Computer Wont Go Into Sleep Mode - Windows Fix

Sometimes, for whatever reasons, a computer or laptop will not go to sleep when you try to enter sleep mode. This personally happened to me with a Gateway Laptop that had Windows Vista on it. I had owned the computer for only about a year before this problem started occuring and I knew that any computer shouldn't be having problems this early in it's lifespan, especially since I had always taken care of it and watched what I downloaded or installed on it.

I became so frustrated because whenever I tried to put it into sleep mode it just would not go into it and I was worried my laptop was going to burn up or malfunction as a result. So I tried a few things out, researched for days on end, and finally found multiple ways to put it into sleep mode.

So if you're experiencing anything like the frustrating situation I found myself in with my laptop, here's a few tricks and steps that will most likely work for your predicament as well.

Change the Power Options
The first step we will try is to change your power options, since this has worked for some people. To do this, go to Start Menu>Control Panel>Power Options (In Windows 7 and some other versions of Windows this would be Start Menu>Control Panel>Hardware and Sound>Power Options). Now you will see a menu that allows you to change your Power Plan. Choose any plan and under it, click on "Change plan settings".

On the next menu, choose "Change advanced power settings".

Once you do that, a pop-up menu will appear. From that menu, click on "Multimedia settings" and then click on "When sharing media".

Now you will see two options "On battery:" and "Plugged in:". Click on the bar next to both of these settings and choose "Allow the computer to sleep" for both of them, if the bar doesn't already say that. Click "Apply" to save the settings and choose "Ok". Now try to put your computer to sleep and see if that did the trick.

Remove Privileges
If that option didn't work, the next step is to take privileges away from some of the devices on your computer that allow them to wake it up. So first we'll start with the mouse and other mouse-like devices.

So from the Windows start menu, choose Start Menu>Control Panel>Device Manager>Mice and other pointing devices (If you can't find Device Manager, then choose "classic view" from the menu on the left in Control Panel and then it should show up amongst the options to the right).

Choose your mouse or touchpad with right-click.

Click on Properties from the pop-up menu, then click on the "Power Management" tab at the top for each mouse or device you choose. If there is no Power Management tab, ignore it and move on to the next device.

Where there is a Power Management tab, click on it and uncheck the box next to "Allow this device to wake the computer". (If you can't find Device Manager, then choose "classic view" from the menu on the left in Control Panel and then it should show up amongst the options to the right).

Try to Put Computer to Sleep Now
If that didn't work, return to Control Panel, and undo the changes you made with the Mice and other pointing devices menu. In other words, make sure the boxes are checked again instead of unchecked.

The reason we are doing this is because we're now going to do it with your keyboard instead of your mouse devices, and if we leave both the keyboard and the mouse unchecked, you may have problems waking your computer up from it's sleep if none of your devices are allowed to wake it up.

So we leave one device, either the keyboard or the mouse, with the power to wake it up. Now follow those same steps you followed earlier, but this time you're going to do it for "Keyboards". Instead of choosing "Mice and other pointing devices" from the menu, click on Keyboards, then right-click on each Keyboard device, choose properties, then click on the Power Management tab again (on the keyboards where it's visible) and uncheck the box for 'Allow this device to wake the computer".

Do this for each keyboard device on the list. After that, choose "Start>Sleep" again to see if the computer will stay asleep this time.

Check USB Devices
If none of these options worked for you, make sure you have no other devices plugged in to your computer. Unplug any usb devices you plugged in to your usb ports, or any other devices plugged in to your computer that may be causing the problem.

Don't just turn them off, but actually make sure they are completely unplugged, because the plugs themselves may be the cause of your problems. In my case, it was the keyboard that did the trick.

My keyboard must have had a button malfunctioing so when I put my laptop to sleep, it thought I was pressing one of the buttons and woke the computer up again. This could be because either the keyboard itself is broken, or more likely, because I have an internal problem with the motherboard or RAM. My laptop had been acting up before all this with other problems, so that might explain it.
