Check the output of the AC adapter. If it is bad then it appears the battery has fully discharged and you need a new AC adapter. If the AC adapter is good, then you have a bigger problem likely the motherboard.

I certainly do not recommend using a Dell adapter. 19V and  4.74 amps (90w) or 18.5v and 6.5 amps (120 Watt) would be the right power. Dell 130w adapter has a very similar plug but is 19.5 volts and would likely damage the laptop if you use it very long.
