I have a dual boot system with Windows 7 and Windows 8.

After I shutdown in Windows 7, wake-on-lan works perfect but if I shutdown in Windows 8, it doesn't work. Even if I sleep or hibernate in Windows 8, wake-on-lan works.

Can anyone tell me why is this happening?

I found that it was related to the Fast Startup feature in Windows 8. After I disabled it, it worked fine.

Here is how:

  1. Press the Win + W.

  2. Type change power buttons and press Enter.

    S2

  3. Click Change settings that are currently unavailable.

    S3

  4. Uncheck Turn on fast startup.

    S4

  5. That's it.

This doesn't work for me, Fast startup was already turned on. –  Caleb Jares Oct 28 '12 at 21:31
    
Oh, what does fast startup do? –  Caleb Jares Oct 28 '12 at 21:32
    
Hmm, sounds like something I'd like to keep. Is there any way to have my computer able to wake when I try to remote desktop, but still keep fast startup? –  Caleb Jares Oct 28 '12 at 21:37

Sleep and hibernate will work even with fast startup enabled. –  Zuck Oct 28 '12 at 21:39

This has changeg with the RTM version. Disabling fast startup does not fix Wake-on-LAN. WoL was never supported from Shutdown in any version of Windows. It's only supposed to work from Hibernate and Sleep. It's basically a bug in Windows 7 that still keeps the NIC powered on. Yes there is a hardware state difference between Shutdown and Hibernate. Hibernate does not power off the NICs but Shutdown does. Shutdown just never properly powered off before in previous versions of Windows. –  Locutus Jan 22 '13 at 3:16

"As a result, Wake-On-LAN is only supported from sleep (S3) or hibernate (S4) in Windows 8."

"Remote wake from hybrid shutdown (S4) or classic shutdown (S5) is completely unsupported."
