Use Wake-on-LAN to turn on your Computer using your Android Phone

Image
Earlier we talked about Wake-on-LAN.  Let us now see how to use your Android device to remotely power on your PC. Following day, you can get to your desk with Windows already booted. Before You Start For this setup to work, your computer must support Wake-on-LAN  (WoL). WoL is a feature of the motherboard.  We've already talked about WoL- how to set it up and use it so we'll directly jump to what we really want to do here. Note: If you cannot find an option for Wake on LAN, the following setup likely won’t work. However, you can still  set Windows up to launch selected programs at boot . The Quick & Easy Setup If your computer system supports WoL, your first step is to install  Wake On Lan , a free Android app. Download:  Wake On Lan (Free) Next, you need to connect your Android device to your Windows computer using the app. When you first open the app, it will look pretty bleak.

What is Wake-on-LAN

How convenient would it be if you could power up or turn on your computer remotely from miles away and that too in a low power mode. Well that's what Wake-on-LAN is all about. Let's check out what exactly is this Wake-on-LAN and how can you enable it. So What is Wake-on-LAN? Wake-on-LAN (sometimes abbreviated WoL) is an industry standard protocol for waking computers up from a very low power mode remotely. The definition of low power mode  has changed a bit over time, but we assume that it means that the computer is OFF  and still has access to a power source. The protocol also allows for a supplementary Wake-on-Wireless-LAN ability as well. This is useful if you plan to access your computer remotely for any reason: it allows you to retain access to your files and programs, while keeping the PC in a low-power state to save electricity. Anyone who uses a program like TeamViewer, or keeps a file server or game server program available, should probably have the op...
