuy.com". I entered the information from the back of my"so-called "charger and the correct replacement immediately appeared. The price was very reasonable so I purchased it and it arrived in a couple days (I used the cheapest shipping method). My laptop is now keeping a 100% charge! THANK YOU!
