Now that we know how many watts laptops use, let’s take a look at some ways you can save money on your laptop’s running costs.
1. Use power management features
Most laptops come with power management features that can help reduce their power consumption. For example, you can often set the screen to dim after a period of inactivity or disable unnecessary features like the built-in camera and microphone.
2. Use a laptop cooling pad
If your laptop gets too hot, it will use more power to try and cool itself down. By using a laptop cooling pad, you can help keep your laptop at a lower temperature, which will reduce its power consumption.
3. Use a lower screen brightness
The brighter your laptop’s screen, the more power it will use. By reducing the screen brightness, you can save a significant amount of power.
4. Avoid using unnecessary peripherals
Any peripheral devices that are plugged into your laptop will increase its power usage. So if you don’t need to use a DVD drive, web camera, or microphone, consider unplugging them to save power.
5. Choose an energy-efficient laptop model
When it comes to choosing a new laptop, consider models that are designed to be more energy-efficient. These laptops will typically have lower power consumption and may also come with power management features to further reduce their usage.
Overall, it’s clear that laptop power consumption is a major factor to consider when choosing a new computer. By taking steps to reduce your laptop’s power consumption, you can save money on your running costs and help protect the environment too.
