I am confused about when to Shut down my iMac rather than put it in Sleep mode. I've heard suggestions ranging from shutting it down once a day to once a week to once a month. What is the right interval, and/or what are the factors that would determine which mode to use? Many thanks P.S. My computer is actually the 20" but I don't suppose that matters
Well, to give you a tip:
shutting down your imac (well, same with other types of pc) saves you electricity, and refreshes your pc as well. but there are times that you need to put it in sleep mode because you use it frequently. So it's up to you to decide since once you need it right away and you shut it down might take time for you.
It depends on how long computer is being used in a day.
for general use
you can shutdown your computer once in 2 days but i highly recommend not to put in sleep mode and betting putting in hibernate mode instead of sleep mode.
note: most of simple issues are resolved by restarting PC so you can guess now how important is to shut down computer.
Good luck,
Sleep mode on a Windows 7 PC saves power without you having to turn your computer off and without losing any work.
This option cuts the power to your monitor, powers down the hard drive and pauses all functions until you awaken the computer from hibernation.
Whether you have a laptop, desktop or workstation, putting your computer into sleep mode will lower your electric bill and save money!
Click the "Start" button in the lower left corner of your desktop. In the lower right corner of the Start menu, next to the "Shut Down" button, is a button labeled with a small, right-pointing arrow. Mouse over the arrow.
The Shut Down menu appears.
Point at "Sleep" and click on this option.
Your Windows 7 computer goes into sleep mode.
Wake your computer from sleep mode by jiggling the mouse.
There may be a delay of a few seconds before your hardware powers on.
All of your open programs are still open and your work is intact, just as you left it before the computer entered sleep mode.
Configure your Windows 7 PC to go into sleep mode automatically when it is not used for a certain amount of time.
Click "Start" and select "Control Panel." Click "System and Security."
Click "Power Options."
A menu opens.
Click on "Choose when the computer sleeps" and select the number of minutes of inactivity. You can also set a separate time interval to put your monitor into sleep mode.
If you set both to 10 minutes, then your PC and monitor will automatically go into sleep mode after 10 minutes of inactivity
