There are several ways to wake up a computer from sleep mode, including moving the mouse, pressing any key on the keyboard, or pressing the power button. Additionally, there are software applications such as Wakeful, Caffeine, and Insomnia that prevent a device from going to sleep by simulating user activity or overriding sleep settings. For remote access, Wake-on-LAN (WoL) is a useful tool that allows users to wake up a sleeping computer over the internet using a Magic Packet, although it requires a complicated setup and may pose security risks. TSplus Remote Support is an alternative solution that provides a secure and integrated approach to remote wake-up and access.

What You'll Learn
Custom power plans
A power plan is a collection of hardware and system settings that manages how computers use and conserve power. Power plans are also known as power schemes. You can create custom power plans that are optimized for specific computers. You can customize the default plans for your systems, create new plans based on existing ones, or create a new power plan from scratch.
There are a number of additional settings you can customize in your newly created plan. Click on the Change plan settings link next to your custom power plan, and then on the Change advanced power settings link. In the Advanced settings tab, you'll find a list of settings you can configure in your scheme, such as disabling sleep mode when the lid is closed (for laptops) or adjusting the hard drive sleep timer. You can also select a high-performance power plan, which prioritizes keeping your computer active over power-saving features.
If you no longer need a custom power plan, you can quickly delete it by opening Settings, clicking on System, then on Power & Sleep, and then on the Additional power settings link. Click the Change plan settings link for the power plan you want to delete, and then click the Delete this plan link. Click OK to confirm, and the custom power plan will be removed from your device.

Advanced power settings
If you want more control over your computer's power settings, you can change the advanced power settings. This will allow you to fine-tune specific aspects of your computer's power usage.
To access these settings, go to the Power Options main menu and click on "Change advanced power settings". Here, you can make adjustments such as disabling sleep mode when the lid is closed (for laptops) or changing the hard drive sleep timer. Disabling sleep mode can be particularly useful if you frequently work on long-term projects or use complex software that takes a while to load, as it ensures your system is always ready when you need it.
Additionally, you can create a custom power plan through the Control Panel, allowing you to save unique settings profiles for different scenarios, such as work, travel, or home. For example, you can set your laptop to hibernate when you close the lid, or you can adjust the settings to make your computer go to sleep when you press the power button. Hibernate mode saves your computer's current state to the hard drive and then powers down, using no power. It takes longer to resume from hibernation than sleep, but it uses less power and is useful when you won't be using your laptop or tablet for an extended period without a chance to charge the battery.
If you want to prioritise keeping your computer active over power-saving features, you can switch to a high-performance power plan, typically found under "Show additional plans" in Power Options. You can also use third-party software tools like Wakeful, Caffeine, and Insomnia to keep your computer awake. These tools simulate user activity or override sleep settings, ensuring your system remains active without manual adjustments.

Third-party software
There are several third-party software tools that can be used to prevent a computer from going to sleep and even to take control of a sleeping computer.
One such tool is Microsoft PowerToys Awake, which is a utility that provides a set of useful utilities to tune and streamline your Windows experience for greater productivity. It helps prevent your computer from sleeping during long-running tasks, presentations, or downloads, ensuring your work continues uninterrupted. PowerToys Awake does not modify any of the Windows power plan settings and does not depend on a custom power plan configuration. Instead, it spawns background threads that tell Windows that they require a specific state of the machine.
Another option is to use tools like Wakeful, Caffeine, and Insomnia, which are popular applications that prevent your device from going to sleep by simulating user activity or overriding sleep settings. These tools ensure your system remains active without needing manual adjustments. For example, some tools simulate brief mouse movements or keyboard inputs to keep the system from going idle.
Additionally, there are other third-party solutions like TSplus Remote Access, which offers a seamless and secure way to wake up and access a remote workstation through a single platform. It integrates Wake-on-LAN, automatically waking the remote device when needed.
It is important to note that keeping your computer awake all the time using third-party software can have potential drawbacks, such as increased wear and tear on mechanical hard drives (HDDs) and solid-state drives (SSDs), as well as faster degradation of cooling fans due to continuous operation. Therefore, it is recommended to download third-party tools from trusted sources and keep the software up-to-date to avoid vulnerabilities and compatibility issues.

