If you want to wake your computer from sleep mode without having to get up and press the power button, you can do so remotely with Chrome Remote Desktop. This can be achieved by enabling Wake-on-LAN, which allows you to turn on your computer using its network connection. To enable Wake-on-LAN, you need to access your computer's BIOS/UEFI settings and ensure that Wake-on-LAN or Wake on Magic Packet is enabled. Once enabled, you can use Chrome Remote Desktop to send a magic packet to your computer, which will wake it from sleep mode and allow you to establish a remote connection. This method may require some trial and error, and there are alternative tools available such as TeamViewer, NirSoft's WakeMeOnLan, and mobile apps like Mocha WOL (iOS) or Wake On Lan (Android).

What You'll Learn
Using Chrome Remote Desktop
Chrome Remote Desktop is a tool that allows users to remotely access another computer via the Chrome browser or mobile device. While it is typically used to access and control a remote PC, there have been reports of it being used to wake a sleeping computer.
In a Reddit post, a user describes their experience with Chrome Remote Desktop, where they were able to wake their remote PC from sleep and connect to it successfully. However, they noted that this behaviour stopped working after a while, and they had to leave their PC awake to connect remotely. Another user responded, speculating that the difference in behaviour could be due to the Windows version they were running. They suggested that Windows Pro allows remote access on the network, while the Home version does not.
To ensure your PC can be woken up remotely, you can try the following:
- Check your power and sleep settings: Ensure that your PC is indeed in sleep mode and not in hibernate or power-saving mode.
- Enable "Wake-on-LAN": Check your motherboard settings and enable the "Wake-on-LAN" or "Magic Packet" option, which allows a computer to be turned on remotely from a powered-off state.
- Use Caffeine: Install a tool like Caffeine, which prevents your PC from sleeping and only shuts down non-vital functions.
- Task Scheduler: If you're using Windows 10, you can try using the Task Scheduler to wake your computer with a simple checkbox option.
It's important to note that the ability to wake a sleeping computer with Chrome Remote Desktop may vary depending on your hardware, software, and network configurations. The behaviour of Chrome Remote Desktop can also change over time, as updates and changes to the software or operating system may impact its functionality.

Wake-on-LAN
The basis for the Wake-on-LAN industry-standard mechanism was created around 1994 by AMD in cooperation with Hewlett-Packard, who co-developed AMD's Magic Packet Technology. The term "Magic Packet" is an AMD trademark. Wake-on-LAN saw wide adoption starting in October 1996, when IBM formed the Advanced Manageability Alliance (AMA) with Intel. In April 1997, this alliance adopted the Wake-on-LAN technology.
The magic packet is broadcast on the data link layer to all attached devices on a given network, using the network broadcast address; the IP address is not used. Wake-on-LAN can operate across any network in practice, given appropriate configuration and hardware, including remote wake-up across the Internet. In order for Wake-on-LAN to work, parts of the network interface need to stay on, consuming a small amount of standby power.
To enable Wake-on-LAN, you need to enable it at the hardware level in the computer's BIOS. To do this, reboot your PC and press a specific key at the boot screen, usually Delete, F2, or another function key. Once you enter the BIOS menu, look for the Wake-on-LAN option. On some machines, it will be very clearly labelled in the sleep and wake settings, while on others it may be part of a different setting. Toggle that setting to Enabled. Once rebooted into Windows, you need to enable Wake-on-LAN on the OS side. Click the Start menu, search for "Device Manager", then click the entry to launch the Device Manager. Find the Network Adapters section in the Device Manager, then expand it to reveal your network interfaces. Click the Advanced tab, then scroll down to Wake On Magic Packet and ensure it's set to Enabled using the drop-down box on the right. Next, click the Power Management tab in the same window and check two boxes: "Allow This Device to Wake the Computer" and "Only Allow a Magic Packet to Wake the Computer".
There are also apps available that can help automate the process of waking up computers using Wake-on-LAN.

