These days, laptops and ultrabooks use less power than desktops, which is because laptops are specifically designed to run on batteries and be more energy-efficient. Much of the power consumption of a laptop depends on the size of the screen.

In laptops, you will typically find at least 16-20 watts of power consumption. Charging the laptop will automatically increase the power consumption from 20% to 25%. There are many factors that we are considering when deciding to buy a laptop, such as portability, screen size, storage space, ease of upgrade, and network power consumption.

Most people use desktop, laptop, or ultrabook computers without knowing how much power they consume. If you are looking for the best laptop or desktop with a high-end configuration, you don’t need to think about power consumption when buying a laptop or desktop as it is low-configuration for all kinds of high-end machines. A computer is required. spectrum. Consume more energy.

For example, you have a simple laptop with a low-configuration Intel Atom processor; So it will only consume a few watts. If you have a high-end configuration gaming laptop, it will consume more power than a normal laptop, so you can also say that the power consumption depends entirely on the configuration of the machine.

How many watts does the laptop use?

Let’s say I compare a gaming laptop to a regular laptop. I find a lot of interesting facts about him. A typical laptop typically consumes 55 to 65 watts of power. At the same time, a gaming laptop consumes 160-185 watts of power.

It also depends on the GPU (Graphics Processing Unit). If I talk about the kWh consumption per year of gaming laptops, then the average energy of gaming PCs is about 1450 kWh per year.

Also, taking into account other components of the laptop like screen, RAM, SSD/HDD, WiFi, keyboard, the overall consumption will be higher.

Apple MacBooks: How Many Watts Do They Consume?

A typical 13-inch MacBook Pro consumes 61 watts of power, as you can see from the supplied charger, while a 15-inch MacBook consumes 87 watts per hour, MacBook users know.

Based on the above data, we can easily calculate the cost of electricity that your Apple MacBook can consume each day and week.

Since we already know that a MacBook consumes an average of 61 watts per hour, or 0.061 kWh, and runs for 10 hours a day, it costs about 11 cents a day and a total of $3.3 per month. it is estimated.

How do I check the power consumption of my laptop?

Another way to find out how many watts a laptop uses while charging is through Microsoft hardware or tools. The name of the device is Joule Meter. You do not need to trust the description provided by your CPU. This process is relatively straightforward. All you have to do is connect it to your laptop. You will get instant results in the consumption of your laptop.

Some gaming laptops use 180W per hour and around 135W per hour depending on the model, but the important thing is that gaming laptops use more power than standard laptops.

Screen size

The first major factor in laptop power consumption is the size of the laptop screen. There are different sizes of laptop screens. When it comes to how many watts a laptop uses, you need to consider the size of your laptop’s screen. Laptops with screen sizes of 12-15 inches consume an average of 60 watts, while screens 17 inches or larger use an average of 70 watts or more.

CPU

The power of the laptop used also depends on the CPU of the laptop. If your laptop has a good, powerful CPU, it won’t use as many watts and it will use more power if your laptop has a lower quality CPU in the house.

GPU

The graphics card also has a significant impact on a laptop’s power usage. Most laptops have an integrated graphics card. But if you are a professional gamer and you want your laptop to be perfect for gaming, then you need to use a powerful video card that uses more power.

Adapter

Adapters also have a significant impact on laptop power consumption. Different laptop adapters come in different capacities. Laptops with 15-inch displays typically come with a 65-watt adapter, while laptops with 17-inch displays use a 90-watt adapter. Therefore, the power consumption depends on the size of the laptop adapter.

How can I reduce the power consumption of my laptop?

If, after receiving an answer about how many watts a laptop consumes, the user begins to understand why he received a large amount on the payment receipt, then there is no need to despair. There are many options for saving energy with a demanding appliance.

Some practical guidelines:

The Windows 10 operating system (also in older versions) has a special power-saving mode. To enable it, you need to look for the “Control Panel” in the start menu, where we look for the “Power supply” section. Here, click on “Power Scheme Settings”. Next, you need to specify the soft parameters. Also, if possible, you should reduce the brightness of the screen, turn off Wi-Fi, reduce the working PM of the central processor.

In addition, some of the major components that increase the overall power consumption are the CPU and GPU of the computer.

In most systems, Intel, NVIDIA, and even AMD graphics cards are easy to find.

You can search the official website for the power consumed by these components or open the rear panel to make sure it is 100% safe.

Generally, CPU power consumption ranges from 45W to 50W, while GPU power consumption ranges from 75W to 80W.

The combination of the two usually increases the power consumption of the notebook.

Over 10-15%, this is just an average and can be much higher depending on the type of material used.

Also, talking about the screen brightness, the maximum brightness is 0.5W to 15W per hour.

There are other components like SSD/HDD RAM, but these are some of the components that need attention. please wait.
