Good evening friends! If the question arises about how much electricity a computer or laptop consumes, then most likely you are thinking about how to save on electricity. In the last article, we looked at how much a typical desktop computer consumes, and it was revealed that its energy consumption depends on what specific tasks it solves. If they are used only for work and surfing the Internet, then the electricity consumption will be less than when running energy-intensive applications such as games.
Today we will look at how much electricity a laptop with average characteristics uses. To find out, you first need to determine what the electricity consumption depends on.
- Power consumption is how much energy the laptop itself consumes.
- Laptop power supply power.
When calculating consumption, it is worth taking into account the second point; it shows how much maximum energy your laptop can take. It is worth noting that the power supplies of all laptops are different; below we will give an example of how you can calculate the energy consumption specifically for your laptop.
So, in order to find out the consumption, let's look at the laptop's power supply; on the sticker there is data on the incoming voltage and current and on the outgoing one.
The input that comes into the power supply from the outlet is designated INPUT, usually written from 110 to 240 volts and the current in amperes. To calculate, we need data at the OUTPUT output, for example 20V == 3.25A. To calculate the energy consumption, we multiply 20V by 3.25A and multiply by an approximate factor of 0.8, since the full power does not consume electricity from the possible one, but only approximately 80%. Then we get
20 * 3.25 * 0.8 = 52 watts - this is the electricity consumption of a laptop in 1 hour
In today's world, sales of laptops or laptops are steadily increasing. There is nothing surprising. For many users, the laptop has become a tool that helps them earn money.
A significant number of students have this modern attribute, which helps them quickly find the necessary information. This miracle of technology is very functional and endowed with high performance.
Today's laptops can easily replace any PC. They are the most convenient means for comfortable access to Internet networks.
Rules for choosing a laptop
When purchasing a laptop, you must clearly understand exactly what actions will be performed on the gadget and for what purposes you need it. This could be stationary work with documentation on the Internet at home or at work. As well as similar work on a business trip or away from home. The laptop can be used as a multimedia center or for playing video games. This business-oriented laptop is perfect. You can choose your assistant based on many other criteria (appearance, technical data, software), but do not forget about one more important indicator: electricity consumption.
Reasons affecting power consumption
The simplest laptop computer, when active, wastes up to 50 W of electrical energy. About 1.5 kW comes out per month. This average shows that this gadget is much more economical than an ordinary light bulb. Basically, the power consumption of a laptop directly depends on its power and components. A particularly powerful video card and processor, as well as a bright screen, will take up a lot of energy. But, do not forget that especially cheap and outdated gadgets are also capable of increased energy waste. The type of laptop model, in turn, affects energy consumption. Thus, compact products with a diagonal of up to 14 inches are more economical than those used for higher loads. There is a direct relationship between software and the amount of energy consumed. But virtually all operating systems can change the power mode (screen brightness, periodically turning off the display during rest). If you don't use your laptop, turn it off. After all, even when turned off, but connected to the network, it can consume up to 5 W/hour.
The influence of battery power on the operating time of the gadget
When purchasing a new assistant, do not forget to pay attention not only to performance and functionality. It is worth paying special attention to the power of the battery. Knowing the parameters of energy consumption (on the power supply) and the battery capacity, you can calculate the approximate time of continuous operation of the laptop.
16 014In our world, laptop sales are increasingly growing. For almost all people who use a laptop, it is a means of earning money. A large number of people use this technological innovation to search for information. In addition to all its other advantages, this miracle of technology is multifunctional and has high performance. But don't forget about how much power your laptop consumes. Nowadays, laptops can outdo any PC. They provide the best access to the World Wide Web.
Basic rules for choosing a laptop
If you want to buy a laptop, you must be aware of the purpose for which you are purchasing it and what it will be useful for. This goal can be either working in a stationary mode with documents at home or at work, or working away. Many users use this technological innovation as a center for multimedia, or for modern games. For businessmen, a laptop will also become an indispensable device.
An electronic device can be selected according to a number of criteria, such as:
- Appearance;
- Manufacturer;
- Technical characteristics (video card or number of cores);
- Software.
How much power does a stupid laptop consume?
Even the simplest device, when turned on, consumes up to 55 W of electricity. The average laptop power consumption per month is about 1.4-1.6 kW. This figure (taken on average) suggests that this device is more economical than even a regular light bulb! The power consumption of a laptop depends on its performance and technical data. More electricity will be spent on a powerful video card, a brand new processor and a bright screen. But don’t think that cheaper and older models will save your energy.
Products whose diagonal does not exceed 14 inches are more economical than models used for heavy loads. There is even some kind of relationship between the technical stuffing and the amount of wasted electricity. But in fact, all operating systems have modes in which you can change the power supply mode (reduce brightness, for example).
If you do not use this gadget, turn it off. Don't forget that the laptop consumes a crazy power of 5 W/hour even when it is turned off but charging.
If you want to buy yourself an electronic assistant, pay attention not only to versatility or performance. Do not ignore the battery power. If you know at least approximately the electricity consumption and battery capacity, you can approximately calculate the operating time of the laptop.
Nowadays, modern technology is coming to the forefront in the world of information technology. Probably, few people have thought about how much electricity a laptop consumes per hour. Due to the increase in tariffs, even rich people are starting to save. So how much electricity does a laptop consume per hour of use? Let's look at this interesting question.
