These are the significant factors that contribute to power consumption the most. But a laptop with 17-inch screen size or above can consume up to 100 Watts per hour or more. A 15.6-inch laptop will consume 60-70 Watts of power in an hour. The larger the screen size, the more power it needs. The size of your laptop screen also contributes as one of the factors to its power consumption. Whereas a high-grade CPU such as Intel i7 or Intel i9 will perform way better while consuming less power. A low-grade CPU uses more power to provide a laptop with high-quality performance. But when it comes to running a task associated with heavy functions, a lower-grade CPU will consume much more energy. The type of CPU used to run all these functions plays a massive role in power consumption.įor finishing simple tasks, both high-grade and low-grade CPUs will end up consuming almost the same energy. The operating system and all the other applications used in a laptop are run by the central processing unit (CPU). The one with a higher adapter wattage will consume more power than those with a lower wattage. The number denotes how much power it will consume in an hour when in use. The majority of laptops (15.6 inches) available in the market are supplied with a 60 W charging adapter, while 17-inch ones are supplied with a 90 W charging adapter. The adapter is used as a power supply for your laptop connected to the central system.įor larger laptops, the adapter used needs to be more powerful. A laptop being charged will also consume more power. Several laboratory tests suggest when a laptop is consuming power at a rate of more than 100 Watts per hour, it gets hot and needs a cooling pad. They can consume up to 160-185 Watts per hour. However, laptops used for gaming or other high-end laptops consume way more power than that. Laptops used for basic, everyday work use about 60 Watts per hour. Laptops used for different purposes will consume power differently. The kind of laptop that you use plays a huge role in power consumption. Touchpad Type of Laptops and Their Purposes.Here are some factors that are involved in the power consumption of a laptop: As we move forward with time, companies are producing more energy-efficient laptops. They tend to provide high-quality performance making the least possible power consumption.īut there are significant consumer components like the display or the processor that consume more power for optimum performance. The components that build up a laptop are made to be energy-efficient. Does the laptop wattage differ for different brands (such as Acer, Dell, ASUS, HP, etc.)?