Remote access
Wake-on-LAN (WoL)
WoL is a feature that enables users to remotely wake up a sleeping computer over a local network. It requires proper setup in BIOS, Windows settings, and network configurations. To use WoL, you need to ensure that the computer's network card supports the feature, which is typically available on modern Ethernet adapters but rare on wireless adapters. You can send a "magic packet" from another device on the same network, such as a phone or laptop, to wake up the sleeping computer. However, it's important to note that WoL may not work if the computer is behind a router or multiple routers.
Wake-on-WAN (WoW)
WoW allows remote wake-up over the internet but introduces security risks by requiring port forwarding or a VPN. It involves sending a "magic packet" to the router's external IP address instead of the computer's internal IP address. WoW is considered more complex than WoL and may require additional tools to access and control the computer after waking it up.
Software Solutions
Several software solutions are available to facilitate remote access to sleeping computers:
- TSplus Remote Support: TSplus offers a secure and seamless way to manage remote access. It integrates remote wake-up with access through a single platform, eliminating the need for multiple tools. It provides enterprise-grade security, scalability, and cost-effectiveness, supporting multiple users and remote offices.
- TeamViewer: TeamViewer allows users to wake up sleeping PCs connected to their account and provides remote desktop control.
- Jump Desktop: Jump Desktop offers Wake-on-LAN functionality, but it may require keeping one computer in the local network always on to wake up other devices.
- Chrome Remote Desktop: Chrome Remote Desktop supports Wake-on-LAN, enabling users to access their workstations remotely.
- Microsoft Remote Desktop: Microsoft's Remote Desktop tools allow users to hibernate remote computers, but issues with putting them to sleep have been reported.
System Settings and Tweaks
To enable remote access and wake-up functionality, it may be necessary to adjust certain system settings:
- Power Options: Ensure that the computer is set to not go to sleep when connected to a power source. This can be adjusted in the Power Options applet in the Control Panel or the Energy Saver options on macOS.
- Fast Startup: In some cases, disabling the computer's fast startup feature may be necessary for Wake-on-LAN to work properly.
- BIOS Settings: Tweaking the power options in BIOS may be required, such as enabling Wake-on-LAN or adjusting sleep and wake settings.
- Windows Settings: On Windows, enable Wake-on-LAN in the Device Manager and adjust network adapter settings.
By combining the appropriate software solutions, system tweaks, and features like Wake-on-LAN or Wake-on-WAN, users can achieve remote access to sleeping computers, enhancing their ability to manage and control their devices from a distance.

Preventing random wake-ups
If your computer randomly wakes up from sleep mode, there are several steps you can take to prevent this from happening. Firstly, determine the cause of the wake-ups by opening the Power-Troubleshooter from the Event Sources drop-down menu, which will show you all the recent wake-up times and their causes.
If the cause is a specific device, you can disable its wake permissions. To do this, open the Start menu, search for "Device Manager," find the device in the resulting list, right-click on it, select "Properties," then open the Power Management tab and uncheck the "Allow this device to wake the computer" option. Common culprits include USB devices, the Ethernet controller, and the mouse.
You can also try disabling all wake timers for both battery and plugged-in power sources. To do this, go to Control Panel > System and Security > Power Options, choose a balanced plan, click "Change plan settings," then "Advanced power settings." Click on the Sleep option, disable the "Allow wake timers" option, and then disable all wake timers.
Another potential cause of random wake-ups is Windows Update. To prevent this, try using Windows Update's built-in tools to schedule updates and reboots during specific active hours.
If you want more control over your power settings, you can go back to the Power Options main menu and click on "Change advanced power settings." Here, you can fine-tune specific aspects such as disabling sleep mode when the lid is closed (for laptops) or adjusting the hard drive sleep timer.
Additionally, you can use third-party software tools like Wakeful, Caffeine, and Insomnia to prevent your computer from going to sleep. These tools simulate user activity or override sleep settings, but be sure to download them from trusted sources to avoid malware or compatibility issues.
Finally, a simple workaround to prevent your computer from going to sleep is by playing a picture as a slideshow on Windows Media Player.
