As a rule of thumb, a typical 15-inch laptop consumes roughly 60 watts of electricity every hour. However, this would necessitate further expenditures. You may not know the many elements that influence your energy use.
Charging, screen brightness, programme operation, graphics card use, and other factors affect how much power is consumed. In this article, we will also talk about How to Reduce Laptop Power Consumption.
How Many Watts to Run a Laptop?
The 65W laptop power supply is the most prevalent. Laptop wattage ranges from 30W to 200W, according to a study of 144 of the most popular laptops on the market.
There are, however, a few exceptions. Over-200-watt gaming laptops are becoming increasingly frequent (more on this below). The wattage of some of the most admired laptops may be found in the table below.
| Laptop | wattage |
| Lenovo Yoga | 65W |
| Dell Inspiron 15 | 90W |
| Dell Inspiron 14 | 65W |
| MacBook Pro 16 | 96W or 140, depending upon the spec |
| MacBook pro 14 | 67W |
| MacBook Pro 13 | 61W |
| MacBook Air | 30W |
| Lenovo Chromebook 3 | 45W |
| Lenovo Ideapad 3 | 65W |
How many watts to charge a laptop?
Laptops use far less power than desktop PCs and external monitors, which is why laptops are becoming increasingly popular. Laptops are typically charged to 100% once a day on average. The power required to trust a computer varies from laptop to laptop, but the typical range is between 20 and 50 watts.
However, not all this power goes towards charging your laptop’s battery; on average, over 30% of this energy is lost as heat emission and excessive radiation during the charging process. The power delivered to your laptop is only about 70% of what it needs to be charged.
Always remember that the quality of your battery significantly impacts how quickly your device’s battery recharges. Your laptop’s ability to charge is affected by the electricity it consumes. Setting time is inversely proportional to how much power your computer consumes when charging.
For example, when using a large laptop, it will likely consume more power in standby modes than a smaller laptop, such as a notebook or a tablet, when used commonly. We have another awesome article on the same topic that is How Many Watt does a Laptop use when Charging?
How Many Watts Does Gaming Laptop Use?
All gaming laptop features are compelling and require a specific set of parts. That being said, there are a few others that deserve special mention.
Running high-end games is understandable to gamers because you’ve played them yourself. Because of its class, the laptop must be among the best available. Because they’re so loaded, gaming laptops are also getting heavier.

Desktop Computers Require More Power Than Laptop?
Laptops require less power than desktop computers because of their more efficient energy use. Due to the significant force necessary for desktop computers to carry out their functions, these devices are permanently connected to their respective power supplies.
There are laptops out there that consume a lot of power. These PCs might use more electricity than those that consume less energy overall. On the other hand, as a rule of thumb, desktop computers will consume more power than laptops.
In general, desktop computers require about 300 watts per hour. Connecting another monitor to it or having a significantly larger screen can contribute more than 50 watts of power consumption. On the other hand, typical laptops might require sixty watts an hour.
6 Ways to Reduce Laptop Power Consumption
These ten simple suggestions will help you save money on your laptop’s electricity bill. Several of these also help conserve battery life when the computer isn’t plugged in.
1- Make Sleep Adjustments:
You can save excellent margin money on your electricity bill by turning your laptop into sleep mode sooner when you are not using it. The ENERGY STAR estimates an annual savings of $15 per computer. If you work from home or use your smartphone for extended periods, you may expect to save at least this amount.
Laptops ship with a sleep mode duration ranging from four to thirty minutes. Over 1,000 laptops have been studied, and the most common sleep mode duration is 10 minutes, with an average sleep mode duration of 18 minutes.
2- Remember Display Sleep Mode:
Display sleep mode, distinct from the primary sleep mode feature, is found on many laptops. If you want to save power, but the screen to sleep, don’t worry about your apps running in the background. Think about turning off your display when you’re not using it rather than turning it off.
More than 1,000 laptops have been analysed, and the default time for display sleep mode spans from 4 to 15 minutes when shipped, with 10 minutes being the most common and 9.5 minutes being the average.
3- Power-saving Mode Is Activated:
Most laptops have a power-saving mode that may be active by pressing the power button. This mode reduces the performance of some laptop functionalities to conserve electricity. Check out this mode, as most functions will still work fine.
4- Dim the Screen’s Illumination:
The brightness of your laptop’s display considerably impacts the amount of electricity it consumes. A lower level of intelligence means reduced power use.
5- Reduce the Temperature:
Laptop fans, by their very nature, use electricity. When there is less airflow around the laptop, such as when it is sat on and surrounded by bedding, they are needed more frequently. Consider where you set the gadget when using it, and ensure that the heat dissipation is adequate. As a result, the laptop will use less electricity to stay calm.
6- Unplug and Turn Off the Power:
Even when unplugged, most laptops use power even after being shut off. A computer in Off mode can use more electricity daily than a laptop in Sleep mode, even though Off mode uses less electricity. Remember to disconnect your devices to conserve electricity.
