Unplug the power cord from the computer, unscrew the screws holding the side panel onto the computer and remove the side panel if the power light originally turned on. Check the wires leading from the "Power" button to the motherboard inside the computer to see if the connections have come loose. If so, plug the connection back into the plug at either end.
