How many watts does a laptop consume

Laptops are a basic need of every household and office these days. With a good quality laptop, you can get things done with ease, whether for entertainment or work-related needs. No matter how tech savvy you are, there are certain things which never seem to concern the users. One of these things is the power consumption of your laptop.  

No one has ever asked how many watts my laptop consumes, because it does not matter that much. But if you are a curious person and need to know the watts consumption of your laptop, then you don’t have to worry. We are going to be talking about everything there is to know about the power consumption of a laptop. So let us not waste any more time and get right to it.  

How many Watts my laptop consumes? 

The power consumption of a laptop depends on many factors. The different laptops or setups provide different performance, which means that the power consumption will also vary. But if we put it in very simple words, then a regular 15 inches laptop will consume 60 watts while a 17 inches laptop will consume something around 90 watts. If you are using an Apple MacBook, then a 15 inches MacBook will consume 87 Watts per hour.  

What about Gaming laptops? 

The power consumption of gaming laptops is much different whether you are using new or refurbished laptops for this purpose. You need a good amount of power to run all the AAA games with ease and precisions. A gaming laptop is equipped with a powerful GPU, cooling technology, and the battery which can keep on going. All of these components are really high energy consuming. You might have seen that the charger of your gaming laptop has a power of 180W, so it means it will consume 180 watts per hour.  

Factors which affect Power Consumption 

As we mentioned earlier, there are many factors which affect the power consumption of your laptop. So, the power consumption can vary from laptop to laptop. Below mentioned are some of the factors which affect the power consumption of laptops.  


The first factor is obviously the type of laptop which you are using. For example, if you are using a laptop which is made for work or casual computing then it will consume less power. A normal 15-inch laptop will consume 60W per hour but if you are using a high-end gaming laptop, then it will consume more power that is for sure. So, the power consumption depends on the type of laptop which you are using and for what purpose you use it.  


Next factor is CPU, but it is not simple as it may seem. If you are using a low performance or low-grade CPU, then it will use more power than what would be used if you are using an Intel Core i7 or i9 processor. The reason behind this is that a low-grade CPU or processor will require more power to work in a decent way. Whereas on the other hand a powerful processor will give you good performance while consuming less power. So, if you want the power consumption to be as low as possible then consider going for a powerful CPU.  

Graphics Card 

It is pretty simple, that the higher your GPU is the more amount of power it will consume to provide great graphics quality. The high-end graphics cards like RTX 2080 or any other will use up a good amount of power so the gaming experience can go as smooth as possible. If you are using a laptop with very high GPU then it is obvious that it will also have a mighty CPU, along with the best display and long-life battery, all of these factors will ultimately use a high level of power.  


Adapters are something which play a major role when it comes to the power consumption, but most people don’t know about it. You can just see your charging adapter and find out how much watts it will consume. If you are using a 15.6 inches laptop then the charging adapter which came with it will be a 60W charging adapter. If you are using a 17 inches laptop then it will have a 90W adapter. These watts written on the adapters simply mean the power it will be consuming when in use.  

How to consume less power? 

If you want to lower the power consumption of your laptops, then it can be done. There are some ways or methods which you can adapt to make sure that your laptops are not using unnecessary amount of power.  

  • The first thing to keep in mind is to always remove the charging plug from your laptop when it is charged completely. Even if the laptop is fully charged but the charger is plugged in, it will keep consuming battery and this is not all, it can affect the health of your battery as well.  
  • Never let the battery of your laptop drop below 10 % and wait for it to switch off before you charge it. It will take more power to charge a battery which is completely drained out. So, make sure to charge the laptop before it reaches 0% and also never overcharge your laptop, because both these things will degrade the performance of the battery and then they will require more power to be charged.  
  • Keep the temperature of your laptop cool because it can also affect the power consumption. Make sure your laptop is cooled down before you restart your work. It is also recommended that you get a cooling pad for your laptop as it will make the heat dissipation process much faster and accurate.  
  • Keep in mind to upgrade your laptop’s processor and other hardware, which will remove unnecessary pressure from your laptop and consume less power. In addition to that you should always use the original charger which came with your laptop.
