What’s the first thing you do when you get to your desk? Probably turn on your computer. Whether you tap your keyboard, move your mouse, or press the power button, you have to be at your computer before you can start it. Wouldn’t it be nice if your computer was ready to go?

Let us show you how to use your Android device to remotely power on your PC. Tomorrow, 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. The easiest way to find out whether your computer supports WoL is to boot into the BIOS How To Enter The BIOS On Your Computer How To Enter The BIOS On Your Computer Inside the BIOS you can change basic computer settings, like the boot order. The exact key you need to strike depends on your hardware. We have compiled a list of strategies & keys to enter... Read More and check the power management settings. Press the correct key at boot (try ESC, DEL, F2, or F8), and your computer should enter the BIOS.

Once you’re inside the BIOS, look for the Wake On LAN setting and enable it. You’re likely to find this along with other settings related to power management or networking. BIOS options vary from computer to computer, so you might have to do some digging of your own.

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 4 Boring Tasks You Can Automate With the Windows Task Scheduler 4 Boring Tasks You Can Automate With the Windows Task Scheduler Your time is too valuable to be wasted with repetitive tasks. Let us show you how to automate and schedule tasks. We have a few great examples, too. Read More .

The Quick & Easy Setup

If your PC does support WoL, your first step is to install Wake On Lan, a free Android app.

Next, we need to connect your Android device to your Windows computer using the app.

When you first open the app, it will look pretty bleak. Tap the + icon in the bottom right and follow the on-screen instructions to add your first device.

Once you follow the app’s instructions, it will search for devices connected to your local network. If many computers, phones, and tablets use your internet connection, the list can be confusing. The easiest way to identify your target computer is through its MAC address How to Look Up the MAC Address on Your Windows PC How to Look Up the MAC Address on Your Windows PC The MAC address is a unique identifier for each piece of hardware connected to your home network. We show you how you can find your MAC addresses and how to potentially change them. Read More .

To find your computer’s MAC address, head over to your computer, press Windows key + R, enter CMD, and hit Enter. Then type ipconfig/all into the command prompt and press Enter. This command will reveal your computer’s Physical Address, a string of six two-digit numbers, also known as the MAC address.

Now return to the app and select the entry with the matching MAC address. Choose a nickname for the device and choose the appropriate Wi-Fi network.

Once you’ve added your computer to the app, it’s time to see if it works! Place your computer in Sleep or Hibernate mode (Start > Power > Sleep / Hibernate), and press the Wake button on the Wake On Lan app.

If it works, great! If not, you have two more settings to check.

The Nitty Gritty Setup

So, you’ve enabled WoL in the BIOS and set up the app as described above, and it still didn’t wake your computer? Try the following settings.

Enable WoL for Your Network Adapter

You probably haven’t set up your network adapter to accept a Wake-On-LAN packet.

In Windows 10, right-click the Start button and select Device Manager. You can also do a Windows Search for Device Manager. Navigate to Network Adapters, right-click the one you use to connect with the internet, and select Properties.

On the Power Management tab, you’ll find three checkboxes, including Allow this device to wake the computer and Only allow a magic packet to wake the computer. If they’re not already checked, do so. This should clear up any trouble that’s causing the Android app to malfunction.

Disable Fast Startup

WoL only works when you’re trying to wake the computer from Sleep or Hibernation How to Fix Windows 10 Sleep Mode Issues How to Fix Windows 10 Sleep Mode Issues Is something interfering with your PC's sleep pattern? We'll show you how to troubleshoot sleep mode settings. These solutions are more effective than counting sheep. Read More . WoL doesn’t work with the default hybrid shutdown in Windows 8 and Windows 10. The simple solution is to turn off fast startup.

Open the Control Panel, search for Power Options, and select Change what the power buttons do. At the top, click Change settings that are currently unavailable, then scroll down and uncheck Turn on fast startup (recommended). Finally, click Save changes .

