Does that mean that Wake on LAN is not properly configured? What setting am I missing? Go to Solution. View solution in original post. I bet that works. If not, please indicate in your reply whether the link light remains lit on the NIC when your test PC is turned off.

Did I miss something? Where did Dell document that Deep Sleep has to be disabled? Where did they document that you need to turn off fast start in Windows 8. I got the same problem aswell, two systems running Windows 7 Pro x I am guessing this is related to mailfunction of the bios from dell, because it always turns off the lan port, even in S3. Have never had a problem with prior Optiplex models GX, etcbut these are the first bit Windows 7 machines to go into production the others are running bit Windows XP.

Hope this gets fixed soon!! After quite a bit of trouble-shooting and testing, I have discovered a way to work around the problem:. Once I made the above changes, the Optiplex s now were able to be powered on remotely with the same WOL utilities I use for all of the other Dell computers on our network. In my testing, I started with the latest BIOS version A05 and kept backing off, and A02 was the first version where the above settings worked successfully.

Of course, I would like the ability to update to the latest BIOS, so hopefully Dell will offer an update to fix the issue. Thank you - this worked for me! I was on A04 before, and after trying A05, where it also did not work, I downgraded as per your suggestion.

I immediately noticed that now the network card is on when the PC is in standby mode or power off mode blinkenlights on network card still activeand wake-on-LAN finally works. Note: Although the network adapter stayed on after my first poweroff, wake-on-LAN did not work until I did a complete power cycle boot to Windows, shut-down from Windows.Skip to main content.

You can click to select this check box on the Power Management property page in Device Manager. When a USB device is enabled to wake the computer, the default behavior permits the computer to enter the S1 system power state for standby. Standby is not the S3 system power state. The S1 system power state is a "lighter" system power state than S3. The S1 system power state typically conserves less power than the S3 system power state. More Information.

Updated | Dell is reportedly working to bring back S3 sleep to the XPS 15 9570

Malaysia - English.You can put your computer in any of several different power-saving states, depending on whether you value your time or your electricity bill. Note that S2 sleep mode is often disabled in computers and is accessed only when the computer is unable to go into S3 sleep mode.

You can choose Sleep Standby or Hibernate from the menu that pops up. Resuming a computer from S3 sleep mode normally takes a few seconds, whereas resuming a computer from S4 sleep mode takes a few minutes, so use S3 for shorter sleep intervals and S4 for longer ones. Speed up sleep with S1 sleep mode: If you're looking for an option that will save power and resume even faster than S3 sleep mode does, you can access S1 sleep mode.

Resuming from S1 usually takes less than 2 seconds. To access S1, open your system's BIOS by restarting the computer and pressing the appropriate key during boot-up—typically you'll see a message similar to 'Press Del to enter Setup'.

There you will see an option to change the default suspend mode from S3 to S1. From now on, when you choose Sleep from the Start menu, your computer will go into S1 sleep mode. Just a note for you conservationists out there: S1 sleep mode uses about watts to S3's 5 watts, so it isn't as easy on your electric bill or for laptop users, your battery as S3 is.

Related: PCs Consumer Advice.States S1, S2, S3, and S4 are the sleeping states. A system in one of these states is not performing any computational tasks and appears to be off. Unlike a system in the shutdown state S5however, a sleeping system retains memory state, either in the hardware or on disk.

The operating system need not be rebooted to return the computer to the working state. Some devices can wake the system from a sleeping state when certain events occur, such as an incoming call to a modem. In addition, on some computers, an external indicator tells the user that the system is merely sleeping.

With each successive sleep state, from S1 to S4, more of the computer is shut down. All ACPI-compliant computers shut off their processor clocks at S1 and lose system hardware context at S4 unless a hibernate file is written before shutdownas listed in the sections below. Details of the intermediate sleep states can vary depending on how the manufacturer has designed the machine. For example, on some machines certain chips on the motherboard might lose power at S3, while on others such chips retain power until S4.

Furthermore, some devices might be able to wake the system only from S1 and not from deeper sleep states. Power consumption Less consumption than in S0 and greater than in the other sleep states. Processor clock is off and bus clocks are stopped. Software resumption Control restarts where it left off.

Hardware latency Typically no more than two seconds. System hardware context All context retained and maintained by hardware. System power state S2 is similar to S1 except that the CPU context and contents of the system cache are lost because the processor loses power. State S2 has the following characteristics:. Power consumption Less consumption than in state S1 and greater than in S3. Processor is off. Bus clocks are stopped; some buses might lose power.

Software resumption After wake-up, control starts from the processor's reset vector. Hardware latency Two seconds or more; greater than or equal to the latency for S1. System hardware context CPU context and system cache contents are lost. Power consumption Less consumption than in state S2. Processor is off and some chips on the motherboard also might be off. Software resumption After the wake-up event, control starts from the processor's reset vector. Hardware latency Almost indistinguishable from S2.

System hardware context Only system memory is retained. CPU context, cache contents, and chipset context are lost. System power state S4, the hibernate state, is the lowest-powered sleeping state and has the longest wake-up latency. To reduce power consumption to a minimum, the hardware powers off all devices. Operating system context, however, is maintained in a hibernate file an image of memory that the system writes to disk before entering the S4 state. Upon restart, the loader reads this file and jumps to the system's previous, prehibernation location.Forum Rules.

I called Dell who are now escalating this to their Product Team [? 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. Can't remember if that is deep sleep or not Steve.

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? Originally Posted by newpersn. Also make sure that your computer can't put your network card to sleep when idle. Last edited 16th April at PM. 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 : Code:. I think we have this now. Also where one setting has an effect on another there is often an explanatory note in the BIOS text pane.

States S1, S2, and S3 are all various aspects of the Sleep function. If you are running an incompatible video card, some or all of these states will be unavailable.

S1: the most power-hungry of sleep-modes. All processor caches are flushed, and the CPU s stop executing instructions. S2: The CPU is powered off, this state is rather less found. S3:In this state, RAM is still powered, although it is almost the only component that is.

Since the state of the operating system and all applications, open documents, etc. The computer is faster to resume than to reboot, secondly if any running applications have information this will not be written to the disk, This state is comparatively more common.

S4: In this state, all content of main memory is saved to non-volatile memory such as a hard drive, preserving the state of the operating system, all applications, open documents etc. That means that after coming back from S4, the user can resume work where it was left off in much the same way as with S3. The difference between S4 and S3, apart from the added time of moving the main memory content to disk and back, is that a power loss of a computer in S3 makes it lose all data in main memory.
