My hp pavillion dv9000t has had problems with the battery since i got it. i have already had to get a battery twice because they no longer last very long, about 2 minutes on battery alone. Now they won't even work when plugged in. My labtop would turn on and get to where it was loading my system tray. Then die but it wouldn't say that it was plugged in or charging. There are 2 notification lights that tell when the battery is charging, neither of them light up any more. My question is when i go to best buy to get another labtop battery from warrenty should i brign my notebook and tell them that the charging system doesn't seem to be working, or will that probably work once i get a new battery.
