Power Options and Sleep Mode Problems

How to Troubleshoot a Vista or Windows 7 Sleep Mode Problem​

   Information

This will show you some steps to help you troubleshoot and find out what is causing your sleep mode problem. These are the usual reasons for sleep mode problems. For more information, see: Windows Help and How-to: Turn Off a Computer FAQs

   Note

• When your computer is in hibernation, the only way to wake it is to tap the case power button.
• If this sleep mode problem just started recently, then you might consider doing a System Restore before or after trying the steps below if they do not help.

Common Problems:

• Computer will wake up for no reason.
• Sleep mode does not work any more.
• Hibernate option is not available in Power Options, then you accidentally deleted the Hibernation file Cleaner in Disk Cleanup.
• Screen saver not working.

   Tip

BEFORE STARTING:Make sure you have the latest device drivers and BIOS installed for your motherboard.NOTE: A out-of-date video driver or other drivers are sometimes the source of sleep mode problems. It is best to keep these up to date to resolve issues found with them.

STEP 1

Check Your Mouse and Keyboard

NOTE: A wireless mouse and keyboard can cause your computer to wake up for no apparent reason, and to not wake up from sleep mode when you press a key or move the mouse. This may also cause your screen saver to not work to. If the computer is using an optical mouse, changes in light can cause the computer to wake.

For a USB Mouse or Keyboard:​

1. Check the BIOS settings to make sure that you have a Legacy USB option enabled.​

​

For a Wireless Mouse or Keyboard:​

​

1. Unplug the receiver on the back of the computer and test.​

​

2. If sleep or hibernation works now, then try:​

A) Download new drivers for you wireless mouse and test again with the receiver plugged in.​

NOTE: Always get your drivers from the source, never from Windows Updates. They do not work properly sometimes.​

​

B) Disable the wireless mouse and/or keyboard wake up option in Step Five below. If you have to disable both of them, then you can wake the computer up by pressing the power button on the case.​

​

C) Time to get a new mouse and/or keyboard that is compatible with Vista.​

​

For a Optical Mouse:​

1. Try not to have direct bright light shining on the sensor or moving around it.​

​

STEP 2

Check Advanced Power Plan Settings

NOTE: Power settings control the computer’s ability to go into and come out of sleep/standby mode.

​

1. Open the Control Panel. (Classic View)​

​

2. Click on the Power Options icon.​

​

3. Click on the Change plan settings link under your power plan. (See screenshot below)​

​

​

4. Click on Change advanced power settings. (See screenshot below)​

​

​

5. Click on Change settings that are currently unavailable. (See screenshots below step 10)​

NOTE: This will allow any Power Options that are grayed out to now work and not be grayed out.​

​

6. Recommended Settings for Sleep​

NOTE: Sleep saves any open documents and programs to memory only, and then puts the computer into a low-power state.​

WARNING: If you lose power to the computer, you will also lose what is in memory.​

​

​

9. Click on OK to apply​

​

10. Just exit out the other windows.​

​

​

11. Test sleep mode. If it is still not working correctly, then continue to the next step.​

​

STEP 3

Check Sleep State Settings in BIOS

NOTE: Make sure you have the latest Video drivers and BIOS for your motherboard. Read your motherboard manual to see if you have any jumpers or settings that sets different sleep voltages for USB.

​

1. Open the Start Menu.​

​

2. In white line (Start Search) area, type cmd and press Enter.​

​

3. In command prompt, type powercfg -a and press Enter. (See screenshot below)​

NOTE: This will give you a report of the available sleep states for your computer and will attempt to report reasons why sleep states are unavailable. You will want to see if the ACPI S1 and/or S3 is listed. ​

​

​

4. Restart the computer into the BIOS settings, and go into the Power Management section in the BIOS.​

NOTE: Usually you will press the F2 or Delete key as soon as your computer starts booting to enter the BIOS. ​

