There are many ways to wake up a computer from sleep remotely. Some of the most popular methods include using Wake-on-LAN, which allows you to turn on your computer using its network connection, and apps such as WOL Magic Packets Widget, which can be used on your phone or laptop. Other methods include using remote support servers such as R-HUB, or remote access tools such as TeamViewer, which also support Wake-on-LAN. Additionally, you can use Moonlight Streaming, which has a Wake-on-LAN feature, or Task Scheduler to wake up your PC at a fixed time.

Using a Wake-on-LAN app
To wake your computer from sleep remotely, you can use a Wake-on-LAN (WoL) app. This feature allows users to wake their computers from a sleep or powered-off state, enabling access to files, running updates, or performing tasks without being physically present.
Firstly, you will need to enable Wake-on-LAN at the hardware level in your computer's BIOS. To do this, reboot your PC and press a specific key (usually Delete, F2, or another function key) at the boot screen. Once you enter the BIOS menu, find the Wake-on-LAN option and toggle it to 'Enabled'.
Next, you will need to install a Wake-on-LAN app on another device, such as a phone or laptop. Some popular options include TeamViewer, NirSoft's WakeMeOnLan, and Depicus. These apps will allow you to send a "magic packet" to your sleeping computer, which will wake it up.
To use TeamViewer, simply open the program and click the "Wake Up" button to wake up any sleeping PC connected to your account. With NirSoft's WakeMeOnLan, the app will scan the network and provide a list of devices, so you can select the correct one and hit "Wake Up". If you're using Depicus, you will need to enter the IP address, MAC address, subnet mask, and port number for the remote PC.
Additionally, if you use a NAS device or Raspberry Pi, you can SSH into it and use the command line to send the magic packet. As long as the magic packet comes from inside the network, Wake-on-LAN should work without any issues.
It's important to note that the network card of the computer being woken up needs to support Wake-on-LAN. Most modern Ethernet adapters will support it, but wireless adapters rarely do. So, if you're using a wireless adapter, you will need to send the magic packet over Wi-Fi, and the receiving device will likely need to be connected via Ethernet.

Sending a 'magic packet'
A "magic packet" is a small amount of data specific to the MAC address of the network card. When a computer in standby mode receives this packet, it will respond by turning on the system. This is very useful for remote control situations.
To send a magic packet, you will need to know the MAC address of the computer you want to wake up. This is the physical address of the computer. You will also need to know the IP address of the computer. This can be your external IP or the Dynamic Domain address.
There are several ways to send a magic packet. One way is to use a mobile app such as the WOL Magic Packets widget for Android. Alternatively, you can use a remote support server such as R-HUB. If you are using Windows, you can also try using the Task Scheduler to wake up the PC.
Once you have the necessary information and tools, you can send the magic packet to the sleeping computer. The computer should then wake up and you can establish a remote connection.

Using a VPN
To use WoL, your computer must be able to receive a "magic packet" on Port 9. This is a small data signal that is broadcast to the network interface card (NIC) of the target device. To ensure your computer can receive these packets, you need to configure your router to always forward them to your computer. This means your computer needs to have the same IP address, which can be achieved by assigning it a static IP address in your router's settings.
When using a VPN, you are essentially connecting to your network remotely. This means that you can send a magic packet to your computer over the VPN connection, as long as WoL is enabled on the target device. To enable WoL, you may need to configure your device's BIOS (Basic Input/Output System) and ensure that the NIC is supplied with power and capable of receiving magic packets.
There are several tools available that support WoL, such as TeamViewer, NirSoft's WakeMeOnLan, and Depicus. These tools can make it easier to wake your computer remotely, and some even offer additional features like remote access and control.
It is important to note that while WoL works on most modern Ethernet adapters, it may not be supported by wireless adapters. Additionally, some computers may only support WoL from sleep mode, while others may allow it to wake up from a powered-off state. Therefore, you may need to tweak power options in the BIOS or Windows Control Panel to ensure WoL functions as expected.

Using remote desktop mode
Remote desktop mode allows you to access your computer from another device, but it can be tricky to wake your PC from sleep remotely. One way to do this is to use Wake-on-LAN (WoL), which requires you to enable the setting in your computer's BIOS/UEFI. This will allow your computer to go to sleep instead of powering off completely, and it will listen to the Ethernet port for a "magic packet" to wake up and power on.
To set up WoL, you will need to know your computer's MAC address, IP address, and subnet mask. You can find your MAC address by browsing your router's status page when the computer is connected to the network. For your IP address, you can use your external IP or create a Dynamic Domain address. You can also use a free tool like Wake On LAN GUI from Depicus or the Wake On LAN Tool from ManageEngine. Once you have the necessary information, follow the tool's instructions to send the magic packet and wake up your computer.
Another option is to use a separate WakeOnLan program, port forwarding only for the magic packet, and a VPN for RDP access. However, opening the firewall for direct RDP access is not recommended for security reasons. Additionally, you can try disabling the "Only allow management stations..." option to activate the "Wake on pattern" functionality. This will configure the network card to recognize specific packet headers, but it will wake the computer on any connection attempt, not just RDP.
It's important to note that some modern motherboards with UEFI may have WoL enabled by default, but older boards generally do not. Consult your motherboard's documentation or manufacturer for specific instructions on accessing and enabling WoL in the BIOS/UEFI. Additionally, make sure that "Allow the computer to turn off this device to save power" is not checked in the Power Management settings of your network interface properties.

Disabling 'Only allow management stations'
Disabling the "Only allow management stations to bring the computer out of standby" option can be done through the following steps:
Firstly, it is important to identify the problematic hardware that is causing the computer to wake up. To do this, open the Start menu, search for "cmd", right-click on the Command Prompt entry, and choose "Run As Administrator". Then, type the following command and press Enter:
This will help identify the hardware or software that is causing the computer to wake up. Once the problematic hardware is identified, the next step is to open the Device Manager by searching for it in the Start menu. Right-click on the device in question, select "Properties", and then open the "Power Management" tab. Here, the option "Allow This Device to Wake the Computer" should be located and can be unchecked.
If the computer still does not stay asleep, the next step is to enter the BIOS setup. This can usually be done by pressing a specific key, such as Delete or F2, when the computer first boots up. The boot screen will often indicate the correct key to press. Once in the BIOS setup, the USB waking option can be disabled if it is available.
Additionally, there are other options available within the "Power Management" tab, such as "Allow the computer to turn off this device to save power" and "Allow this device to bring the computer out of standby". Disabling these options can also help prevent the computer from waking up unexpectedly.
It is worth noting that some computers may have different power management settings and options available, so it is important to review the specific settings available for your device.
