Hey Guys I have a problem with my Laptop. HP Pavilion zv5120us Notebook PC. It cut off one night when I was asleep. I'm assuming maybe the battery died. The Power Chord was pluged into so I dunno. Now it won't turn on, but when I have just the battery in and I hit the power button. If you listen closley you can hear something inside the Laptop Turn on. Not sure what it is, maybe HD fan? Now when I plug the Power Chord into the Laptop the noise Stops. And when I unplug it, the noise starts up again. Also when I take the battery out the noise stops. And I can put the battery back in and the noise doesn't come on until I hit the power button again. Is there Something Wrong with my Power Jack? Is my battery just not accepting a charge? I don't really want to go spend 150 dollars on a new battery. Anyone have an idea of whats wrong? Thanks in Advance.