​

5. Make sure ACPI mode: S3 or S1 is enabled.​

WARNING: S1 (Sleep) and S3 (Hybrid deeper sleep). If you are running an incompatible video card, some or all of these states below may be unavailable. If one of the settings causes your computer to not wake back up afterwards, then reset the CMOS on the motherboard and restart the computer, or unplug the computer for a moment and plug it back in, and reset the BIOS back to the factory default settings.​

​

​

​

6. Make sure Wake on Ring and Wake on Lan are disabled.​

NOTE: This will help keep the computer from waking up on its own.​

​

7. Save the BIOS setting changes and exit to restart the computer.​

​

8. Test sleep mode. If this does not help, then move on to the next step.​

​

STEP 4

To See what had Waken Up Windows Last

NOTE: This will give you a list of items that woke up the computer last that may help narrow down what is waking up the computer.

​

1. Open the Start Menu.​

​

2. In white line (Start Search) area, type cmd and press Enter.​

​

3. In command prompt, type powercfg lastwake and press Enter. (See screenshot below)​

NOTE: Notice that I had USB\ROOT\HUB listed. For me, this would be the USB wireless mouse. Your list results will vary of course.​

​

​

STEP 5

To List, Enable, or Disable Device Names Currently Configured to Wake Up the System From any Sleep State

NOTE: This will show you a list of devices that are able to wake up your computer to help you narrow down a device that may be responsible for waking up your computer. It does not mean that these devices are the ones that woke up your computer though, just that they are able to.

​

1. Open an elevated command prompt.​

​

2. To List Devices that Can Wake Up the Computer​

A) In the command prompt, copy and paste in bold: (See screenshot below)​

powercfg -devicequery wake_armed and press Enter.​

​

​

B) Go through the list of devices to see if you have one you do not want to wake up your system.​

EX: A Network Device (Modem, Ethernet, etc.) or Wireless Mouse.​

​

C) If you found a device that may be causing the problem, then check with the STEP SIX section below first to see if you can disable a wake up option for the device in it's Power Management settings in Device Manager to test to see if that is it before proceding.​

​

3. To Disable a Listed Device From Waking Up the Computer​

NOTE: Only do this step if you cannot do it from STEP SIX below using Device Manager instead.​

A) In the elevated command prompt, type below in bold and press Enter.​

WARNING: Be sure to write this device name down in case you want to be able to enable it again in step 4. Once you disable it, it will not be listed again in step 2A until enabled again.​

powercfg -devicedisablewake "exact name of device listed in step 2A"​

​

NOTE: For example, if I wanted to disable the listed (step 2A) High Definition device (HDAC), then I would type powercfg -devicedisablewake "High Definition Audio Controller" and press enter.​

​

4. To Enable a Listed Device Again to Waking Up the Computer​

NOTE: Only do this step if you cannot do it from STEP SIX below using Device Manager instead, or you have done step 3 above with the device.​

A) In the elevated command prompt, type below in bold and press Enter.​

powercfg -deviceenablewake "exact name of device listed in step 2A"​

​

NOTE: For example, if I wanted to reenable the High Definition device (HDAC) that was disable and removed from the list in step 3, then I would type powercfg -deviceenablewake "High Definition Audio Controller" and press enter.​

​

​

5. When done, close the elevated command prompt, and test sleep mode.​

​

STEP 6

To Disable or Enable the "Allow this device to wake the computer" Option for a Device

   Note

• Check your Network device. Network activity can cause the network hardware to wake the computer, especially when the network is always on (like cable and DSL connections).
• High Definition Audio, if listed in STEP FIVE, may also rarely cause the computer to wake from sleep mode. You can disable (only option available) the device as a test in Device Manager to see before putting the computer to sleep. Just enable it again if it is not the problem.