Now put your computer to Sleep (Start > Power > Sleep) and try this again. Is it finally working?

Wake Windows

Once you have set up the Wake On Lan app, you can start your computer with the tap of a button.

Unfortunately, this app won’t let you wake your computer automatically; for example, waking your computer based on a schedule or as your phone makes a connection with your Wi-Fi network. For the latter, try PCAutoWaker, though note that the app hasn’t been updated since 2011.

    The easiest way to see if your device supports it is to 1)install the two apps and configure it all and see if it works or 2)research all the variables that are going to drive you crazy when it doesn't just work right off the bat. Your laptop is one of a thousand different models from one manufacturer, and each manufacturer has their own ideas of which features they think need to be available, with different motherboards, network adapters and BIOS versions. Each BIOS can have several revisions even in the same year they were installed on the same model laptop, where they can choose to enable or disable features to solve problems when different manufacturers ask for fixes to make their specific laptops work as desired. Long story short, I have been down this road many, many times only to find that a specific chipset on my particular motherboard of my machine says that it supports a feature but actually it doesn't work. whether you turn it on or not, if they disabled it for some specific reason when the machine was released, they may not even have documented that it was disabled! Even then, windows may trick you by letting you turn on a switch or checkbox but the hardware ignores it for the same reason mentioned before. Furthermore, your router may not support the features needed for WoLAN or WoWLAN (Wake on Wireless LAN). DLink routers are really bad for that.
    In the end, if it doesn't work without too much fiddling with settings, drop it and try to find another solution so you don't waste weeks trying to figure out every switch and option and hardware update that should make it work. You may only discover after it's way too late that someone else went through the exact same steps and then paid to have advanced support from a hardware manufacturer tell them 'That option isn't available on the chipset you have on that board, and you can't update it'. Been there too.
    "Support for Wake on Wireless LAN in Windows 7 drivers is optional and some drivers might not support this functionality. If you follow the process and the option to enable this is still grayed out, then your driver does not support this functionality. Follow up with your hardware manufacturer for support information." https://technet.microsoft.com/en-us/library/ee851581(v=ws.10).aspx

    you do know what LAN means dont you? Local Area Network.... that encompasses Wifi, Wifi is just wireless interlinking of digital devices.. once a certain device is connected to a wifi, its also known to be connected as part of your LAN aka Local.Area.Network.

    read up on technology kid, dont comment on shit before you know your shit. (and no, i didnt say before you know you're shit).

    Wake on WLAN is indeed possible with some devices. Your wireless network adapter must support it.

    Hi
    thanks for the solution
    I did it even without hibernate or stand by and from a fully shut down computer but I have a problem...
    When I tap the wake icon system starts and my windows boots up but windows connection to my router doesn't connect and I cant access network.
    I have to restart the router and then it works perfectly , any ideas?

    Many clone-/white-box after market based system builds support this. All business PCs have it.  Not many consumer PCs do. Laptops can have it, but the Wake On LAN feature MEANS Wake On *LAN* not Wifi as the Ethernet port is typically the only one that knows what to do with the magic packet. As for power to the supply itself - get off the switched outlet strip.

      What the *** are you talking about... LAN and ethernet are not the same thing. "PCEvilGenius" loool

        He's not completely off.

        Ethernet is the most common networking protocol used on LANs. And while you can set up a LAN via WiFi (I read), he's right that the average WiFi adapter can't handle a magic Wake-on-LAN packet; this requires a wired LAN / Ethernet connection.

        Yes, Ethernet and LAN are not the same, but an Ethernet cable is a type of LAN cable. And most Windows PCs and laptops only have an Ethernet port, i.e. that's the only way to connect them to the LAN.

        Please correct me if I'm wrong and explain how it's right. Much appreciated!

      I think that some computers support wake via WiFi. Snoop around your BIOS settings to see if there's anything there. I must admit it's unlikely on a laptop, since they often have a limited BIOS, but maybe you'll luck out.
