WOL and Dell Optiplex 740

Filed under: Client Management — Tags: , , , — Michael @ 09:48

This is kinda “WTF?”. I wanted to use Wake-On-LAN (WOL) with our Dell Optiplex 740 workstations. By default, WOL wasn’t enabled in BIOS, so I set the two relevant options by disabling the low power mode and enabling the wake-up option of the NIC. After some testing with Dameware’s WOL function (which didn’t work) and some other tools (wol, winwol, wolcmd also didn’t work) I finally woke up my testclient successful out of hibernate with Magic Packet Sender. Also WOL worked out of standby mode. But only with Magic Packet Sender, although I configured other tools to use port 9 UDP too (can anyone explain me that?). At last I tried to wakeup the PC from poweroff. I got frustrated – it didn’t work. Hibernate and standby was never a problem, poweroff = no reaction. I called the Dell business support, but unfortunately they also had no clue. After some googleing I found this forum link, where other users report similar problems with other workstation models. Up to now Dell did not respond to their posts…


Okay, the Dell support guy I talked to has also no solution. In the meantime I discovered that all our Dell workstations (also the Precision T3400 and older Optiplex) don’t wake up from poweroff. Seems that I’ve to investigate… I will post updates here.



  1. I’ve been trying to get this to work all day and it’s driving me nuts ! I wrote a whole tool for everyone in the company to remotely wake their machine when they need to so we could save a huge amount of power (60 optiplex machines running day and night) I’ve tried:

    magic packet sender

    but I can’t get these MF’s to boot … have you found a way in the mean time ?

    • No, obviously not. It seems that no one cares at Dell… Do you have exactly the same issues with WOL working out of standby/hibernate but not out of poweroff?

      • No, I can’t even get it to work out of standby/hibernate, even with the Magic Packet Sender tool you described. I’m gonna call the Dell support desk now also to explain the problem …

    • Okay. Please tell me if you get any solution for this. I’d really appreciate it 🙂

  2. ok, Dell told me that the WOL option isn’t a supported feature, and they can’t help what so ever, even though they’d like to 😦 I asked them to escalate this to the engineering teams and they said they didn’t know how to do that ! What kind of company is this ? I guess we’re on a dead trail here 😦

  3. WTF? Which Optiplex model do you have? The support guy I talked to said that WOL always worked and many other customers use it without any problems.
