Wireless LAN feature

Having your PC go into Sleep state when idle is a good way to conserve power. But what if you need to access your PC remotely? In Windows Vista, you can wake another PC in Sleep state only if it has a wired network connection. In Windows 7, you can use the Wake on Wireless LAN feature to wake the PC over a wireless network connection. Let’s say you’re using your laptop in the bedroom and want to see a photo on the PC in the kitchen. Because both are connected to your home network, it doesn’t matter if the
kitchen PC is in Sleep state, because you can use Wake on Wireless LAN and view the photo. Similarly, the IT administrator in your company can wake up wirelessly connected PCs to apply software updates or perform other maintenance—and save on power costs too.