1. Open the Control Panel. (Classic View)​

​

2. Click on the Device Manager icon.​

NOTE: You need to be in a Administrator account.​

​

3. Click on Continue in the UAC prompt.​

​

4. Open the device's list that you want to change. (See screenshot below)​

EX: Network Devices​

​

5. Right click on the device name and click on Properties.​

EX: Network Devices​

​

​

6. Click on the Power Management tab. (See screenshot below)​

​

​

7. Uncheck Allow this device to wake the computer. (See screenshot above)​

NOTE: To Enable it again, just check this instead. If you need to disable the wireless mouse and keyboard, then you can wake the computer by pressing the power button on the case.​

​

8. If listed, check Allow the computer to turn off this device to save power. (See screenshot below step 6)​

NOTE: This will turn the device off when the computer goes into sleep mode.​

​

9. Click on the Advanced tab. (See screenshot below)​

NOTE: This is only for the Network device.​

​

​

10. Check the boxed in red Property: items below to see if they are set to Disabled in the Value: area. (See screenshot above)​

NOTE: This area may be different for your particular network device since it is based on the driver, but it should be similar. You will be looking for any Wake on type property options listed.​

​

11. Click on OK to apply and close properties window. (See screenshot below step 6 or 9)​

​

STEP 7

Check the Screen Saver

NOTE: Some screen savers can interfere with the computer’s ability to go into and come out of sleep/standby mode. Disabling or changing the screen saver may resolve the problem.

1. In the Screen saver settings, select an alternate screen saver, or set it to None, then click on OK.​

​

2. Test sleep mode.​

​

STEP 8

Check Startup Programs

   Note

• Many software components start up automatically with Vista and run in the background. Some of these programs may not be necessary, and can interfere with the sleep/standby mode. For troubleshooting purposes, use the following steps to prevent programs from starting up with Vista to see if this is the issue.
• If you are having these problems, you can avoid from having to do this completely if you logoff and put the computer to sleep from within the logon screen.

1. Open the Start Menu.​

A) In the white line (Start Search) area, type msconfig and press Enter.​

​

B) Go to step 3.​

​

OR​

​

2. Click on All Programs, Administrative Tools, and System Configuration.​

​

3. Click on Continue in the UAC prompt.​

​

4. Under the General tab, dot Selective startup. (See screenshot below)​

NOTE: When done with the test, dot Normal startup, to return to the default settings before the test, and click on OK.​

​

5. Uncheck Load startup items and click on OK and restart the computer.​

NOTE: You will get a notification that you made changes to the Startup programs in the bottom right Notification area. Just ignore it for now. It will go away when you put it back to Normal startup after you finish.​

​

​

6. Test sleep mode.​

​

7. If unchecking (disabling) Load startup items fixed the sleep problem, then enable one startup item at a time and test to see if the problem occurs again. Continue enabling startup items, until you find the program that is causing the problem. Remove or update the problem program.​

NOTE: See Method One or Two here: How to Check and Change the Startup Programs in Vista​

A) When done, change the setting back to Normal startup (step 4).​

​

8. If unchecking (disabling) Load startup items did not resolve the sleep problem, then set it back to Normal startup (Step 4) and go to the next step below.​

​

STEP 9

Check Scheduled Tasks for Programs

NOTE: Sometimes a program will have something scheduled to run that will wake the computer up. Try turning them off temporarily to see if it resolves the problem.

1. Check in the suspected program settings to see if there is a feature that may wake the computer.​

NOTE: Sometimes it can be the Auto-Update feature in the program.​

​

2. Check Task Scheduler for items that are set to Wake-Up the computer to perform it's action.​

A) Expand out the list in the left pane and click on the suspect item's folder. Double click on the task in the middle pane.​

​

B) Click on the Conditions tab.​

​

C) Uncheck the Wake the computer to run this task box.​

​

3. Check Windows Automatic Updates settings.​

​

STEP 10

Check Windows Sidebar Gadgets

NOTE: Sometimes a Windows Sidebar Gadget may cause the computer to not sleep on it's own.

​

1. Turn off Windows Sidebar as a test to see if your computer will enter sleep on it's own now.​

NOTE: Sometimes, you may need to restart the computer afterwards as well.​

​

2. If it does, then turn Windows Sidebar back on and turn off each Gadget one by one. Test sleep again after each one until you find the one causing the problem.​

​

STEP 11

Check Motherboard Jumpers

NOTE: A few motherboards have been reported has having jumpers on the board for certain functions (ex: USB device wake-up) that may need to be enabled or disabled.

