Make confident that the power wire to the monitor is firmly plugged into the rear of the monitor. Trace the power cable from the monitor back to the receptacle and be sure that it is connected to a live outlet. * Analyze to see if the monitor video cord is secured to the rear of the monitor and that the other end is solidly coupled to the video port on the personal computer. * Still no luck? Try unplugging and re-plugging all cables. take off all wires from the laptop including power, monitor, mouse, keyboard, printer, network, and any other attached devices.
