When you put your PC in sleep mode, you usually need to press a button before it will wake back up. This can be inconvenient in a number of different scenarios such as getting snowed in and not being able to get to your office or being on vacation and not having access to some files on your home computer.
If you want your computer to perform some sort of action (i.e. automatically run downloads, gain remote access to your computer anywhere, anytime, etc.) there are ways that you can wake up your computer without actually touching it.
Not only can you wake it up remotely, but you can access files and take control of the system!
Wake On Lan
Wake On Lan (WoL) is a protocol for waking your computer up remotely from sleep or hibernation – There are a variety of Software and Tools to Help with Wake-On-Lan that can be found here to assist you with the WOL process.
As long as the computer has access to a power source and the firmware is correctly configured to allow Wake On LAN for the NIC, WoL will work.
With WoL you can also use your smartphone to turn on a computer via your local network or the Internet.
WoL is useful if you plan to access your computer remotely but want it to be in a low power mode when not in use.
Network Administrators find this tool useful because it allows them to perform scheduled maintenance tasks without having to physically visit each computer on the network.
It is also great if you are traveling and you want to access your home computer via a laptop or as mentioned above, you get snowed in and need to work from home.
Automated Scheduled Wake Time
You can also make your computer wake from sleep automatically directly in the computers OS.
If you are running Windows, this is done via the Task Scheduler under Programs.
On a MAC this would be done under System Preferences–>Energy Saver.
Remotely Trigger Wake Up
There are many WoL Magic Packets that can remotely trigger wake up of your computer.
In order to do so you need to do the following:
- Assign your computer a Static IP address
- Configure port forwarding in your router
- Turn on WoL in your PC’s BIOS
- Configure your network adapter’s power settings in Windows to allow it to wake the PC
- Set up an external IP DNS solution (if your ISP doesn’t provide you with a static IP)
- Choose a Magic Packet sending solution
- Choose a remote connection solution
Having the ability to remotely access your computer is a good idea because you never know when you may need to get in there.
Most Magic Packets contain security and access controls so that you can safely and securely access your computer and even transfer files if needed.
As with any protocol, you will want to be sure that whatever Magic Packet you choose, it will be compatible with your system. They each have different system requirements.
Being able to access your computer anytime and save energy with Wake on Lan is a no brainer.
When you finish accessing your computer remotely, you can even put it back to sleep to save energy. If you have remote access, you can wake up and put the computer back to sleep as needed. It’s a win-win!
