Surely, on more than one occasion, we have left the computer performing a task that requires a long time, be it copying or downloading large files, processing a video that we have edited, rendering a 3D project, for example, and We have taken the opportunity to go out on the street to run an errand, walk the dog or simply stretch our legs and, when we return, our team finds that our PC has entered Sleep mode and the process has been completely paralyzed. The solution to this problem is very simple.
Windows includes different power plans, plans that, based on previously established settings, allow us to get the most out of the computer and prioritize power consumption (ideal function for portable computers). These power plans allow us to configure the time necessary for the screen to turn off, stop the activity of the hard drives, as well as modify the operation of the graphics, the wallpaper and many other functions.
The functions that are based on time, such as the one that allows us to turn off the screen, the hard disks or the sleep mode, do not always work correctly , either because Windows does not want to pay attention to us, it does not detect that it is an application in the foreground working or because an application in the background is affecting the operation of Windows. These problems affect the operation of these options and, even if we have certain configurations established, it is probable that Windows does not detect them and does not perform the appropriate function at all times.
This is usually quite common when we talk about sleep mode, a mode that suspends the operation of the computer to save energy and allows us to return to the same point where we were in a much faster way to hibernation mode (replaced by Quick Start in older versions). modern versions of Windows 10 and Windows 11 when turning off the computer), although the latter consumes less energy and requires disk space that many users are not willing to sacrifice.
Disable sleep mode in Windows
To prevent Windows from misreading these settings, especially when it comes to sleep mode operation and stopping a program from running, the best thing to do is disable it. That is, deactivate the native function of Windows so that the computer does not go to sleep at any time in a power plan of the 3 that it offers us: Economizer, Balanced and High performance. Before making any changes to the operation of Windows Sleep mode, we must be aware that this change only affects the power plan that we select. That is, we can only change the operation of the Windows Sleep mode in High Performance mode without affecting the Economizer and Balanced modes.
In this way, if we want the computer not to go into sleep mode when it is performing any task, we will select the High performance plan, a mode in which, previously, we have deactivated the function that allows it to go into sleep when it is activated. To deactivate the Sleep mode, both in the High performance plan and in the other two available, we must access the Windows power plans through the search box by entering the terms “power plans”. Next, click on Change plan settings , in the power plan that we want to modify.
Next, in the Put the computer in sleep mode section, click on the drop-down box where the time set natively is shown and select the Never option. From now on, when we set High Performance mode, the computer will never go into sleep mode.
We can modify the operation of this mode in any of the plans, but, taking into account that what we want is performance, it is recommended to do it in this particular plan.
