How to lower the cost of running a laptop

Laptops are designed to run on batteries, so they're inherently efficient. Typical use draws 30–60W from the charger, with gaming laptops and mobile workstations reaching 100–200W under load. Even working full time on a laptop costs only a few dollars a month in most states.

  • Use battery-saver mode and lower screen brightness.
  • Unplug once charged if your laptop lacks charge-limiting features.
  • Put it to sleep instead of leaving it idle overnight.
