To shut down or to sleep, what`s better?
what`s better to put it to sleep or shut it down?
Sleeping
Many computer users almost NEVER shut down their computers. There are many positive benefits to this (especially if you're a Mac user). When a Mac goes to sleep, almost every component inside the computer is turned off; what is not turned off is set in a 'low-power mode'. The contents of the RAM and Video RAM are saved, the network ports might still get a little power, and a few other subsystems stay on, but pretty much everything else is off.
On a laptop, this mode uses VERY little battery power - if you're going to use your laptop again within a day or so without the power adaptor plugged in, this could actually save battery power, as shutting down/starting up uses a lot more energy (much more disk access, processor power, etc.). On a desktop, this could save a little energy (thus a few $$$), especially if you put it to sleep a few times a day when you know you won't be using it.
The best advantage to sleeping is that the computer (a) goes to sleep almost immediately, allowing quick transport of a laptop, and no vigilance after clicking 'Shut Down...' on a desktop, and (b) wakes up almost immediately, allowing you to get to work right away.
Shutting Down
Shutting down a computer has a few benefits as well. One is that NO power is being used at all - for laptops, it's best to shut it down if you're not going to use it for a day or two, as it will save a little bit of energy and heat from being wasted in your laptop. On a desktop, you might wish to shut down so that you can transport it, or if you won't use it for a long while.
Also, shutting down completely wipes away the computer's RAM (random access memory), which might have some corrupt/junk data left in it from various things the computer does. It also lets the computer's components cool down. I definitely recommend shutting down at least once a month or so.
However, when you shut down and start up your computer, the hard drive and other components get more wear and tear, and use more energy.
The Verdict
I recommend all Mac users to sleep their computers unless they won't be used for more than a day or two, and all Mac users should shut down their computers at least once a month to clean out all the gibbledygook that collects inside the components.

Why is my computer shutting down instead of sleeping?
My comptuer is shutting down instead of sleeping. I have looked at my preferences a million times and nothing has changed regarding my sleep time or any other options.
I looked at another forum answer and tried resetting the SMU by unplugging the cord and holding the power button. That did not solve my problem. What should my next steps be? Should I reset PRAM? Should I suck it up and deal and bring it into a store? I am covered until October.
Please help. Thanks!Check System Preferences > Energy Saver > Schedule

I have tried everything! I have even restored to factory settings and the problem still exists. Instead of going to sleep my computer shuts down. I have checked power options and they look fine however when I change anything in the options it still shuts down instead of sleeps. I am thinking this must be a windows update issue but don't know which one. I have tried everything on every forum I found but no luck. Please help!
TIANot sure what to look for with USB software, I haven't really installed
anything that I know of is there a list of this USB online somewhere? The
laptop was new in August 2014, I got the Windows 8.1 update like the other
person did and it took forever. I think he counted 120 software updates. I
did not count them but it sure took a long time. That was about 3 months
later in November. Ever since then I've had the same problem and have tried
different things to circumvent it. It certainly appears to me that the
Lenovo has a severe bug in wakening from hibernate in 8.1 that was not
there in 8.0. And they should fix it. I'm about ready to throw the darn
thing out. Most of the time it doesn't come back from hibernate, you can
hear the fan run when you open the lid but it does not come up. other times
it does nothing until you press and hold down power. I thought HP was bad.

