If you have a new power adapter (and it is putting out the correct voltage) and you try to turn on the computer and nothing happens, I would suspect that your motherboard has gone bad. The good news is that you can probably find a used one on e-Bay.
Dell portables use a sensing wire in the barrel of the adapter plug to determine the wattage of the ac adapter. If that fine wire in the center of the plug is bent or broken, the system cannot ID the adapter and the battery charger is disabled.
SO, first try a known good AC adapter for a D-Series Dell (You might be able to check with Geek Squad at a local Best Buy if you don'e have access to another ac adapter) If a known good ac adapter works, then replace the ac adapter.
If a known good AC adapter does the same thing then the fault is in the charging circuit of the motherboard and the motherboard will need to be replaced.
sometimes this indicate a fault with memory or the system itsef.Before you begin you will have to remove the battery and the ac adapter.Remove the memory modules .Replace the battery and the ac adapter without the memory.Power it on if it comes on and beep several times then the memory is bad.If not remove the battery and the ac once again.Press and hold the power button for twenty seconds to clear the nonvol memory.Replace the memory the battery and the ac adapter.If still no go remove all the same items along with the hard drive and cd rom,Insert the battery and the ac adapter try again.If you hear a beep this time replace the battery(remember whenever you install to remove power).If nothing works and you none of the desired results you will have to replace the motherboard.
I don't think you are dealing with a short in your system. Your battery is probably dead and/or needs to be charged. See if your new power cord will work and will turn your computer on. Make sure that you have the exact power cord that your specific system calls for, because not all laptop power cords are the same. I mean you can't just use any laptop power cord; it has to be one that is rightly built specifically for your laptop system.
First, you need to check the one that you got for replacement is the correct adapter for your system. If it matches with the old one, make sure that the ac adapter light (LED) is on when you plug it the wall outlet only. When you plug it in the portable and if your ac adapter LED blinks out (turns off) then the motherboard needs to be replaced or else the ac adapter is not working and needs another replacement. Call Dell and have it replaced if you just bought it.
