Initially, let's try a hard reset by removing the battery. Let it be without batteries for a couple of minutes to about an hour. Thereafter re-insert battery and try again. Additionally, pls verify that the battery is fully charged
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced. 2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop. 3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work. 4. The power button could be bad. 5. The motherboard could be defective & needs to be replaced.
Does your laptop have its lights on the keyboard even if your screen is black? If it is , try to remove the cables and battery of the laptop. Press and hold the power button for 8 seconds. Then reinsert the cables and battery on the laptop. Turn on the laptop, and if there is no light on screen & keyboard, it means that the power supply or the motherboard has trouble. That is the time to contact Dell support for possible repair or replacement. Otherwise if the keyboard has lights but the screen is still black, that would be a video card problem since the LCD screen is not a separate entity. Just make sure if it has the power button on the screen, it is turned on. That instance would need a video card replacement...

i used to frequently take out the battery on my machine and put it back in over and over again until one time it sparked and made an audible pop. now it only works on ac power. some thing inside your laptop may be fried, or there may be an illegal contact somewhere either inside your laptop or inside the battery. or there may be something on the contacts that connect the battery to the laptop.
