Diference between laptop & desktop computer

Most laptop processors are soldered directly in the motherboard, which means they cannot be removed. If there is some error in laptop processor, the entire motherboard needs to be replaced. Laptops processors can be slowed down when they are not running to their full capacity. The processor uses a technique called processor trotling that allows the operating system to put the processor in active sleep mode or shutdown mode. Laptop processors run at reduced clock rate than desktop processors. This helps them to produce less heat when running at full capacity. Laptop processors consume less power which though make them a slow performer but it greatly helps them to save battery life.
