This is the table that shows the lenovo/hp/apple/dell/acer and other leading laptop brands power rating. The power rating terminology used by brands. In other words, we can say that power rating by brands simply means electricity consumption by a laptop.
Furthermore, you do not have to be concerned about the power consumption shown in the listing. These figures are the maximum power consumption of laptops from different brands.
It does not mean that you will reach this level of consumption every time you use your laptop. The actual consumption is very low. Though some brands have high-performing laptops, which consume more energy.
So, it is clear that the actual energy consumption is lower than the power ratings provided by the brands. Lenovo is the brand that uses a small amount of energy.
Analyzing different leading models from different brands, we have reached a conclusion that a laptop needs the following watts of power per hour in different modes.
- A laptop uses 0.34 watts if it is turned off.
- The consumption increases in the sleeping mode, which 0.78 matts
- Idle mode consumes more energy if it is for a shorter period. During long idle periods, the device consumes 2.45 watts. The device consumes 5.91 watts if idle for a shorter period of time.
As we have mentioned above, the common power rating provided by brands is 65W. But most laptops do not use 65W to perform their duty. Most devices use half the power rating provided by the brands. Based on this, we can say that in active mode, a laptop’s energy consumption will be 32.5 watts per hour.
Here is another table that shows the power usage of a laptop in watt-hours.
Mode | Watt hours consumed per day | Watts hours used per month | Watts hours used per year |
---|---|---|---|
Active mode | 50.34Wh | 1,531.1Wh | 1,8373.2Wh |
Sleep mode | 0.23Wh | 7.1Wh | 85.2Wh |
Off mode | 4.88Wh | 148.4Wh | 1,780.4Wh |
Total | 55.45Wh | 1,686.6Wh | 20,238.8Wh |
Off-mode energy consumption in terms of watts is negligible. But in watt-hour measurement, off mode consumes more energy than sleeping mode. The reason is that a laptop remains off for several hours, which increases the device’s energy consumption.
Watt Hours Consumption of a Laptop Daily
The power needed for a laptop per day varies from 6.3-watt hours to 230-watt hours. The average consumption of a laptop is 55.45 watt-hours. But the most common is 47.12-watt hours per day.
However, there will be extreme conditions during usage. However, these results are based on the typical use of current laptops.
The average laptop consumes 1,686.6 watt-hours of electricity each month, with 1,433.33 watt hours being the most common. The monthly energy consumption of laptops ranges from 191.67 watts to 7,025 watts.
In terms of annual power consumption, laptops consume more watts.
An average laptop consumes 20,238.8 watts a year, but the most common is 17,200 watts. The average laptop uses 2,300 to 84,300 watt hours per year. So, calculating laptop watts per hour is not an issue at all.
Gaming Laptop Wattage or Watts For Laptop
Watts for gaming laptops is more than typical laptops. In short, the increase in power consumption of a gaming laptop is 2-5 times more than a non-gaming laptop.
The wattage on gaming laptops ranges from 30W to 320W. But one thing to keep in mind is that the usage may sometimes pass the average limit. In non-gaming mode, the consumption drops down to normal.
The reason behind the increase in energy consumption is heavy-weight specs introduced. Gaming laptops are usually packed with powerful specs that need a lot of power supply to function properly.
The laptops equipped with Total Graphics Power (TGP) are energy killers. The best example is the ASUS ROG gaming series. The series ranges from 35W to 150W; the most common range is 115W. This shows how much energy is consumed by a gaming laptop.
You can imagine that the NVIDIA GeForce RTX 3080 energy is 320W alone. And there are plenty of other heavy specs to perform the heavy duty. Finding that How many watts does a gaming pc or laptop use will not be an issue for you.
You’re billed based on KWh, so we have to calculate the kWh. Here is the table that shows Watts For Laptop that you consume daily, monthly, and annually.
Mode | kWh used per day | kWh used per month | kWh used per year |
Off mode | 0.0049 kWh | 0.1484 kWh | 1.7804 kWh |
Sleep mode | 0.0002 kWh | 0.0071 kWh | 0.0852 kWh |
Active mode | 0.0503 kWh | 1.5311 kWh | 18.3732 kWh |
Total | 0.055 kWh | 1.69 kWh | 20.24 kWh |
Let’s look at some of the main factors that increase the watts for laptop or laptop wattage.
Types Of Laptops Will Increase or Decrease Watts For Laptop
The power consumption of laptops is directly proportional to the type of laptop. The more laptops you own, the more energy you use. For example, a basic or entry-level laptop will consume up to 60 watts per hour. On the other hand, gaming laptops and workstations consume a lot of power. It may use up to 100 watts per hour.
CPU or Processor
It is quite interesting that high-end processors such as the Core-i7 or i9 consume very little electricity to run the entire system as they are optimized to handle maximum performance with the smallest amount of power. However, using an outdated CPU increases the laptop’s power consumption. A low-grade CPU might increase your expense.
Graphics Card or GPU
The introduction of graphics cards significantly reduced energy consumption. The higher the graphics card, the greater the energy consumption. All high-end laptops come equipped with top-quality graphics cards to meet the requirements of a user.
Gaming laptops and workstations come equipped with RTX 3080, 2080, 2070, or 2060 graphics cards to ensure top-notch performance. Such graphics cards consume a lot of electricity.
Not only is the graphics card known as an energy killer, but it also requires some massive specs to work properly. Those specs or components also use a great deal of energy. These components are screens with better resolution and gigantic batteries.
Adapter Wattage Plays an Important Role In Watts For Laptop
Adaptors on a laptop also play an active role in power consumption. A laptop with a gigantic screen requires an adapter with a 90W rating. Such adapters also require a lot of energy to work properly.
17-inch laptops need a 90W charger. 15-inch laptops will not consume like a low-grade adapter of 60 watts capacity.
Tips To Reduce Watts For Laptop or Laptop Wattage
