If you want to wake your computer from sleep mode without having to physically press the power button, there are several methods you can use. One common method is to use a Wake-on-LAN (WoL) magic packet, which can be sent from another computer or device on the same network, such as a phone or laptop. This can be done using software such as NirSoft WakeMeOnLAN or TeamViewer, which has built-in Wake-on-LAN support. Alternatively, you can use an Android app like WOL Magic Packets Widget to wake up your PC from anywhere, regardless of whether you currently have access to another computer or not.

What You'll Learn
Using Wake-on-LAN (WoL)
Wake-on-LAN (WoL) is a networking standard that allows computers to be woken up from sleep mode within a local area network (LAN). It is a useful feature for those who want to access their computers remotely without having to leave them turned on all the time.
To enable WoL, your computer should be connected to an ATX-compatible power supply with an extra +3.3V voltage rail. You can check if your Windows computer has the WoL software feature by clicking the "Start" button, typing "device manager", and opening the "Device Manager" window. In the "Device Manager" console, expand the "Network adapter driver", right-click your network adapter, click "Properties", and select the "Advanced" tab. Here, you should be able to find "Wake on Magic Packet" and "Wake on Pattern Match".
Once WoL is enabled, you can use software like NirSoft WakeMeOnLAN to scan for and power up WOL-capable PCs on your local network. Alternatively, you can use remote access software like TeamViewer, which uses the same WOL technology. To enable WoL in TeamViewer, open the client and press "Extra" > "Options". Once enabled, you can launch WoL by clicking the "Wake Up" button for your PC, listed under the "Computers & Contacts" menu.
It is important to note that WoL is typically sent as a specially constructed Ethernet packet or "magic packet" to a client computer connected to the same LAN. This packet contains important information such as the target client's MAC address and network broadcast address. However, there are security considerations when implementing WoL as it uses the concept of direct broadcast. To enhance security, features like "SecureOn" allow users to store a hexadecimal password within the NIC, which decreases the risk of successful brute force attacks.

Using a remote access tool like TeamViewer
TeamViewer is a remote access tool that can be used to wake a computer from sleep mode. It uses a feature called Wake-on-LAN (WoL) to remotely reactivate a computer from a low-power or powered-down mode.
To use TeamViewer to wake a computer from sleep mode, follow these steps:
- Launch TeamViewer on your computer.
- Go to the "Settings" menu and click on "Account Assignment" under the "General" tab.
- Assign your TeamViewer account by entering your credentials and clicking "Assign".
- Click on "Configure" next to Wake-on-LAN.
- Add the TeamViewer ID of a computer that is on the same local network and is always running. This computer will act as a "middleman" to forward the wake-up request to the remote computer.
- Enter the TeamViewer ID and click "Add", then "OK".
- Navigate to the "Devices" section and select the target device you want to wake up.
- Select "One-click control" to quickly wake up the sleeping device.
- Enter your computer password to enable unattended remote access.
It is important to note that the remote computer must have its WoL settings enabled for this process to work. Additionally, the computer's network interface card (NIC) must be configured to receive power and be capable of receiving "magic packets".
TeamViewer provides a simple and secure process to wake up, access, and control devices remotely. With its built-in Wake-on-LAN support, you can maintain and control machines even when they are turned off or in low-power modes.

Ensuring your network router is properly configured
To ensure your network router is properly configured, you should first check that your router uses the latest Wi-Fi technology and upgrade your router firmware regularly. You can also get a new router every year to ensure consistent speeds and reliable performance.
Next, you should change the default router username and password. If you don't, attackers can easily guess them and log into your router, compromising your network. You should also enable only the services you need and block all others.
You can also change your network name and password, as well as adjust the security level. You can do this by logging into your router's firmware. The IP address of your router is typically 192.168.1.1, but this may vary, so check first. You can usually find this by going to Settings > Network & Internet > Status > View hardware and connection properties.
You can also use an Ethernet cable to connect your modem to the WAN/WLAN/Internet port on your router, and connect your computer to the “1”, “2”, “3”, or “4” port on the router. You can then access your router's configuration page through a web browser.
Finally, if you have multiple routers, configure each to use a different channel, especially if they are close to each other.

Using a Wake-on-LAN app on another device
To wake your computer from sleep remotely, you can use a Wake-on-LAN (WoL) app on another device. This feature is designed to wake up another computer on your network, so it won't work for computers on another network. Before using WoL, you need to enable it in your computer's BIOS settings. To do this, reboot your PC and press a specific key (usually Delete, F2, or another function key) to enter the BIOS menu. Find the Wake-on-LAN option, which may be under sleep and wake settings or part of the Resume By PCI-E Device setting.
There are several WoL apps available for different devices. For Windows PCs, NirSoft's WakeMeOnLan is a popular option. It scans the network and provides a list of devices, so you don't need to remember IP addresses. Simply click on the device you want to wake up and hit "Wake Up". Another similar tool is Depicus, which requires you to enter the IP address, MAC address, subnet mask, and port number for the remote PC.
If you're using an Android device, you can try the WOL Magic Packets widget or the Wake On Lan app. For iOS devices, Mocha WOL is a good option. These mobile apps allow you to wake up your PC with the tap of a button, sending a "magic packet" to your computer.
Before using a WoL app, ensure your network router is properly configured to allow remote access to your PC, including setting up appropriate firewall rules. Additionally, make sure that power-saving options on your NIC are disabled. Go to the Power Management tab in your network interface properties and ensure that the option "Allow the computer to turn off this device to save power" is not checked.

Using a separate program to wake up your PC
If you want to wake up your PC remotely, you can use a 'Wake-on-LAN' (WoL) magic packet. This can be done through software such as NirSoft WakeMeOnLAN or TeamViewer.
To use WakeMeOnLan, you will need to download the software from the NirSoft website and extract the ZIP file. Once you have launched the software, you can begin scanning for WOL-capable PCs on your local network by clicking 'File > Start Scanning', or add a PC manually by clicking 'Add New Computer'. Once you have a PC in your saved list, you can power it up by selecting it and pressing the 'Wake Up Selected Computers' icon. You can also right-click and press 'Wake Up Selected Computers', or press F8 on your keyboard.
TeamViewer is another option that uses the same WOL technology. It is completely free for non-commercial use, and allows you to connect to your PC from a variety of operating systems. To use WoL with TeamViewer, you will first need to enable Wake-on-LAN in your TeamViewer settings. To do this, open the TeamViewer client and press 'Extra > Options'. Once WOL is enabled, you can launch it by clicking the 'Wake Up' button for your PC, listed under the 'Computers & Contacts' menu.
If you are using an Android device, you can also use the WOL Magic Packets widget to wake up your PC from anywhere.
Before using a remote wake-up tool, you will need to ensure that your network router is properly configured to allow you to access your PC, including setting up appropriate firewall rules.