Enable Wake-on-LAN in BIOS
To enable Wake-on-LAN (WoL) in BIOS, you'll need to perform the following steps. Firstly, it's important to note that BIOS menu systems vary, so the exact steps may differ. However, to enter the BIOS, you typically press a specific key as you boot your computer, such as Delete, Escape, or F2. Your boot screen should provide instructions on the key to press. Once you've entered the BIOS, navigate to the Power Management or Advanced Options section. Within these options, you should find the Wake-on-LAN setting. Ensure that it is enabled, and if you see an option for ""Deep Sleep Mode," make sure it is disabled.
It's worth mentioning that Wake-on-LAN functionality is generally disabled by default and may be buried within several menu options, depending on your BIOS manufacturer. For example, on an HP computer, the Wake-on-LAN setting is found near the "resume after power failure" option, while on an ASUS motherboard, it may be located under "Power on by PCIE/PCI."
In addition to enabling Wake-on-LAN in BIOS, you may also need to adjust your Windows settings. For Windows 10, go to the Power Options in the Control Panel and select "Choose what the power buttons do" in the upper left corner. For Windows 11, the process is similar: open the Start menu, type "Device Manager," and expand the "Network Adapters" section. Right-click on your network card, go to Properties, and then click on the Advanced tab. Locate the "Wake on Magic Packet" setting and change the value to "Enabled."
By following these steps, you should be able to successfully enable Wake-on-LAN in BIOS and configure your Windows settings to take advantage of this feature.

Use of 'Magic Packets'
Wake-on-LAN (WoL) is a feature of most modern computers that allows users to wake up a sleeping or powered-off computer remotely. This is achieved by sending a "magic packet" to the computer's network card, which contains enough power to remain in standby mode even when the rest of the system is off. The magic packet contains a specific sequence of data, including six instances of the largest possible byte value (FF) and sixteen instances of the card's six-byte MAC address.
To enable the use of magic packets, you need to ensure that your computer's network adapter supports WoL. You can do this by accessing the Device Manager and checking the settings for your network adapter. Enable the "Wake on Magic Packet" or "Wake-on-LAN" option if available. Additionally, you may need to adjust power management settings to allow the device to wake the computer.
It is important to note that while Ethernet adapters commonly support WoL, wireless adapters rarely do. If you are using a wireless adapter, you may need to connect your computer to an Ethernet connection to receive the magic packet.
For remote wake-up outside of your local network (Wake-on-WAN), the process is more complex. The magic packet needs to be sent to the router's external IP address, and port forwarding is used to forward the packet to the correct computer. However, this use case is not standard for Wake-on-LAN, and the success of this method depends heavily on your network setup.
Some users have reported issues with the magic packet not working as expected, even with the correct settings enabled. In such cases, it is recommended to check power settings, BIOS settings, and network adapter compatibility.

Remote access tools
To enable remote access to your computer, you can use the Wake-on-LAN (WoL) feature, which allows you to turn on a computer that is powered off or asleep by sending a "magic packet" from your phone or laptop. WoL needs to be enabled at the hardware level in the 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 to access the BIOS menu. Once in the menu, look for the Wake-on-LAN option, which may be found in the sleep and wake settings or under a similar name. Toggle the setting to "Enabled".
It is important to note that not all network adapters support WoL. Modern Ethernet adapters typically support WoL, but wireless adapters rarely do. If you are using a wireless adapter, you will need to send the magic packet over Wi-Fi, but the receiving computer will need to be connected via Ethernet. Additionally, some motherboard BIOS requires WoL to be turned on to permit remote wake-up, so it is recommended to access your motherboard's BIOS/UEFI to ensure WOL capabilities are enabled.
There are also other remote access tools available that support WoL, such as TeamViewer, NirSoft's WakeMeOnLan, and Depicus. For mobile devices, Mocha WOL (iOS) or Wake On Lan (Android) can be used. These tools allow you to wake up any sleeping PC connected to your account or by entering the correct IP address and other details.
Another workaround suggested by a user is to use Caffeine, which keeps your PC awake by updating your screen-saver settings so that your PC never sleeps, only shutting down non-vital functions.