1. Pull out or download your motherboard manual, and check for any such jumpers.​

​

2. If you have one that is related (ex: USB device wake-up), then test sleep mode inbetween toggling the jumper on and off.​

​

STEP 12

Reset Print Spooler

NOTE: This may help if your computer will sleep fine manually, but will not sleep automatically or not go to sleep at all. Credit to Artxie for this.

1. Open Services, and temporaily Stop the Print Spooler service.​

​

2. Open the Start Menu and type %WINDIR%\system32\spool\printers in the search line and press enter, then delete all files in this folder.​

​

3. In Services, Start the Print Spooler service. Close Services window.​

​

   Note

If the print spooler issue persists, the installed printer driver may not be compatible or corrupted. Check the printer manufacturer's website to download and install the latest Windows compatible driver for it.

STEP 13

Enable or Disable Windows Media Center Updates to Wake Up the Computer

NOTE: This will show you how to enable or disable the Windows Media Center (mcupdate) task from waking up the computer from sleep when it checks for Media Center updates in Windows 7 and Vista.

​

1. For how, see: Windows Media Center Updates - Enable or Disable Waking Computer - Windows 7 Forums​

​

STEP 14

View and Override Power Availability Requests

By using power availability requests, applications, services, and drivers can temporarily disable power management features to accomplish user scenarios. Availability requests can prevent the display from turning off after inactivity, and prevent the computer from automatically sleeping, enable Away Mode, and shutting down.

1. For how, see: How to View and Override Power Availability Requests in Windows​

​

​

​

​

​

STEP 15

Try System Restore

NOTE: If sleep/standby mode previously worked, attempt a system restore back to a time when it worked. If the problem has always existed, skip this step.

1. Save any open files and close all programs, then backup anything that you do not want to lose to be safe..​

​

2. See: How to Do a System Restore in Vista​

NOTE: If System Restore resolves the problem, the problem is probably caused by software that was installed after the restore point date.​

Ok thank you brink

You're welcome Jon.

Hi everyone, Firstly thank you for the great tutorial! i have spent two weeks working on this issue and have finally resolved it. between this thread and some other sites i noticed a couple of people in this thread with the same problem behavior as me and dozens of them in Hewlett Packards forums. My problem was sleep mode would work fine once then the second time the monitor would shut down but the hard drive remained active and nothing would wake it. so i would shut the power button down and restart it. as soon as i pressed the power button it would drop into a proper sleep state and then reboot (almost like initially it got stuck half way dropping into sleep) like i say after reboot sleep would work fine once but not a second except when running solely AC power or solely DC power sleep malfunctioned straight away. anyway i tried everthing including formatting and reinstalling windows, updating bios and drivers, different power modes, setting bios back to default then today i opened the case dropped out the cmos for 10 mints problem still there so i removed the memory sticks put only one back PROBLEM SOLVED! put the second stick back in problem back again so all along the problem was one of my memory cards even though no memory problems were displayed in sys. info or with windows memory diagnostic tool. well i hope my experience can help someone else who has not yet resolved thier sleep problems (or mabee check the easy things before reinstalling windows like i should have)

My system goes into Sleep Mode only for a moment then starts again. I ran the recommended test to see what woke it up and it said the wireless keyboard/mouse. I have a MS laser wireless 7000 set that uses a USB. I would think that since everything is MS that there wouldn't be any conflicts. I didn't change the bios settings because I don't know how and I'll bet the result would be the same as the previous poster.

So does this mean that if I want to use Sleep or Hibernation mode that I have to scrap my new desktop set and buy a wired one? So is this a MOBO or Vista issue?

 

[Brink]

Hello Saidas,

Did Step Four report this as the device?

As a test unplug your mouse to see if the computer still wakes up afterwards.