Shutting down instead of sleeping..
For some reason, my Mac keeps shutting down instead of going to sleep. I've checked all the settings and nothing I can find is set to shut down. Any idea what is going on? Possibly related... my Dashboard stuff keeps disappearing (see post in Finder,Dock discussions) Hope someone can help!
Any time you have problems with power management or sleep/wake or shutdown/boot there are a few basic steps to try. These apply both to Tiger (10.4.x) and Leopard (10.5.x) versions of the Mac OS.
First, reset the low level controller in your computer that handles power management and sleep/wake functions (including scheduled events). In an intel-based Mac that is the SMC. In a powePC-based Mac that is the PMU. To do this, go to the main Support page here and search for "reset SMC" or "reset PMU" as is appropriate in the search field at the top LEFT of that page. In the list of Knowledge Base articles returned, find the instructions specific to your model of Mac. It is not tough to do, but you do have to find the instructions for your specific Mac. Note that resetting a PMU may require you to manually adjust the date and time (System Preferences / Date & Time) the next time you log in.
Next, reset the Parameter memory (PRAM). PRAM holds copies of various system settings for rapid access and if it gets out of whack all sorts of odd things can happen. The instructions for resetting PRAM are the same for all Macs. Shut Down the computer. Locate the 4 keys Apple-Option-P-R. Press and hold those 4 keys, and while doing so, press and release the power button. Keep those 4 keys held down until you hear the SECOND startup chime, then release them. Your computer will continue to boot up normally.
Finally, perform a Safe Mode boot. A Safe Mode boot does some maintenance tasks in the background such as repairing critical system file permissions and deleting some cache files, etc. To do a Safe Mode boot, hold the "shift" key while booting until you see the spinning gear on the gray Apple screen. Be patient, this will take a while. Eventually you will get to a log in window that includes a notation that you are booted in Safe Mode. No need to log in as the maintenance stuff has already happened. So just Shut Down from there and reboot normally.
If your Sleep problem persists after these three steps, take a look in the Console to see if any helpful error messages are being thrown (Applications / Utilities / Console -- select "All Messages" in the column on the left). Now even during a NORMAL boot and log in, there are a lot of Console messages generated, some of which can look pretty scary if you are not used to them. But a normal Sleep or Shut Down should generate very few messages, so scroll back in the list to the time where you tried to put the computer to Sleep and see what you find.

Mac wont shut down, restart or sleep - corrupted software update?
My Mac Pro (2007 - OSX 10.6.7) will no longer shut down, restart or sleep. When I try to shut down, it logs me out of my user account, shows the light blue screen, momentarily shows the Leopard space background screen, before showing the blue screen again, and finally returning to the login screen prompting for my user/password.
The only way to poweroff from this point is to hold down the power switch until it forces a power down. This issue has been present for the last two weeks or so ever since I did a Software Update containing a security update. Initially it just failed to perform that update, although after a few days it did do the update, seemingly by fluke. After that, the problem persisted and now there is a new update (Fonts) which again fails to update.
I have tried all of the following:
Power off Mac, unplug power and leave for a few seconds
Power on Mac holding down Ctr + Opt + R + P (resetting PRAM etc)
Boot up from install CD and perform Disk repair (it did find problems with the disk and repaired them)
Check and repair permissions
Delete Software Update related plists & caches from ~/Library and /Library
Still the problem persists. Examining the logs shows me this:

I can paste the crash report referred to in the logs if that would be helpful but for now will leave it out as it's huge and largely full of gobledygook.
I'm at my wits end now. I've always been very proud that in ~4 years of Mac ownership I've never had to reinstall OSX - something I used to do on an anual basis with Windows. My next step probably is a full reinstall, but I really do consider it a drastic step and a last resort.
Here's hoping that the Mac Support Community can help me out
Thanks in advance.As a followup, upon the advice from someone else I created another user account (non admin) and logged in as that user. From that account I could successfully power down.
I'm still convinced the issue is related to Software Update as examining the logs showed none of the Software Update related entries as above:

When I click on my mail icon nothing happens...it won't open or quit (so I can't shut down my computer). What's going on?
Which Mail icon? That in the Applications folder, that in the Dock, or some other? You do not have to quit your applications in order to shut down your computer (heck, you hardly ever need to shut down your computer).

I have insurance through apple for my iPhone 4. Last night my phone was stolen. Am I covered under insurance to get a new phone? And how much will it cost? Second- what should I do about it? I don't know if I should shut down the phone or what in case my iPhone is able to be located or what not?

