I own a Dell XPS 1645 notebook running windows 7 x64. I was trying to rebuild the file system of an external drive (which can take a considerable amount of time). After approximately 24 hours, my computer entered sleep mode, completely erasing all of my progress. All of my settings are set to never enter sleep mode and the computer was never disconnected from the power source. Is there any other system that would have caused my computer to go to sleep?
