10 Tips To Reduce Laptop Electricity Usage

Reduce the electricity usage and running cost of your laptop with these 10 easy to implement tips. Many of these also help save battery life when the laptop is not plugged in.

  1. Change your sleep settings. Entering sleep mode sooner during inactivity will reduce the amount of electricity that your laptop uses. ENERGY STAR notes that this can save $15 per computer annually. You’ll likely save as much as this if you’re using your device for extended periods, e.g. while working from home. The default sleep mode time, upon shipping, for laptops ranges from 4 minutes to 30 minutes. Based on over 1,000 laptops, the most common sleep mode time is 10 minutes, with 18 minutes being average.
  2. Don’t forget your display sleep mode. Many laptops have a display sleep mode, which is different from the main sleep mode feature. Display sleep mode, as the name suggests, will mainly save electricity by putting the screen to sleep – background apps may continue to run. Consider setting your display sleep mode the same as your sleep mode (not less) as this can save electricity. Based on over 1,000 laptops, the default time, upon shipping, for display sleep mode ranges from 4 minutes to 15 minutes, with 10 minutes being the most common and 9.5 minutes being the average.
  3. Turn on power saving mode. Most laptops come with a power saving mode. This mode saves electricity by reducing the performance of certain laptop features. Most features will still perform to a satisfactory level, so do consider checking out this mode.
  4. Turn on battery saving mode. This is different from the power saving mode and works when your laptop is disconnected from the mains. As the name suggests, this will save battery, which means that less electricity will be required to charge your laptop when it’s plugged back in.
  5. Reduce screen brightness. Display brightness significantly impacts the amount of electricity that your laptop uses. The lower the brightness, the less power will be consumed.
  6. Disable certain apps at certain times. Many apps can run unnecessarily in the background and on start up. These make your laptop work harder, and, as a result, consume more electricity. Consider disabling apps where appropriate (and only if you’re confident that you won’t break anything!).
  7. Turn off unused features and devices. Consider turning off and disconnecting ancillary devices if they’re not in use, e.g. a monitor or a mouse. Also consider switching off features such as Bluetooth, WiFi and backlighting from your keyboard, if they’re available and not being used.
  8. Reduce heat. Laptop fans obviously consume power and turn on when required. They’re required more when there is less ventilation around the device, e.g. when the laptop is sitting on and surrounded by bedding. Consider where you place the device when you’re using it, and try to allow for good heat dissipation. This will reduce the amount of electricity required to cool the laptop.
  9. Switch off and unplug. Most laptops continue to consume electricity when completely turned off and still plugged in. Despite using less electricity, Off mode can actually use more electricity than Sleep mode per day due to the extended period of time that the laptop is in that mode. So, to save energy, remember to unplug.
  10. Consider switching energy provider. If available in your area and if appropriate, consider switching your utility company. Shop around because energy providers tend to offer significant discounts to attract new customers. This will not just reduce your laptop’s electricity costs, but also the cost of running all of your electrical appliances.

The vast majority of these tips have the added benefit of reducing your carbon footprint. If you’d like to reduce it even more, get in touch with your energy provider and ask about their Green energy options.

How Much Power Does A Laptop Use When Plugged In?

While notebooks and netbooks generally use less power than high-end laptops, the power consumption of a laptop depends on the size of the screen and specs, typically you will find power consumption as low as 20 watts and up to 100 watts when a laptop is running off the battery.

When a laptop is on a charge while in use, power consumption will increase from 10 to 20 percent. It is estimated that the average power consumption of 14 to 15-inch laptops is 60 watts per hour, so a laptop that is using 60 watts when used for 6 hours a day while in a plug will cost $0.0648 per day (if you are in NewYork).

Do Desktops Consume More Power Than Laptops?

Most laptops today have a configuration that uses less power than older models. This is due to more efficient processors, more powerful graphics, and an updated operating system. Laptops that use less power typically have a battery that can last for up to three hours longer than laptops with older configurations.