No, you simply do not. Apple does not sell insurance.
Apple offers an Extended Warranty called AppleCare.
Warranties doe not cover lost or stolen devices. Buy a new one. -
After installing Mac OS 10.5.8 my 2005 iMac G5 shuts down instead of sleeping
After install of OS 10.5.8 my iMac G5 - 2005 model, no Intel processor - whenever I choose sleep from the Apple menu or the time-out goes to sleep mode the computer shuts down instead of sleeping. Any insight would be appreciated.
Thanks.Try using Disk Utility t repair your disk
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Then reboot and repair permissions from your internal drive.

The startup disk may need repairing...
Startup your Mac while holding down the Command + R keys.
From there you should be able to access the built in utilities in OS X Recovery -
MacBook pro shuts down instead of sleeping while connected to power adapter
Hi there,
I am currently facing a rather strange issue. My old MacBook pro (about 2 years old) shuts down instead of sleeping but only when it is connected to the power adapter. I mean it goes to sleep mode perfectly well when it works only with the battery. Is it a know issue ? I'm running 10.5.6 and this problem is quite new to me (happened the first time some weeks ago).
Thank you in advance for your answer.You might try resetting the SMC and see if this helps:

How do you prevent the computer from shutting down when in sleep mode?
How do you prevent the computer from shutting down when in sleep mode and plugged in?
Thanks tjk.
Those are great suggestions and got me looking in places I had not considered before. Unfortunately, the problem remains. The System Preferences did not have the shut down option activated and there are no parental controls active on the computer.
Any other suggestions are welcome.

IdeaPad U400 shuts down when in sleep mode
My IdeaPad U400 shuts down when sleeping. All programs terminate.
I reviewed another poster's complaint about a similar problem several months. The response instructed the user to update the computer's drivers.
I have updated my drivers. My computer still shuts down regularly while sleeping. Please help!Hi RuthAnne,
Welcome to Lenovo Community Forums!
I’m sorry to hear that the issue still persists even after re-installing the drivers as suggested in the previous posts, I also assume that you have updated the Video Driver(Win 7 or Win 8) & Chipset Driver (Win 7 or Win 8)specifically and checked if this resolves the issue.
If the issue is same even after installing the above mentioned drivers, please backup the Data in the computer to any external hard drive and perform OSRI (Operating System Re-Install) to check and confirm the issue is with the
OS (Operating System).
NOTE: If the computer is shipped with pre-installed operating System OSRI can be performed using the instructions in U400 User Guide click here, check the steps to perform OKR(One Key Recovery) on page 23.
Hope this helps!!!
Best Regards
Shiva Kumar

Macbook shuts down instead of sleeps
I have a 2ghz core duo macbook (modle No. A1181 (EMC 2092)) that I recently restored from a time machine backup. It was at 10.5.5 and now its at 10.6.8. So, right now I close the lid of the macbook and immediatly shuts down instead of sleeping. The previous macbook (the one I made the back up from) didn't have this problem and nor did this one before the upgrade. I have already tried resetting the smc and the pram. Anyone have any ideas?
Having never shutdown my laptop, I was guessing on its reaction to closing the lid. So, I shutdown my MBP and closed the lid. It did continue the shutdown, so there seems to be a problem with yours.
Sometimes, sleep and shutdown issues can be solved by resetting the SMC -
Since I installed Mountain Lion, my iMac has shut down after 15-20 minutes. I have adjusted screen saver, shut down time, and sleep after. Nothing seems to help, any ideas?
As old as your iMac is, have you cleaned out the dust? Dust buildup can lead to over heating issues. Remove any and all things plugged into it including the power cord, Remove the RAM access grille. Vacuum all openings starting with the RAM access area (air intake). Vacuum all ports and plugs, DVD slot and the opening across the top of the rear of the body. Blow compressed air through all your openings and vacuum again to remove any dust you loosend. Reinstall the RAM grille. Plug in the keyboard and mouse if not blue tooth. Insert power cord...
You are now in a perfect position to do a
SMC RESET
http://support.apple.com/kb/HT3964
Shut down the computer.
Unplug the computer's power cord and ALL peripherals.
Wait 15 seconds.
Attach the computers power cable.
Wait another 5 seconds and press the power button to turn on the computer.
It is the 5 second timing that initiates the reset.
