Dell Optiplex 9020 Do Not Wake On LAN

[6Foot2]

We have quite a few of these now and so we wanted to enable WOL for all of them to have them ready for users when they come in [Deploy any new packages and complete any waiting updates etc]

 

We found that none of the 9020s would WOL. I have updated the BIOs from A02 to A10 and checked the BIOS settings again [Power management: WOL: LAN only, Deep sleep control: Disabled]

 

The BIOS upgrade did not resolve the issue. I called Dell who are now escalating this to their Product Team [?]

 

Waiting for more news...

We have some old intel based fujitsu PC's with this problem. Turned out to be a setting in the LAN in windows. I didnt believe it at first until I saw it with my own eyes. I think it was to do with power but cant remember exactly.

Did you change the power state from S5 to S3 thingy within the BIOS? (Can't remember if that is deep sleep or not)

That^

 

I've the same issue with Fujutsu and RM machines. Had to install the intel LAN driver and facility then manually configure it on each machine. Was quite a tax and I was annoyed I couldn't do it from BIOS, but it worked!

I have just been to have a look at one of the classroom machines to check the network card settings in Windows:

I should have thought that these settings would be OK?

 

Looking at if there are any updated Intel drivers now...

Allow only a magic packet to wake the computer need to be ticked.

We had a similar issue with some of our HP desktop models with Intel network adapters where by WOL stopped working the moment I updated the drivers to ones from the Intel website, but fixed again once I reverted to drivers available from Windows Update.

 

I guess there's a setting (hidden?) somewhere either in Intel's driver settings or in their management software but I was too lazy to find this out as since the windows update drivers worked fine, there wasn't any point.

I'm not sure but System Idle Power Saver and/or Energy Efficient Ethernet look like they might also want turning off to see if they have an effect

I will give that a go. No newer Intel drivers available.

You may need to Disable ErP/EuP in the BIOS if there is such an option.

[RJohnson91]

We have these computers also, to get WOL to work we have changed the following in the bios;

 

Under power management:

 

Deep Sleep Control - Disabled

Wake on LAN - Set to LAN

Block sleep - Block Sleep on S3 state

 

That's what we did to enable WOL, we found by default that all magic packets were allowed through.

 

Also make sure that your computer can't put your network card to sleep when idle.

We had a problem with PCs with integrated Intel NICs. They all had WOL enabled in the BIOS and in the driver but they still wouldn't wake. In the end, the setting that we needed to enable was one called Enable PME. I can't remember exactly where the setting is set but I still have the registry fragment which we're pushing out with a GPP:

 

Hive                 HKEY_LOCAL_MACHINE 
Key path             SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002BE10318}\0007 
Value name           EnablePME 
Value type           REG_SZ 
Value data           1 

 

Setting that and rebooting the machine a couple of times fixed the problem for us.

I think we have this now. The answer was to enable WOL but also disable Deep Sleep and Block Sleep [both in Power Management]

 

In other BIOSes we only had to enable WOL to make this work. Also where one setting has an effect on another there is often an explanatory note in the BIOS text pane.

 

Thanks everyone.
