Windows 7 refuses to remain in Sleep mode

Topic

New Reply

Hi,
At night, when shut down my computer, I usually use the function ”sleep”.
However, for an unknown reason, my computer wakes up two or three times every single day, between 6 and 8 P.M.
Does anyone know why this happened, and the solution to this problem?

Thank you in advance for all assistance you could provide.

Jean-Pierre.-

Are there any scheduled tasks at that time? Can the computer be awakened by the network card?

Not that I know of and I have no idea what a network card is, and where to find it to eventually turn it off. Can you help?

You should check the task scheduler to see if you have scheduled tasks at that time.

For the network adapters, you need to open device manager and look for network adapters. If you find them, you can right click each of them, choose properties and then the power management tab. Let me know what is shown there.

Thanks. I checked the properties of the network adapters, power management and I attached an image of what it is.
I checked the Task Manager… I cannot see any scheduled tasks for that time, unless the time is hidden somewhere in the Task Manager, because I cannot see any schedule anywhere.
Please, forgive my ignorance, I am far to be familiar with all those things in my computer; it is the reason why I am posting here, and try not to look too dumb.:rolleyes:

I suggest you check the option to Allow the computer to turn off this device to save power, for both adapters and uncheck the option Allow the device to wake the computer. The latter is the one most relevant to this issue.

I have done as you suggested. The proof will be in the pudding tonight as I put it to sleep. Thank you very much, I should have seen that but anyway, I hope this will fix the problem once a for all.
I cannot thank you enough for this was upsetting my evenings watching television.:)

I hope it solves it, but it may not. I know my network card was the culprit in a similar situation with my laptop, so I am hoping that may be the case with you too :).

If you lose internet access after you awake from sleep, uncheck the Allow the computer to turn off this device to save power option but leave the Allow the device to wake the computer option unchecked as well.

A lot of laptops have Sleep and/or Hibernate issues if you set the Allow the computer to turn off this device to save power option.

Thank you, I do not have a laptop, I have a desktop.

It will take a few steps to drill down to this setting, but it is worth a try:
control panel
system
performance information and tools
adjust power settings
change when the computer sleeps
change advanced power settings
in the list, open up: sleep
then open up: allow wake timers
make sure the setting is: disable

Thank you 2 Star Lounger, I did exactly as you wrote; I had not too much trouble to find out where to go, but your explanations were easy to follow and I turned the settings to”disable” as suggested.
I hope it will work, and will soon find out tonight.
Thank you very much for offering this solution to the problem.

Hi Jean-Pierre,

I’ll add my tuppence worth in as well.

I think Rui hit the nail on the head with post #2 especially with are there any tasks scheduled for that time.

I’ve also had problems with network cards but they would wake up the PC instantly, not to a schedule.

I think that ldb’s solution above may work but it doesn’t reveal the underlying problem, ie what is trying to run at that time!

There is a way to find out though, from a command prompt enter “powercfg -lastwake” sans quotes and that will tell you what woke the computer up.

In the screenshot above I have a scheduled task called Wakeup!

Thanks Browni, I entered it in the command/run, without quotes as suggested, (powercfg -lastwake) and I don’t have any results showing, nothing, not even the response (black window) as shown in your example. I have no idea why nothing comes up. I tried several time, nothing comes up. Thanks for your help.

Apologies Jean-Pierre, the easiest way to get to the window I mentioned is to press the windows key, then type “CMD” without quotes and then press the enter key.

Then you can type in the “powercfg -lastwake” command and it won’t disappear.

I’ve been trying to find/fix a laptop that wakes immediately after sleeping. (I’m pretty sure at this point I will have to restore the system from an “image” backup) Here are some things I tried which may or may not help your problem:

– open a “Command Prompt” (click Start Button and type it into the Search box to find it)
Type “powercfg -lastwake” to find out what the last thing that woke up your computer was. Do this after it starts by itself but not after YOU restart it normally.
Then type “powercfg -devicequery wake_armed” to find out WHAT devices can wake your computer. Inspect the list of devices for a Network device (Modem, Ethernet, etc.) or wireless mouse. You can disable/uncheck this in the Device Manager under the device Power Management settings.
There are other powercfg command switches – to see them type “powercfg /? |more” at the Command Prompt.

– Did you computer appears to run anything when it started? Open “Task Scheduler” The list of tasks run in the last 24 hours never seens to list anything on my computer. Scroll down to the Active tasks list and look for anything set to start when you are having trouble. You can edit any task to disable the option that allows it to wake up your computer to run under the Conditions tab. Double-click the task to open its window, then click on “Properties” in the actions pane to edit it.

– in “Device Manager” uncheck “Allow this device to wake up the computer” on BOTH mouse + keyboard. Unchecking one does not resolve issue.
– in “Device Manager” turn off all device options that turn off devices to save power (keep notes so you can restore these if they don’t help) Usually USB and network devices use this setting.

– Microsoft troubleshooter http://windows.microsoft.com/en-US/windows-vista/Troubleshoot-power-problems

– in BIOS Power Management (see manual for key to hit at startup) in Power Management settings disable power on from PCI devices & from LAN

– if you suspect a device someone recommend starting up in safe mode, run “Device Manager”, disable all the drivers individually, but not the processer. Enable them one at a time, rebooting each time. Maybe unplugging all external devices would be a simpler test.
– Power sleep options:
Open the Control Panel and select Power Options
Click on Change plan settings under your power plan.
Click on Change advanced power settings.
Click on Change settings that are currently unavailable (allows Power Options that are grayed out to work.)
Recommended Settings for Sleep
Hard disk Set to at least 1 minute before the computer
(Sleep after setting below) is set to sleep.
Sleep Sleep after This is for the computer.
Set to at least 1 minute after Hard disk/Display turn off.
Sleep Allow hybrid sleep Set to Off.
Sleep Hibernate after Set to Never.
USB settings USB selective suspend setting Set to Disabled.
Power buttons and lid Start menu power button Set to Sleep.
PCI Express Link State Power Management Set to Off.
Display Turn off display after Set to at least 1 minute before the computer
is set to sleep. Usually same as the Hard drive.
Multimedia settings When sharing media Set to Allow the computer to sleep.

If you read all the way down here I hope you aren’t discouraged. Your problem sound fixable.

I had this problem in a daytime situation. My computer would return from sleep without my wanting it to. The answer proved to be due to the computer (mouse?) detecting vibrations as I walked across the floor! That was enough to trigger the awaking! I doubt that this is the answer to your specific problem, but it illustrates how diverse the solutions to a problem can be.

Thank you, I have followed your tip and I got a result as ”0”
It seems the problem is elsewhere, but thanks for that, it was worth trying.

Are you sharing files, music, videos or printers from this computer? If so, Win 7 won’t let the computer stay asleep…

Reply | Quote

Quick answer: NO. Nothing is shared and the computer is the only computer on the wireless network. If I disconnect the computer from the network, and then reconnect, the reconnection occurs within a second or so. It is only when the computer is returned from sleep mode that the 50+ second delay occurs.

Thank you PAtDrummond. the problem has already been fixed by some members of this Lounge. Thanks anyway, I keep this as a reference, just in case.
