Hi:

My dell inspiron 5160 laptop will not start when turned on. With the battery as I press the on-button, I only see a green ac-power led light come on and at the same time I can hear the fan on. Suddenly the laptop turns off just like that. When I take the battery out and try to turn the laptop on with the ac power adapter, nothing happens. Also with the ac-adapter plugged into ac and battery it turns on for a couple of seconds just like with the battery alone. please help
