Power Save Mode is a computer setting that reduces power consumption and conserves battery capacity by shutting down hardware devices that have been idle for quite some time. When it is enabled, your computer goes into hibernation or standby mode when not in use. Disabling the Power Saving options on your computer prevents your computer from going to sleep during time-consuming tasks, such as backing-up a hard drive or converting a large media file to a different format.
