Question about Dell Inspiron 4000 Notebook
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. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced

Take an ink pen and push the tip inside the jack and see if
the little pin wiggles, if so the jack is bad. You'll have to take the laptop
apart to fix it. Most times it is soldered onto the motherboard, so you
will have to desolder the old and solder a new one.
