Wake on Lan in Dell Inspiron 7720

Hi pw,

Welcome to the community.

I would like to inform you that wake up on lan option is enabled by default on your system. If you wish to boot the system using network please follow the steps below:

Keep tapping F2 key on the keyboard while starting the system at Dell logo.

It will take us to a different screen called BIOS.

Select Boot in the menu. And press + to make Network as the first boot device.

Press F10 to save and exit.

Please perform these steps and let us know the results of the same.

Thanks and Regards

Hi Sandeep,

Thanks for quick support. Haven't you mistaken network-boot with wake-on-lan? How should I turn the laptop remotely on after setting this option in bios?

Ok, thanks, I tried it yesterday (I had the advanced settings on, not sure about power managment settings), but the laptop failed to start .Could you please write what parameters should be used to wake the laptop? I pasted MAC address, and I don't know what IP should I use since I get it from DHCP from my router. I use the one I got after booting windows. What protocol and port should I use? UDP \ 9 ?

Hi Witosso,

You might need to create a static IP address first in order to setup Wake on LAN.

Our scope of support on same would be limited. However, I have researched on this issue for you and found a tutorial which would be helpful for you in setting up Wake on LAN:

Hi Sandeep,

Once again - thanks for help - I've tested your settings - the computer is waked up, when I put it to sleep (in this case Wake on Lan works). But when I turn it off or hibernate it, it doesn't - so motherboard probably doesn't support Wake On Lan, am I right?

Hi Witosso,

Wake on LAN would only work if the network card is getting power while it has been put to hibernate or shutdown. It might not be supported by your network card.

However, I have find out one of the article relating to this:

"This depends somewhat on your internal settings and the way your machine is designed to work. It doesn't "wake" because your NIC doesn't accept packets in standby or hibernation mode. (Of course, you must have a suitable NIC with the WOL feature.)

You can check by looking at the LEDs on your NIC when the computer is turned off and when it is in "sleep" mode. If they are lit, the computer should wake when the remote packet is received. When the computer is hibernating if the LED isn't on it will not wake.

You can explore the settings in the "power" section of a Windows computer Control Panel, but this may not be adjustable."

I hope I was able to answer your query today.

Thanks and Regards

Hi Sandeep,

yes I was aware of that. The Inspiron 7720 17R SE doesn't have any NIC LEDs, so I'm not able to check whether the LAN interface is on. Does Inspiron 7720 motherboard support wake on lan?

Hi Sandeep,

You're not right, there are some PCs where WoL can power up the computer - but motherboard and Network card must support it. In that case the Network Card is not fully powered off but listens for the Magic Packet. Dell Inspiron 7720 17R seems not support it indeed. Thanks for help

Hi Witosso,

I believe there was some confusion as I meant that this system would not wake up on LAN as network card doesn't support the same.

If the network card and motherboard of system supports then it can definitely wake up from hibernate and shutdown as well. However, network card of this system doesn't support the same.

I hope I was able to answer your query today.

Hi,

Did you find the answer? I have the same problem with another Dell model.

Thanks