Choosing a laptop
If you are just planning to buy a laptop, then try to pay attention to energy-efficient models. The computer may cost you a little more, but it will save you money on electricity and will pay for itself over time. Remember that different models use electricity differently. To a large extent it depends on the purpose of the laptop. To find out how much electricity a laptop consumes per hour, you need to consider its different types. Unfortunately, we will not be able to get an accurate result.
Electricity costs from running a laptop
- A laptop with average performance. Let's say you bought this laptop for work. You work on it for about 8 hours a day in various office applications, on the Internet, or play simple games. In this case, the laptop will consume approximately 80 watts per hour. In 8 hours, the meter will accumulate about 0.640 kW. For a month this comes out to 19.2 kW. Not bad, right? But this is an average laptop that is simply used for work. Okay, let's move on to the next example.
- Gaming laptop. How much is a laptop with a good processor and gaming video card? A gaming laptop will consume about 190 watts. It is difficult to calculate how much electricity a person will spend using this technology, since different people spend different amounts of time at the computer. But let's say you play it 6 hours a day. In just one day you will spend 1.14 kW, which is about 34.2 kW per month. Quite a big figure.
- Laptop in server mode. There are people who use their computer as a server on which they store photo and video files. Of course, such a laptop is not equipped with high technical characteristics, the only thing is a spacious hard drive (several terabytes). This computer will consume about 30 watts per hour. If it runs 24 hours a day, it will consume about 0.72 kW, which is 21.6 kW per month.
How to find out how much electricity your computer consumes
As we have already found out, it will depend on many details. Completed tasks and computer specifications do not make it possible to accurately determine how much electricity a laptop consumes per hour. If you are buying a new computer, you can determine its power and calculate the approximate costs (this information is indicated on it). But there may be another case, you buy an assembled laptop that does not have any power data. In this case, it will not be possible to find out the approximate costs, unless, of course, it is completely disassembled.
So, let's figure out how to find out how much electricity a laptop consumes? There are two effective ways that we will now consider.
What is the difference between different power consumption modes
Today, modern technologies have made it possible to reduce energy consumption. If you need to go away for a short time, it is not advisable to completely turn off the laptop, but in order to save money, you can switch it to another mode. To do this, you need to run a specific program that will turn off or slow down some components of the device. If you are about to start working on a laptop, the program will automatically start these processes. This created the opportunity to save on the included device.
The laptop does not work, but still consumes electricity, since the program is active and processes can resume at any time as soon as the user indicates this. If your computer is put into sleep mode, it only takes 30 seconds to wake up all components.
The second sleep mode is inactivity or hibernation. This mode is similar to the off state. In this case, energy costs will be minimal. Unfortunately, even if you turn off the device completely, it will waste a small amount of electricity. This is due to networking capabilities.
How much electricity does a laptop consume in sleep mode?
How much electricity does a laptop consume per month?
So how much electricity does a laptop consume? Let's say you have an average laptop that you use for gaming and work. On average, you work on it for 4 hours and play for 3 hours. During operation, electricity costs will be 0.4 kW, for games 0.45 kW and 17 hours of inactivity, which will also require 68-170 W depending on the mode. As a result, monthly electricity costs will be about 30 kW.
How to reduce your laptop's electricity consumption
We have found out how much electricity a laptop consumes per hour and per month; now we need to take care of saving energy. Of course, the main thing is when connected to the network, but there are also certain rules that can help save:
- When buying a laptop, pay attention to energy-efficient models.
- If you feel comfortable, you can reduce the screen brightness.
- Don't spend too much time playing games and turn off your laptop.
- Customize power modes based on your needs and schedule.
Conclusion
Now you can calculate how much electricity your laptop consumes per hour and create a work schedule for yourself that will help you save. Remember that turning off your laptop completely will help with this. If you follow all the tips, you will spend less on electricity.
When buying a laptop, people look at its appearance, technical characteristics, and software. The question of how much electricity a laptop consumes often arises after purchase. In our article we will try to answer it and explain what energy consumption depends on.
Energy consumption factors
Electricity consumption usually depends on the power of its components. A powerful video card, a powerful processor, a large and bright screen - all this will only increase energy consumption. At the same time, you cannot expect energy savings from budget laptops with cheap and outdated processors.
Dependence of energy consumption on tasks
So how much does a laptop consume? Average power consumption is approximately 50W or less. Not very much, right? Of course, this figure also depends on the tasks currently being performed. HD videos, productivity games, and math calculations increase energy consumption.
And of course, how much energy a laptop consumes depends on its model. Small laptops with a diagonal of 11 to 14 inches are usually equipped with mobile processors, which are much more economical in terms of energy consumption. It is not uncommon to have two cards - integrated and discrete. Using the first is more economical, and the second is used only for tasks requiring high load. You also need to remember that even a laptop that is turned off but connected to a power outlet continues to consume electricity. The average consumption in this case is about 5 W per hour.
Software Impact
Separately, it is worth noting the impact of software on energy consumption. Almost all operating systems have the ability to change power modes. Typically, this means changes in screen brightness, periods of the display and hard drive turning off when inactive, and reduced performance.
In our article, we presented the main factors affecting the power consumption of laptops. This information will allow you to use the capabilities of your laptop to the extent that you need and take care of the environmentally friendly operation of your device!
