You sometimes want to allocate maximum power to run only one app on Windows. Maybe, you are downloading something overnight, taking a backup of your system, and more. But Windows does not let you allocate all your computer’s resources to run a single app in a straightforward way. So the question is, how to do maximum power saving to run only one app?

This article will share a few ways to reduce your computer’s power consumption. So you can run your apps with maximum power.

How to Do Maximum Power Saving to Run Only One App?

You can use four methods to do maximum power saving to ensure the resource consumption is less and more power can be diverted to one app.

  • Remove Additional Computer Peripherals
  • Safe Mode
  • Wired Internet
  • Run Chrome OS Flex

You will also need admin permission for some of these.

1. Remove Additional Computer Peripherals

One of the effective ways to reduce your computer usage is to remove computer peripherals you don’t need. For instance, if you are just running an app that needs no human interactions. Then you can remove the mouse or keyboard. The idea is to remove devices your computer does not require running.

Additionally, you can turn off your screen lights or lower the brightness. So your computer will not use much power and can run for a few extra hours.

2. Safe Mode

You can also run your computer in safe mode. Safe mode in Windows starts with a basic state with limited files and drivers. Since it does not use too much of your computer power, you can allocate maximum power to run only one app.

To boot your computer into Safe Mode, you can follow the below steps:

safe mode startup settings windows

  • Go to Window Settings.
  • System > Recovery > Click on Restart Now button next to Advanced Startup.
  • After that, click on Troubleshoot > Advanced Options.
  • Next, select Startup Settings and click on Restart.
  • Finally, press the number 4 key using your keyboard to enter Safe mode.

Once you are in safe mode, launch the app, you would like to use, and you are all set.

3. Wired Internet

You can also use wired internet over a WiFi connection. WiFi uses more power than wired internet, so you can save more power on your computer.

Since a wireless connection is known for consuming more energy. As it uses radios to transmit and receive signals. However, if the app does not require an internet connection to run, then you can consider disabling the internet connection.

So Windows will not try to look for Windows update in the background and download it on your behalf, and it will help you to save a bit extra power.

4. Run Chrome OS Flex Using a USB

If you want to run only one app with minimum resources, you can try running Chrome OS Flex using a USB.

Chrome OS Flex is the latest OS by Google. It is lightweight and offers smooth performance on older devices. Additionally, it uses less power compared to Windows.

You can run the OS using a USB stick, which supports many devices. To get started with it, follow the below steps:

  • First, install Chromebook Recovery Utility on your Chrome browser.
  • Once installed, launch it and connect a USB Drive to your computer (8GB Minimum).
