Hp elitebook 840 g3

My hp elitebook 840 g3 core i5 is not displaying anything. After pressing the power button, the keyboard lights flashes for a few seconds, and then only the power button and network button light up, but the screen remains blank. The device is charging and the fan is running fast but the display is blank.
