My Windows 7 Professional machine goes into hibernation when I am away from the device for over 40 minutes. This interrupts batch programs that I run -- some of them requiring six hours.
Microsoft recommends as administrator giving the DOS command "powercfg.exe /hibernate off" in the root directory of the volume containing Windows. Very nice, but it doesn't work.
How can I get the machine to stay awake until it finishes intense batch jobs?
