The usual 15-inch laptop consumes about 60 watts per hour. However, this is not the precise quantity of energy it would require. The amount of electricity consumed is influenced by various elements that you might not be aware of. Additionally, charging, screen brightness, running applications, and graphics card use are all factors that affect power consumption. For a better understanding of power consumption by laptop, continue reading the article.
Types of laptops
There are three main types of laptops available, which include the following:
- Workstations
- Gaming laptops
- Standard or everyday use laptops
Workstations
Workstations are typically used for high-level business computing and professional work, such as graphic designing, video editing, and other weighty applications.
Gaming laptops
Gaming laptops are designed for those who enjoy playing video games, as they typically have the higher processing power to run the high-definition graphics that today’s modern games require.
Standard or everyday use laptops
Standard or everyday use laptops are similar to workstations in that they can handle a variety of different tasks relatively well. However, standard use laptops typically do not have the processing power of workstations or gaming laptops.
CPU
The essential factor in determining how much electricity a laptop will consume is its CPU. To determine which type of CPU a laptop has, you need to know the brand and model number.
These two pieces of information can usually be found on a laptop’s outer casing, just below the laptop’s screen. Once you have the brand and model number, you can determine which type of CPU it is using an online database such as CPU Monkey or watching an informational video about CPUs.
Graphics card
Another factor in determining how much electricity a laptop will consume is its graphics card. A laptop’s graphics card assists the CPU in processing information and displaying images on the screen. For example, when you open a new document or webpage within your word processing program or browsers such as Microsoft Word or Google Chrome, the CPU will send the information to the graphics card, displaying it on your screen.
Adapter of laptop
The wattage of the adapter is also another factor in determining how much electricity a laptop consumes. The wattage of an adapter determines how fast or slow a laptop charges and operates, so it is essential to choose an adapter with lower wattage when purchasing a new laptop.
However, sometimes you will need to buy an adapter with higher wattage for your laptop’s functions to perform correctly. For example, if you plan to play video games or watch videos on your computer, you may need to get an adapter with more wattage than usual for it to run smoothly and charge faster. As you can see, three main factors determine how much energy a laptop consumes: its type of laptop, its CPU, and its adapter wattage. By knowing these three things, you will purchase an efficient laptop that fits your needs.
How many watts does a laptop use
The number of watts a laptop uses can vary depending on several factors, such as the laptop’s model, age, and usage. On average, a modern laptop typically uses between 30 to 90 watts of power, with most laptops falling within the 45 to the 65-watt range. However, this number can fluctuate depending on the laptop’s screen size, resolution, graphics card, and processor.
Some laptops are also designed to be more energy-efficient, utilizing power-saving modes or features such as automatic brightness adjustment to reduce power consumption. Additionally, the type of tasks being performed on the laptop can also affect power usage, with more intensive applications like gaming or video editing using more power than simple web browsing or document editing. Overall, understanding the wattage usage of your laptop can help you make informed decisions about energy consumption and help you optimize your laptop’s performance and battery life.
How do you calculate how many watts a laptop consumes?
A laptop’s charger power consumption, along with other factors, can be determined approximately. You can use an electricity usage monitor if you want to know how much power your laptop consumes.
Manual Calculation of watts
Taking power used to charge your laptop (Adapter wattage) is easy to estimate the approximate amount of energy your computer consumes. The Acer Predator Laptop has a charging adapter that consumes 180 Watts of power per hour. Aside from this, the CPU and GPU of the machine tend to consume more power.

Power Consumption:
A typical laptop computer draws between 30 and 60 watts. If you have other devices connected to the same AC circuit, be sure to account for their power draw so that you do not overload the circuit.
Power Cost:
Calculating the cost per kWh is reasonably straightforward. Just go to your local electric utility’s website, and they should be able to provide you with this information. Electricity can be expensive in many countries, but hopefully, the next few years will see it get less and less costly as the grid becomes more efficient and we switch over to alternative energy sources such as solar or wind power.
A 14-inch laptop uses how many watts?
According to estimates, 14 to 15-inch laptops consume an average of 60 watts per hour of electricity. Therefore a computer utilizing 60 watts for 6 hours a day when plugged in will cost $0.0648 daily (if you are in New York).
Conclusion
With a regular computer with essential functions or a small notebook, the machine will only use around 60 watts. The power consumption of a gaming laptop can be as high as 100 watts per hour. Modern gaming laptops will consume more power than the average energy unit cost.
FAQs
How many watts does a laptop use?
If you have a desktop, it uses 160W. If you have a 15-inch screen on a notebook, it’s about 200W. 16-inch screen laptops are around 250 watts, and 17-inch screens use up to 300 watts of electricity. The giant 19-inch monitors can suck up more than 450 watts.
A laptop uses about 3 W of electricity when switched off or in sleep mode (it takes around 175 hours for the battery to run down) and about 2-8 W when running on its battery or electrical supply.
How many watts does a laptop charger use?
Most notebook computers require external power supplies (AKA AC adapters) to convert household electric current into low voltage direct current that can operate the computer’s internal components. These can range from 65W for smaller notebooks to 120W for larger laptops with extra power-hungry features such as a bigger screen or dedicated graphics card.
The laptop battery is charged from the AC adapter current. A fully drained battery can be recharged from flat in just over an hour by most modern adapters, reducing to around half that time for Acer Aspire One and Dell Inspiron Mini notebook computers thanks to their power-saving Hyperactive technology.
A 17-inch laptop consumes how much power?
They usually have 90 Watt adapters. This depends on many factors, such as the power of your graphics card, your CPU, etc.
