I'm currently having a problem with my Vostro 3460. Once in a while, when I plug in the AC Adapter to my laptop, it'll make 2 beeps sound and show an error about battery is unrecognized, the battery light in the front panel will flash between amber and white. I have tried to reseat the battery several times but it's not working. Below are some pictures I took when this happened:
