Shut down or put to sleep?

I am in and out of my iMac numerous times a day and been wondering to shut it down or just put it to sleep?The obvious answer would be to put it to sleep but what I like to know if in sleep mode the hard drive is still spinning? which is more harmful to the hard drive spin all the time or the frequent shutting off and on?

Put it to sleep. In System Preferences/Energy Saver is a setting for putting the hard drive to sleep whenever possible. It should be going to sleep with the computer.

MacBook Pro shuts down when put into sleep mode

Every time I put my Mac into sleep mode (plugged in or not, charged or not), it shuts itself down, and I have to restart it. I just got it (brand new) in August, so I know the battery shouldn't be bad.
It's been doing this for about a week... I just changed to Snow Leopard yesterday, and downloaded the software updates and everything, but it still shuts down.
Anyone know what I can do (short of sending it to Apple) to fix this?

Okay, well I already used smartsleep.
It fixed the problem I was having, but now my macbook started having the same issues again this weekend. It's happened twice tonight in the span of 3 hours.
Do I need to uninstall SmartSleep then?
And here is the report I get when the macbook reboots:

Shuts down when put into sleep mode

Any idea why this is happening?
When my ipod touch locks itself or if I put it into sleep mode, it will not wake itself up with the press of a button - instead, it restarts (black screen with apple logo in centre).
It is only 12 hours old and was perfectly fine when running on the factory 1.xx software, it has only started happening since the 2.1 software was installed.
Since, I have Restored it through iTunes which performs another clean install of 2.1 and it is the same still
Weirdly, while it is connected to my PC through the USB cable, it behaves perfectly (waking up from sleep instantly with the press of the home button), but as soon as I disconnect it from the PC, it starts playing up again.
If I set the settings to never lock, it performs brilliantly which is annoying as I now have a taste of what this device can do, but I just cant put it into sleep mode.
Any ideas on what I need to do? Or is it a case of returning it to Apple?
Thanks for any response

Is the battery FULLY charged? If not, charge it and then see how it reacts...make sure Wi-Fi is off while you do this--I've noticed weird things when it's docked and plugged into my TV (with the new dock) and wi-fi is on--I get battery messages randomly and it eventually shuts down (even though it's plugged into a dock with power, that came from Apple and is the "latest and greatest"...)

Dual boot computer restarts by itself shortly after it has been shut down or put into sleep mode

Hello,
I have Toshiba Equium L40-14I (old) and dual boot Vista and Linux.
A few days ago I noticed that while in a Linux operating system and when I put it to sleep (suspend) it would do so, but then immediately come alive again. The same thing happens with the shut down option. In Windows Vista it is the same. It does shut down, but in a few seconds restarts again and shows the normal options of choosing which operating system I want to boot. The computer only stays shut if I pull the power cord (it has no functioning battery) or it I forcefully shut it by pressing the power button for a few seconds.
So far I tried this:
- BIOS: 1. Changed to default factory settings. 2. Disabled wake-up on LAN and disabled wake up on keyboard.
- Device Manager, Network adapters, NIC, Properties, Power management: unticked the option that allows the adapter to wake the computer
- Device Manager: all drivers seem to be ok
- Virus scan: although this is probably not the issue as it happens independently of which operating system I am using. I have not installed any strange programs.
- I started from the Safe mode and then shut down. Same thing happened: it restarted automatically after a few seconds.
- Disabled automatic restart on system failure. It didn't help.
English is not my first language, sorry for the perhaps unclear way of describing this issue. I would appreciate any help. Thank you.

You have done just about everything I can think of. You didn't mention doing a System Restore. If you haven't done one or even if you have, do a System Restore back to at least sometime before this started happening. If the first one doesn't work, try a different restore point and do it again. If that doesn't work, you need to consider a full HDD recovery to out-of-box condition which procedure is fully covered in your User's Guide. I'm sorry I don't have a link for it but yours is not a U.S. machine and this site is for U.S. machines. It appears to be a U.K. model with support covered by THIS site.
BTW, I wish the native Americans who post on here did as well as you have so you have to make no excuses for your English.

