My computer wakes from hibernation. I’m using windows 7 x64. My BIOS doesn’t support any configuration settings about wake, and the LAN device driver states that it doesn’t support wake on LAN. It’s a Dell Lattitude laptop, about 2 years old. No events are relevant. This started about 6 months ago when I went out and updated all my drivers, so some driver is apparently having fun. I had already run for long enough when it started that I didn’t want to roll back, although I have tried earlier versions of the LAN, WAN and WLAN drivers. None of them have an option for disabling wake on LAN that can be checked. Any suggestions on how to troubleshoot this problem? powercfg –lastwake gives the very helpful... C:\>powercfg -lastwake Wake History Count - 1 Wake History  Wake Source Count – 0 C:\>powercfg -devicequery wake_armed gives no output. Help!
