Issue: How to disable Sleep Mode in Windows?

Hello. Is there a way to disable Sleep Mode in Windows? My PC keeps going to sleep when I leave it for a longer time. Any tips would be appreciated.

Solved Answer

Sleep Mode is a Windows power-saving feature that puts your computer into a low-power state. This feature is useful when you need to step away from your computer for a short period of time but don't want to completely shut it down. Your computer uses very little power while in Sleep Mode, but it remains on, making it faster to resume working than a full restart.

When you put your computer to Sleep, Windows turns off the display, hard drives, and other devices to save energy, but the computer's memory remains powered on. This means you can easily restart your computer and pick up where you left off. Sleep Mode differs from Hibernation in that the computer saves its current state to the hard drive before shutting down completely.

Some people, however, may wish to disable Sleep Mode in Windows for a variety of reasons. For example, if you're downloading a large file or performing a lengthy task that will take several hours to complete, Sleep Mode may interrupt it, causing you to lose progress. Furthermore, some people may disable Sleep Mode to save power when running on battery power or when not using their computers for an extended period of time.

Fortunately, there are several ways to disable Sleep Mode in Windows, including the Control Panel's Power Options, Registry Editor, and Group Policy Editor. Command Prompt and PowerShell commands are also available. This guide will show you 10 different ways to disable sleep mode in Windows.

Access geo-restricted video content with a VPN

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