IMac shuts down when put in Sleep mode

Computer works fine but when I put it in "sleep" mode in shuts down and cannot be restarted without unplugging and starting over. Once started it works fine again until the next "sleep".
Anything I can try before backing everything up and heading for the Apple store ?

Disconnect all devices except for the keyboard & mouse if you have not done so.
Try this:
Change the energy saving options, to put the display to sleep and the computer to sleep at the same time.
Enable (check mark) put the hard disk to sleep when possible.
Lock the padlock.
Optional: Repair permissions &/or restart.
==============
Check your Energy Saver settings to make sure they are correct.
If your computer came w/a remote, test the remote sleep option to determine if your issue is repeated.

10.5.7 Shut down when put to sleep

I updated my macbook pro sr to 10.5.7 today and noticed that when i close the lid, it shuts down after about 5 minutes. My battery is about brand new with under 60 cycles on it. I am wondering if anyone else can verify if this problem is only mine or something others are dealing with. I am sure that this started today after the update, as I had the computer asleep all day yesterday while at school. BTW, the mac is unplugged when it shuts downs. Thanks for any feedback.

Here is a log of what happened last night. It shut down randomly today also but there was no error report that I could find. I deleted the plist file as suggested but have not yet restarted the system. I am trying it now. Hopefully you have some ideas from the log. If you need more info out of it, let me know. What I have gathered is firefox is what is crashing. Just updated that same day as 10.5.7 I believe. Will see if it still shuts down with firefox off. Thanks for your help again Yang.

Macbook pro shuts down when put on sleep (OS 10.8.6)

I have a Macbook pro (OS 10.8.6), when I put it to sleep by closing the lid or explicitly choosing sleep option,it goes to sleep, but when I open the lid, the machine shutsdown. I have to press the power button for around 30 seconds to start the machine. In the logs I could find--Shutdown due to error code --79 and sleep failure shutdown.

Maybe some things to try check/try

MacBook will not shut down or go to sleep

My MacBook is not shutting down or going to sleep.
When I try to shut down: The desktop disappears as normal but then the plain blue screens appears (with the little circle down the bottom which spins (not the beach ball)) and it just stays there forever. To shut down I need to hold the power button for 10 seconds.
When I try to put the MacBook to sleep by closing the lid: The light in the bottom right hand corner comes on but it does not "pulse" - suggesting it has not gone to sleep.
When I try to put the MacBook to sleep using the Apple (top left hand) menu: Nothing happens.
I am not 100% sure when this started happening, but I believe it either started happening after:
a) The firmware update which was supposed to fix the "mooing" problem"; or
b) One of the system software updates.
If you need my current system/firmware version, you will have to tell me how to do this because I don't know how to find these numbers.
This is really frustrating because I move my laptop around a lot so I would like to be able to use the shut down/sleep functions. Any help would be greatly appreciated.

First couple things to check is do you have any external drives plugged into the Macbook? My macbook would sleep because I had an external drive that prevented it from sleeping.
Also, check what's loading at Startup. There might be a program that's preventing this. Something that constantly needs internet access would cause this. Open up your System Preferences/Accounts/Login Items. See if something in there could be causing the problem.
Hope that helps a little.

Computer shuts down without going to sleep

hello,
i've had an increasingly swollen battery with a corresponding diminished life. to a point that it barely fit, lasted ten minutes on its own and when it became depleted, the macbook pro would just shut down without a warning.
so i bought a new one and although it lasted about 2h30 on its first cycle, when it displayed the low battery warning, the computer shut down without going to sleep...
tried resetting PRAM, and SMC to no avail.
i charged it back up a bit and it shut down again.
it's on its 3rd cycle and battery health already dropped from 100% to 94%.
anything i can do?
thanks...

Are you sure it is shutting down and not going to sleep "permanently"? I say this because I have (and others) a somewhat similar problem but it's not shutting down, it sleeps forever:
http://discussions.apple.com/thread.jspa?threadID=1400708
Also, I was going to suggest maybe your battery has died out, but you said it is plugged in, so probably not your battery as the problem.

MBP will not start up. was working fine and shut down and put to charge and now will not power back up. Screen will light up and then power shuts back down. Any thoughts?

IMac shuts down after putting it to sleep

Lately, my iMac G5 has been shutting down automatically after putting it to sleep. If I wake it up within a short period of time it is OK, but if I wait several minutes, it must be restarted.
Did I accidentily change a setting? Or is it a problem with the hardware?
Is there a setting I can check? I have tried to find one in Energy Saver and other places without success.
Thanks,
-tee

Welcome to Discussions - Please tell us which model G5 iMac you have (iMac release dates).I don't think you changed anything, I would suggest that you reset the SMU and see if that helps.
Please post back,
Miriam

IMac won't shut down or go to sleep - keeps rebooting or turning display back on. Is there any way to fix this?

A friend's iMac (2010 - Snow Lepord - 27" display) won't allow them to shut it down or put it into sleep mode. The system continually reboots itself when using the Apple > "Shut Down..." command. Similarly, it continually turns the display back on when using the Apple > "Sleep" command (even when no additional movement or action has taken place).
The only way to turn this monster off is to press and hold the power button behind the screen (lower-left). Does anyone have any ideas as to why this might be happening and how to fix it?
Many thanks in advance!

Have you tried an SMC reset?

G4 shuts down when trying to sleep or restart

Hello,
I've looked around on the forums but can't find the same problem as mine. When I try putting my G4 to sleep, it powers off right away. Same thing when trying to restart, it just shuts down. If it hasn't been on too long, I can press the power button and it will start. If it has been on a while, I have to wait 15 minutes or so until the power button will work. I tried replacing the PRAM battery and resetting the PRAM.
I'm running 10.4.11. Gigabit ethernet G4 running a single Sonnet 1.8Ghz, with 1.5GB RAM. Boot ROM 4.2.8f1. I have two hard drives, one 120GB and one 160GB. Haven't changed any hardware recently.
Is my power supply going bad? I replaced it about 3 1/2 years ago.
Any ideas would be greatly appreciated.

What do I do if an iPod shuts down after going into sleep mode

My friends iPod keeps shutting down after it goes into sleep mode. I just fixed it up (restored it, had to dry it out after it fell into water) and now it does that. Everything else works fine but if I put it in sleep mode or put it into sleep mode it shuts down. How do I fix this because I've never seen this happen before.

Hey Tecmo_SB_Guy,
I would suggest you take a look at advanced power settings. It can seem like the notebook is turning off when it is actually just hibernating. You can set it to not hibernate.
1. Windows key + Q to open the Search Bar
2. Type "power"
3. Click Settings under the Search Bar
4. Select Power Options from the results on the left.
5. In Power Options, Click Change when the computer sleeps, on the left.
6. Set the Put the computer to sleep setting so that it fits your usage best.
7. Click Change advanced power settings, at the bottom.
8. Expand Sleep and expand Hibernate after. If you want you can change the hibernation setting to Never by typing "Never" into the minutes field. See attached picture. You can do this for battery and/or plugged in.
9. Click Apply to save changes.
If you don't already shut it down periodically, I would suggest shutting it down at least 2-3 times a week if you use it daily. Leaving the computer running continuously can shorten its lifespan. Hard drive failures and motherboard issues are seen much more often on machines that are left running constantly. Computers get bogged down and run slowly when the memory is full. Memory only clears out and resets itself when the computer is shut down. Here is a link explaining more about memory accumulation and hardware aging.
I hope these suggestions help! Please let me know if you have any questions
