If I am stepping away from my laptop for about 10-15 minutes or so, what is better to do - leaving it there and waiting for the screensaver (or just activating it) or instantly putting it to sleep? Is it okay to put it to sleep for 30-45 minutes? What about an hour+? I currently have a Screensaver set to 3 minutes after inactivity, and sleep mode for 5 minutes. Should I leave my screensaver on 3 minutes (lowest setting) and put sleep on "never," or put it to sleep manually when I know I am going to be away for it for over 15 minutes or so? What is best for my computer's health, if either at all? Thank you to anyone that gives a response.
