What is the power scheme in Windows and how to switch between them
Mobile devices are very useful, especially if you travel a lot, but the batteries in such devices usually provide a limited supply of energy. Thus, it is very important to pay attention to the power plans and their settings, as it makes a huge difference in how long it will operate your laptop or tablet without recharging. Of course, Windows 7, Windows 8 and 8.1 include the necessary tools to view all available power schemes, and the ability to easily and quickly switch between them. Let’s learn how it works.
What is the power management scheme?
The power plan is a collection of hardware and system settings that manage how your computer uses energy. The available power schemes depend on the type of PC and the settings that the manufacturer made the power plans available in Windows by default.
Some meal plans are designed to provide high performance to the detriment of autonomy, while others are set to maximize battery life, the device performance is compromised.
All the available power plans, you can see in the «power supply».
How to open the «power options» in Windows 7 and Windows 8
In Windows 7 you need to open «start menu» and type in the search string the first few letters of the word «power». Then, in the list of search results select the «power supply».
In Windows 8.1, search works well, so you can simply enter a keyword on the start screen, and select the appropriate result.
There is another method, which is applicable to both Windows 7 and Windows 8 – need to open «control Panel» and go to «Hardware and sound -> power options».
If you are using a mobile device, you have to be familiar with the little battery icon in the notification area.
Clicking on it opens a small window with battery indicator. In this window you can see how many charges left. In addition, it is possible to select one of two power plans. If you click on the link «more power options» at the bottom of this window, open the menu «power supply» with all the available power plans.
In Windows 8.1 there is another way to quickly get to this window simply right click on the «start» button, and then select the item «power Management» in the context menu. This context menu can also be opened with the keyboard shortcut Win + X.
After opening the window «power supply» you will see only two schemes that exist on your computer. To see the rest of the scheme, you need to click on the arrow under «Show additional power plans».
The number of available power schemes depends on the device you use. This is due to the fact that manufacturers typically add their own schemes specially designed for a particular device. In addition, in some cases, they remove the power scheme that is available in Windows by default, and substitute their own. This suggests that you, too, can create their own plans with their own settings.
What is the difference between the standard power plans
As mentioned above, the power plan contains the hardware and system settings that influence the power management of the computer. By default, Windows provides three schemes of power supply: «energy Saving», «Balanced» (the one that is recommended by Microsoft) and «High performance».
The most notable changes made to Windows when selecting a power scheme affect the brightness of the display and the computer is idle, after which the display and computer should go to sleep. By default, these settings depend on the type of computer, and whether he uses battery or connected to the supply. The following is a comparison of settings for each power scheme for each of the two modes: battery mode and plugged in.
You should note that the above table do not show all than run a power scheme, but in one of the following articles we will discuss more advanced control schemes.
How to choose a power scheme
The fastest way is to open the battery meter, by clicking on the battery icon in the notification area. In this window, you can select one of two power plans.
If you want to choose from all the available schemes, you can do it in the «power supply».
On laptops or tablets, you can also use the «Windows mobility Center» which can be opened by pressing Win + X on your keyboard and then select the appropriate option from the context menu.
After selecting a scheme, along with changing the power management settings will change the estimated time your device’s battery life.
Now you know what power scheme, what are the most important differences between them and how to switch between them. I hope you found this article useful and if you have any questions, ask them in the comments.
