Unable to turn on my laptop, able to charge but system not turning on

1) When you push the power button does it light up? If it lights up, does it blink? If it blinks, what colors & what pattern of blinking (i.e. two long blinks, one short blink, one long, then repeat). Dell has diagnostic codes info for your laptop at:

2) Will it power on with the battery removed from the laptop? If yes, the battery may be bad.
