Solved PC wakes immediately from sleep...

[rezelute]

Hi,
I have spent alot of time trying to figure this out and so far i have got no where. When i set my computer to sleep (Windows 7 64bit) the monitor goes into standby mode and then as soon as my computer is about to sleep it wakes up immediately. I have unchecked (Device manager) the adapter card, unchecked the mouse and then unchecked the keyboard from waking up my PC and it still refuses to sleep. When i type the command to find out what is waking my PC in cmd (-lastwake) i find that a USB root controller standard is waking the PC up but in the driver devices the USB roots are are unchecked to wake my PC. Im at a complete loss here, i have no idea whats going on. I thought it might be my Bios waking up the computer as soon as it detects sleep mode but i dont see anything in BIOS to prevent this so i think its a Windows issue.

Anyone have any suggestions or ideas?

Do you have a usb mouse plugged into your front usb ports?

 

[rezelute]

No, there is nothing using the front USB ports. I have 3 USB devies in total: Keyboard, wireless mouse, and wired mouse. However i have tried disabling each (by removing the wires) and still no luck.

Check your bios for a wake-on option. maybe located in the power management menu.

Hello Rezelute,

You might check through the options in the tutoral below to help see what may be waking up your computer. The STEP SIX section is the most common reason though.

Hope this helps,

Thank you Brink, I will go through each of the steps 1 at a time when i get back home and post update back to help anyone else.

I think i might have found the solution to this sleep problem that might help others (havent tested yet but im fairly sure its the culprit): I have an ASUS P5Q SE plus and reading the manual there is something i may have misunderstood, it says under the section USB DEVICE WAKEUP:
"The USB wakeup requires a power supply that can provide 500ma on the +5VSB lead for each USB port..." And then it shows the default jumpers set to +5V (i.e. jumpers on 1 and 2) and not +5VSB (i.e. jumpers on 2 and 3).

I think this maybe the problem since it does look like there is something external other than Windows controlling the sleep function. I am going to test tomorrow morning after i switch the computer off for the night and post back if im right - I will also post back if im wrong so it goes on failblog

Just a thought... But some time ago I had a computer that simply would not go to sleep for more than 5 seconds at a time. It took a while to find the problem but it was in the Bios... I had enabled the "Wake on Display Activity" function (Asus M2n series)... when the monitor went into standby it was waking the computer back up.

Over time I've taken a policy where I only enable the Bios level wakeup features for the keyboard and mouse. Everything else is off.

Thanks but i have no such function on my BIOS, i will test the jumper setting soon i think, im just abit lazy at the minute because changing jumper settings means that i have to remove so many components after ive just setup my new PC .

Ahh... ok... lets hope you get it fixed.

Another cause of this problem could be the Computer Browser service, which is responsible for showing you the computers in your Network folder. If you have a home or business network running, with the Computer Browser enabled in more than one machine, they will hold an "election" in which the most capable machine (based largely upon OS versions) is elected to be the browser master. When your machine is browser master it won't sleep until the rest of the network is asleep. That is, it will be the last machine to go to standby mode.

Although you probably want this running if you're running a lan, you could try temporarily disabling the service and see what happens... especially on laptops as they are almost never elected to be the browser master.

Actually there only needs to be one machine running the computer browser service on a given node, since it will provide an up to date DNS list to all machines on the node.

Ive found the solution to the problem and thought i would post it back here to share with all. Anyone with a later model of an ASUS motherboard will find that this is the answer:

It is as i expected above, the BIOS was forcing the computer to wake back up because the USB device wakeup jumpers were set to "1-2" instead of "2-3" which basically means that there was no power going to the USB Device Wakeup for the computer to sleep hence why it keeps waking the computer up.
To clarify further to any readers, there is an S1 sleep function and an S3, S1 puts the computer in a low power state with tasks still running though whereas S3 is a complete sleep i.e. no tasks running. When you set the jumpers on the USB device wakeup to "2-3" then you are enabling the S3 mode which is what you want .

Very good... as an ASUS owner myself, I appreciate the info!

No problem , i carefully read through the manual again and i was like ohhhhhh i think i get it now lol.
Just bare in mind that on an ASUS there are 3 jumpers you might want to consider replacing:
1- Keyboard wakeup jumper (Not 100% sure but i think they mean PS2 by this)
2- USB device wakeup jumper (which is right next to the keyboard jumper)
3- USB device wakeup jumper (which is next to the actual USBs)

I believe that "2" will make the rear USB ports wake up the computer and "3" will make the front USB ports wakeup the computer.

Whether i only needed to change the jumpers on "2" only i dont know i couldnt be arsed to test it since its hard to change the jumpers without needle nose plyers . I just replaced all 3 jumpers to give them power supply.

I'm pretty sure the jumper layouts are different for each board, but you did prompt me to look at my own MB Manual and switch the jumpers over.

The behavioral change is interesting... on the 2-3 pins the USB device no longer wakes the system up, but they are recognized instantly when I wiggle the mouse... In the 1-2 positions plugging in a thumb drive would wake the computer but it would take sometimes half a minute to figure out what I did to it...

Yes the keyboard jumper thing refers to PS2 keyboard and mouse... and on my MB there is also a BIOS setting that overrides the jumper setting...

And I will say, I like the S3 standby a lot better... the computer is completely silent, no fans running... My room is sooooo peaceful... well until somebody does something on the lan that wakes it up...

Yeh i find it very strange that ASUS didnt consider people would want to use the S3 as a default, perhaps they just wanted to make sure that when users wanted to use the feature they knew what they were doing to supply it enough power to use the function (because says in the manual it needs a specific source of power to work) - but yet again what power supply wouldnt be able to supply that hehe.

Much like Windows itself, motherboards are generally supplied in a "most likely to work" configuration. When they make them they might assume Windows but they don't actually know for certain what OS will be installed, so they have to make sure they'll boot almost anything. S1 is pretty safe as a default... as are the Auto settings for most everything...

I think it's pretty fair to say that most users (as opposed to the clan here) never look in their BIOS and most install and run their software entirely on defaults. So things have to be in a "most likely to work" state or the whole thing comes crashing down.

Looking at the specs for my power supply... the 5volt standby supply only delivers 2 amps... enough for three ports and the motherboard itself.

rezelute's solution worked for me!
Asus P4p800-E mb.
Thank you rezelute! I have been chasing this one for YEARS and have tried probably every "solution" that has ever been posted online!

More info

I realize it has been awhile, but would anyone mind posting a step by step on how to physically apply the solution listed above? I built my own computer but for the life of me don't remember see different jumper settings on my Asus motherboard. My computer goes to sleep, then kicks right back on. It's very frustrating.

Thanks!

Hello Blausser, and welcome to Seven Forums.

I'm not sure about that method, but I would start off checking to see what the wake source was below, and then we can go from there.

follow up

Good morning

a screenshot of the wake log is attached, it's the same all the way down...
thank you in advance for all the help, I'm ready to throw this thing out and start over. It's very tempermental, my last ASUS was awesome.