 

[Saidas]

It was step 4. There was also something about a Hi Def Audio device but I have no idea what that is.

 

[Brink]

That would be your sound card or integrated sound chip. As a test, you can disable the sound device in STEP FIVE to see if that helps. Be sure to write down the exact name listed for the device so that you can enable it again later if needed.

Have you already checked in STEP SIX to see if your network adapter as it's Power Management settings set to "Allow to wake computer..."? Also check in STEP TWO to make sure the When sharing media is set to Allow the computer to sleep.

Hope this helps.

 

[Saidas]

Before when I turned off the audio device I lost all audio on my pc so I turned it back on and haven't done anything else since then. How can I turn off the audio device and not lose the sound and how would I disable the wireless keyboard & mouse and still be able to use them?

I'd still like to know if this is a MOBO or Vista issue.

 

[Brink]

Well, about the only way to tell for sure is to remove your current keyboard and mouse to see if they are indeed waking up the computer.

You might also see if the latest 7.0 drivers from Microsoft may help.

 

[Saidas]

Thanks, but you address the HD Audio Device issue and if this is a MOBO or Vista problem. For the HDAV, it shows that it too is waking the system up but if I disable it then I get no sound.

 

[Brink]

You might see if there is a new audio driver version that you can install that may fix this issue.

 

[calabrache]

Hello, I'm using a Lenovo T61p 6460-6xg running Vista U, Sp2. The powercfg -a shows S3 ay hybernation mode only available, which is unfortunate becase as you explained, S3 runs on battery although reduced (10% of the battery per 24hrs). Is there a way I can make it run in S4 mode or is that only set by the firmware ? Regards

 

[Brink]

Hello calabrache,

You may still be able to enable hibernation and use it if that is what you are wanting to do though.

Hope this helps,
Shawn

 

[calabrache]

THanks for the quick reply. The hybernation is on - as per your tutorial (i actually found it and applied before asking you this question). I can see the hybernate file the the explorer (a 3gb file, like the available RAM), as well as in the disk cleaner. But what I notice is that the computer does still use a bit of battery while on hybernation - where I hoped it would be possible to make it hybernate in the S4 mode when it would not use battery. Would you have any advise. Thanks Brink, regards

 

[Brink]

Did you have hybrid mode enabled where your computer will go to sleep first for a bit, then later go to hibernation?

 

[calabrache]

I'm not quite sure to undestand the question : here is some aspects that might help -powercfg -a states that s3 is available on the system, while s1 & s2 are not supported by the firmware. No word on S4 - the start buton does show hybernate a option - i can notice a file stored at the root called hyberfil.sys of 3gb - the disk cleaner show the option to clear the file (as indicated in your tutorial) - in the power plan the hybernate is set after 20min, and the hybrid is to Yes Does that helps ? Regards

 

[Brink]

Yep, that helps. Set Hybrid to "Never" in step 8 of the STEP TWO section for the recommended settings for hibernation. That should allow you computer to save to the hiberfil.sys file and then go into hibernation without using any of the battery.

 

[kaworito]

I'm having the same problem as many people here but I still haven't been able to solve it. I was using Hibernation on my laptop ALL the time, so it was working perfectly before... it's just after I installed Adobe Dreamweaver that I stopped being able to put my computer into hibernation mode.
Everytime I try to hibernate, the screens turns off for a few seconds and after that it just takes me back to the login screen.

I have followed all the steps in the tutorial (except the restoring one because it seems I lost all my restoring points), and I still can't seem to find the solution. I have disabled all the devices that were able to wake my pc up, changed the energy management options, everything.

I also uninstalled Dreamweaver and the problem is still there.

Any suggestions?

 

[Brink]

What does it show you in STEP FOUR as to what last woke up your system?

 

[calabrache]

Hello again, i've attached two screen shots.
powercfg -lastwake and the way it is set up

The computer goes into hybernation but it is still S3 type of hybernation and takes about 10% of the battery per 24hrs

Your help is much appreciated, best regards
