Question about Power Computers & Internet
When you plug the AC adapter into the laptop, there are no lights turning on at all. When you push on the power button, nothing happens. The laptop appears to be completely dead, makes no sounds, no indications of life.
You'll need to replace the coin cell battery on the motherboard to get it to boot again.

SOURCE: Screen went black
Just a thought... There's a "Fn" Key located beside the Start key, when you press this "FN" key + F5, the screen goes black, and if you press again, the screen goes back to normal... Could this be the problem?

Take out the battery completely and only hook up the adaptor and see if it turns on then. If it turns on then your battery is bad. If you try both adaptors and get the same flashing lights then the motherboard is bad.

nope, it is your dc power regulator board. you will note this happens if the battery is in or out of the laptop. that is the key test. some regulators are on the main board and some are seperate for this reason. I think the vostro though is on the main board. A little board re-work will resolve this issue after replacing some components, but this is way beyond a home user's ability.. trust me on this. Sorry for the bad news. Thanks!

Testimonial: "Thanks for your answer. I guess I will check what the repair costs may be, and if too much, just get a new machine."
hopefully you got the right adapter for the machine and if so and still no lights or nothing you can try to hold in the resetr button on the back of the machine and turn on the power at the same time and see what happens if still nothing i would look at getting the machine serviced by a authorized dealer
you may have a bad board or the internal cmos battery is dead or there is a loose connection somewhere ok?
best regards michael

Try removing the battery from the back and then running it directly through the AC adapter. Sometimes the battery and AC adapter have conflicts and it can cause a laptop to become inoperable.
If this doesn't fix the problem in any way, I would recommend trying a new battery or AC adapter.
hope this helps
