I’m having trouble putting my computer to sleep.? Could there be some reason why it won’t go to sleep or immediately wakes up when I put it to sleep?? My computer is running Windows Vista but I’ve noticed that when I unplug the computer from the internet, it sleeps.? Why is it being so confusing.
Windows Vista has some unusual changes with devices and internet properties that usually lead to issues with putting a computer to sleep.? We’ll use the device manager to edit and modify the properties for select components on your machine that are causing your computer to “stay awake.”
In your specific case, you included a very important clue to make the diagnosis to your problem.? The little snippet of information about being disconnected from the network allowing your computer to sleep lets me know exactly what issue is causing your computer to stay awake.
Every computer usually is equip with a network card (which is where you hook in that blue cable to get on the internet).? On Windows Vista, sometimes the computer is set up to have a setting that will make the computer stay awake or be woken up whenever network activity is detected, which is pretty much on all the time.
Open the device manager, *Start >> Run >> “devmgmt.msc” without quotes >> Enter.
Look for the network adapters option and click on the plus sign to the left of it.? Right click the network adapter and open the properties.? In the power management tab, uncheck the option “Allow this device to wake the computer.”
Click OK and you should be good to go! Enjoy the sleep.
