My inspiron 1525 was smoking out of the vent, so I took out the heating and fan part to clean it. When I put it back in, my computer wouldn't start! The little blue lights come on, and the green lights flicker, but the screen never turns on, and the power light turns off after a moment. I have absolutely no idea what to do!
You need to check all the internal connections if are properly connected also the lcd cable,be sure the cable is not twisted or stucked while closing the cover as if this happens you will get no display,
