Adapter

A laptop adapter has a great influence on laptop wattage consumption. Different laptops come with different adapters capacities. For a 15-inch laptop, it comes with a 65-watt charging adapter while a 17-inch laptop comes with a 90-watt adapter. To know how much watts a laptop charger uses, check your laptop adapter.

CPU

The laptop CPU (central processing unit) is one of the most important components and it is the brain of a machine. With it, your actions including searching, playing games, running apps, etc. can come into true.

It is an important factor for laptop power consumption. If the CPU is powerful and runs properly, the laptop uses less power. But if the CPU is low-quality, the watts your laptop uses are high.

GPU – Graphics Cards

The graphics card also has a great impact on laptop wattage usage. If you are a professional player, your laptop may use a powerful video card to get better visuals. But it consumes more power.

Screen Size

The screen sizes of laptops are different and the larger the screen is, the more battery it uses. The laptops whose sizes range from 12 to 15 inches usually use around 60 watts per hour while the laptops that have a 17-inch or above screen consume 70 watts or higher on average.

Laptop Models

Another factor that decides how many watts a laptop uses is laptop models. Compared with simple laptops, gaming laptops use more power.

And the power usage of gaming laptops depends on the model. A few models can consume more than 100 watts per hour on average.

In conclusion, when asking “how much power does my laptop use”, remember to take these factors into account. You can have a general answer.

Ways to Reduce Laptop Power Usage

No matter how many watts a laptop uses, what you should do is to let the machine consume less power. And there are some tips:

  1. Never overcharge your laptop since this can consume more power in the process and weaken the battery.
  2. Use the original charger to charge your laptop.
  3. When the charge reaches 10%, plug in the charger. Don’t wait for it to turn off since the process can consume more power.
  4. Check the laptop’s status. If it is overheated, leave it alone for a while without using it.
  5. Pay attention to laptop hardware since the damaged hardware can lead to load and overheating. As a result, high wattage consumption appears.
