How to open Power Settings in Windows 11/10. How to Change Power Plan, Screen Brightness, CPU Performance, etc.

electricityHave a good time everyone!

As practice shows (😉) for inexperienced users it becomes a real discovery only through the settings Power source under Windows it is possible to change a lot of “interesting” things, for example:


In fact, in today’s note, I will address both these and related issues. To get started, let’s look at how to enter these same power settings in general. 👌

Power settings

How to enter

Method 1

So, the easiest and fastest way to access the power options is to click on Win + R (to bring up the “Run” window) and use the command powercfg.cpl (see example below 👇).

Of course, you can find the same settings through the control panel – tab “Hardware and Sound/Power”.

powercfg.cpl - open power settings

Pay attention to the screenshot below 👇 (this tab will look almost the same for you, except for the number of power schemes):

  • menu on the left: You can “adjust” the power, standby, shutdown buttons. display;
  • on the right: Displays power schemes (each can be set manually).

Method 2 (universal // quick change of electrical circuit) 👌

For Windows there is a very interesting utility for working with power settings – 📌Switch Power Scheme (link to the official site). It is especially convenient for laptops – you can change it with two mouse clicks power supply diagram with max. performance to economical (for example, when the device is disconnected from the network).

Of course, with it you can quickly open the power settings (and change them!). See app screenshot below. 👇

Method 3 (Windows 10/11 only)

First you need to open Windows Settings: either by keyboard shortcut win + i; or via the menu START/Settings.

Then go to the section “System / Power and Standby”. On this page you can set the power mode, the waiting time before automatic shutdown. display, etc.

There will also be a link to related parameters – that’s what she needs! 👌 See arrow-5 in the screenshot below. 👇

Method 4* (only for some laptops)

A number of laptops come with special drivers along with the drivers. control centers device (see screenshot below 👇). For example, laptops from Asus, Sony, MSI, Lenovo, etc. may have such centers.

The factthat some settings can be set in these hubs (and windows control panel settings can’t always help!). Therefore, if Windows power settings do not “adjust” some settings, check if you have such a center …

By the way, finding the control center in the laptop is quite simple – by default, a link to it is on the desktop and in the START menu (+ it is easy to find via search). 👇

What is “interesting” through them can be changed

Screen brightness (for laptops/all-in-ones)

In laptops, screen brightness can be a sensitive topic: for example, many people cannot turn off adaptive adjustment (because of which screen brightness constantly changes depending on the image to be viewed). screen, which greatly interferes with normal operation).

To set the optimal brightness settings – open the current power plan settings and go to the advanced options section (👇).

Further in the section “Screen Brightness” set the values ​​for all modes to be the same (in my case 48% 👇), and add. off adaptive tuning. The settings must be identical for mains and battery power.

Power - turn off adaptive setting and set the same brightness

Power – turn off adaptive setting and set the same brightness

By the way, in Windows 11/10 settings (combination win + i) in the section “System / display” there may be another “flag” responsible for adaptive brightness control. It should also be unchecked if you want to disable this option.

2) Spontaneous change in monitor brightness – the laptop itself changes the brightness! Why?


“Adjustment” of CPU performance and temperature

I put the word “adjustment” in quotes (because there is no such option). However, in the current power scheme settings there is a line “Processor Power Management”, where you can limit the max. processor status (sorry for the tautology 😉).

For example, if instead of hundred% (default) put 99% – then we get:

  • disabled Turbo Boost Technology (useful when the CPU behaves erratically);
  • decline CPU performance (and battery consumption!);
  • due to a drop in production – temperature drop;
  • and as a consequence of the previous three points – increased stability operation of the system (even with some problems with the cooling system).


👉 By himself, if your PC is 100% working properly (no overheating, jamming, etc.) – limit the max. Processor state is not required!

The work of power / standby buttons (+ set additional functions for all keyboard buttons)

It’s far from always convenient when the computer is turned off by the power button – instead it would be much more convenient for many to send it in sleep (for example 😉).

To configure how the power buttons work – go to power options and click the appropriate button. side menu (see screenshot below 👇).

Next, select an action for the power and sleep button from the menu.

Extend Laptop Battery Life

Perhaps the power settings affect laptop battery life the most. If you want to slightly extend the battery life of the device, try adjusting the following settings:

  • max limit processor status (instead of 100%, set 90% 👇);
  • decrease screen brightness;
  • reduce the “idle” time after which the laptop automatically shuts down. screen or go to sleep;
  • disable Wi-Fi, Bluetooth adapters (when not in use).

What power settings can prevent a PC from going to sleep

This is a fairly common problem, and sometimes it occurs due to certain “spots” in the power supply…

It’s about wake up timers And media settings: If your PC/laptop won’t go to sleep, try changing these settings as shown in my screenshot below. 👇
