I want to run a very very long term application on my eMac, i will be scanning a failed HD with DataRescue2. The last time i did it midway, took almost a month, 24/7 without interruption. My goal here is to consume as less electricity as possible. How can i do that on my eMac and still have the application to run in the background! Is there a way of turning of the monitor (only) in order to consume less electricity?
