Sleepless in Seattle
Having problems with your sleep? Well, I can’t help you with that. Try reading an RFC or something.
However, if it’s your computer that will not go to sleep, I have a suggestion. In the network adapter’s properties is a Power Management tab. There are three checkboxes that control Wake-On-LAN.
Make sure the last (indented) checkbox is checked. Otherwise your computer will wake up when anything on the network tries to communicate with it.
If you don’t have a managed network and you never need your computer to wake up, then you can clear the bottom two checkboxes completely.
If, when you put your computer to sleep, it immediately wakes up again, this could be one possible reason for that.
