I got a Dell Vostro 1500. The problem i had is that when i was using office suddenly the power turned off and the monitor is totally black. Looks like a total power blackout. I checked everything, the power led, and the light on the button but everything is not working. Even the battery that suppose to backup but still seems its totally not working too. And looks like its totallt drained. I tried to push the button to power it on, but its no longer working. I removed the adapter connection from the laptop and from the electric socket on the wall of the house. I plugged it again and the power led on the adapter is working. But when i connect the adapter to the laptop, the power led on the adapter was gone. I tried this several times but still the same thing happen. Even the battery is attached to the laptop the same thing happen. I dont know what happen but i think there is a board or power problem. Is my laptop is dead?
