Need to disable hibernation ( or enable Wake On Lan/ pattern ) for backup routine.


Computer does not respond to WOL or any type of network requests. Also, hibernates regardless of NIC or power settings.


Model: Dell Opti 780
NIC: 82567LM-3 Intel

What I've Tried

  • Wake On LAN and Wake On Pattern enabled in NIC configuration.
  • Low Power Mode disabled and Remote Wake Up enabled in BIOS
  • High-Performance power scheme with everything set to "never".
  • powercfg.exe /hibernate off. Also, -h off
  • Sleep set to never.

There used to be a simple, easy to find checkmark in XP that said 'enable hibernation'. One could uncheck it and be done with hibernation. Apparently, someone in Redmond ( or maybe at Intel ) disliked the ease-of-use factor of this idea and decided to make it pure hell to disable hibernation or enable WOL in Win 7.

WoL has very little to do with Windows and a lot to do with your BIOS/NIC settings. –  squircle Apr 27 '11 at 21:38
Low Power Mode needs to be off for WoL, IIRC. –  afrazier Apr 27 '11 at 23:46
I agree with that. I have set the NIC and BIOS settings for WOL but maybe Sane ( below ) is on to something. No hibernation will solve this as well. The hibernation settings are more obscured and klutzy in 7. –  Bubnoff Apr 28 '11 at 0:12
@afrazier -- I did that. Still no luck. –  Bubnoff Apr 28 '11 at 0:14

  • Is there a Layer-3 switch between the client computer and the computer sending the WoL packet? If you have a layer-3 switch then look into setting it up to pass magic packets.

  • Are you using the correct WoL tool for your NIC? Some NIC vendors use a differently formatted magic packet then other vendors.

Those are both good possibilities. I think at this point -- disabling hibernation is the easiest solution. I think I may have overlooked a setting somewhere. –  Bubnoff Apr 27 '11 at 23:54

Type "edit power plan" into your Start menu. When you're in the Edit Plan Settings window click on Change advanced power options and you can find this:

Have done this. 'Hibernate after' is not there in this stations sleep settings. Could be because I've run the powercfg.exe /hibernate off? –  Bubnoff Apr 28 '11 at 1:27
Yes, that's why. Missed that you already tried this. –  Louis Apr 28 '11 at 1:55
