I have a Dell Inspirion 600m and when I turn on the computer all the status lights (power, HDD etc.) blink red while the computer is on. When I pull the power cord out the computer goes into hibernate automatically. I have no settings telling the computer to do this. When I pull out the battery and hit the button to see how much charge is left all the lights blink green three times and then stop. Does anyone know if this is an indication the battery is dead? Is this a symptom of something else?
