So playing around with Windows 7 has been fun, but there are a few quirks. For example, on one of my laptops, Windows 7 does not go to Sleep mode. It looks like it is about to go to sleep, but instead wakes up immediately.
Other times it sleeps, but wakes up randomly even though I didn’t open the computer. And sometimes, just to be difficult, it doesn’t go to sleep at all! If you are having sleep mode problems with Windows 7, you’re not alone.
There are a few ways you can try to solve this unable to sleep problem in Windows 7 problem. I’ll go through all the steps below.
Method 1 – Update Drivers
The very first thing you want to do if Windows 7 is not going to sleep is to update all the drivers, especially for your video card. You can either run Windows update or go to the website for your hardware manufacturer and download them there. I would recommend the latter.
Method 2 – Configure Power Option Settings
If that didn’t work for you, the next thing to do is to make sure your Power settings are configured properly.
First, click Start, then type power sleep in the search box and click on Change when the computer sleeps.
Now, change the value of Put the computer to sleep to something new like 15 minutes or 30 minutes, but do NOT set it to Never.
Next click on the Change advanced power settings link at the bottom. Go ahead and expand Sleep and then expand Allow wake timers. Make sure this is set to Disable.
Scroll more and expand Multimedia settings, then expand When sharing media, and select Allow the computer to sleep.
Method 3 – Disable wake up computer devices
If the first two methods didn’t work, your issue might be caused by devices that automatically wake up your computer. You can try disabling the devices that might be waking your computer.
Click on Start, type CMD and then right-click on CMD and choose Run as administrator.
Now type the following command which will list out all the devices that can wake up your Windows 7 computer. Normally, it should only be your mouse and keyboard listed.
Powercfg -devicequery wake_armed
Now you can disable a device by typing in the following command and replacing devicename with the name of the device listed previously:
Powercfg -devicedisablewake "devicename"

You can also prevent the devices from waking a Windows 7 computer using Device Manager. Go to the Control Panel, click on Hardware and Sound and then click on Device Manager.
Expand the device you want to disable, right-click on it and choose Properties.
Click on the Power Management tab and uncheck the Allow this device to wake the computer box.
Method 4 – Check Power Interruptions
You can also use another variant of the powercfg command to check whether there are any devices or processes that are interrupting the system and causing it not to sleep. You can do this by first opening an administrator command prompt again and typing the following command:
If there is anything that could be causing the system to not sleep, it should be listed here. Note that not all items listed here are necessarily preventing the system from sleeping. For example, I have a microphone attached to the computer, so there is a message about an audio stream that is currently in use. You can try disconnecting the device to see if it makes a difference or not.
Method 5 – Run the Power Troubleshooter
Windows has a built-in power troubleshooter that could help fix the issue for you. Just click on Start, type in troubleshoot and click on the first result. This will bring you to the troubleshoot dialog, which has a bunch of different troubleshooters for different problems.
In Windows 7, click on View All and then click on Power. Hopefully, if you’ve been having this problem in Windows 7, these solutions will fix it! If not, post a comment and I will try to help! Enjoy!
