A shot pellet that, has an inner core of a material such tungsten carbide, that is coated with a layer of bismuth. The user IHS includes a storage system having a storage device, and a storage repair function that periodically provides a storage device image over the network to the storage IHS using data from the storage device. The source driver and the backlight driver respectively generate data voltages and driving voltages to drive the at least one pixel block and the at least one pixel block according to the average gray level value. Accordingly, cooling effects suitable for the heat dissipation units are generated in order to achieve an optimum heat dissipation effect.
