Put on sleep or shut down?

Hello. I actually wonder what is best for my mac regarding putting it on sleep or not. Shall i just shat it down whenever i finished from it. or leave it on sleep mode?

I just let mine sleep - I only restart about once a week or so or when an update or installation requires a restart. Very seldom do I ever shut down completely.

G4 mirror/when put to sleep computer shuts down, power up problems

I'm having some strange problems here, and I've looked through the topics and I can't find one that exactly fits my issues.
Recently my mac shut off when I put it to sleep and It would not turn back on, also the button would not light up when pressed. I unplugged it, checked the power source and when I plugged it back in the button light would come on when immediately touched and then go out, again not starting(note: my external hard drive comes on and after a few seconds shuts off). After trying it several times I gave up. About 4 hours later I tried it again and it started.
This has happened every time I've either shut down or put it to sleep. I feel very uncomfortable leaving my computer on all the time.
I tried the PMU reset my mac immediately started up, I thought problem solved until I put it to sleep again. Shut down wouldn't start up.
Exchanged batteries with the exact same computer from work, did a PMU reset, the Mac started right up. Put it to sleep same deal.
I am buying a new battery today.
I find it strange that when the mac is immediately shut down either by me or when it goes to sleep, the button light won't come on unless I unplug it from the back and replug it in. Then the button light will come on but not necessarily start up. I sometimes have to wait hours or it will come back on immediately.
right now its a crap shoot.
please help if you can.

Yuk. I don't even like to discuss this, but depending on the service, the filter caps in the psu and many other places in the system wear out and start causing problems. I would start monitoring voltages coming from the psu to the mother board using a digital multimeter. You can probe the white connector from the psu to the mother board from the top of the connector using a paper clip or dental pick on the connector pins. I believe this diagram is applicable to most of the ppc Macs:

Also consider that your drive may be at fault here. My DA does not like to be put to sleep. It does strange things when put to sleep.

IBooks in classroom - put to sleep or shut down?

I am an educator using 800 iBooks with high school students. We have a mobile cart that charges the units when the students return them to the cart between classes. Which would be more beneficial...having the students just log off of them, close the lid and return them to the cart...or...have the students shut them down between classes? We want to extend the battery length as long as possible (due to expense) but we are not sure of which process would be better?

Hi, and welcome to Apple Discussions.
If all you're worried about is battery lifespan, you may want to take a look at what Apple has to say about that:
http://www.apple.com/batteries/notebooks.html
I don't think it will make a lot of difference, since they're headed back to the cart for charging. They may charge a trifle quicker if shut down, so that may be a consideration, although it would be a minimal difference, I would think.

Should I put it to SLEEP or SHUT DOWN?

Greeting everyone. I recently purchased my first Macbook, my first laptop ever. I've pretty much grown up using a desktop pc. I turn it on when I get home, put it on sleep mode when I leave it to watch tv or what not. If I'm done with it for the day, I turn it off.
Now before everone jumps on me for probably doing the wrong thing please note that I come from a "Turn it off when you're not using it kind of family". Can someone give me some pointers in using my new mac? For example, someone told me that I can actually leave my macbook in sleep mode the entire day even when traveling to and from school/work. Is this safe for my macbook? I apologize if this is such an elementary question.

I have found that my machines respond better when I just close the lid (sleep). It is important to understand that the laptop caches everything in memory to the hard drive before it goes to sleep, so you want to make sure you allow the extra time for that to happen (wait until the sleep light starts pulsating) before you move the laptop if you can. Otherwise you're moving the machine while the hard drive is still spinning. I know that the newer laptops typically have a Sudden Motion Sensor that will automatically park the heads under certain conditions, but why tempt fate? Depending on how many applications you have running, and how much RAM you have installed, going into sleep mode can take longer than you might expect. Whether you adapt a sleep or shut down operating preference (I prefer sleep- only shutting down every once in a while for OS installs, restarts due to problems, etc.), it is much more important to follow Apple's guidelines for calibrating the battery. Not only does following these instructions allow the computer to more accurately report the battery charge level, it also runs the lithium ion battery through a complete cycle - something that is needed every once in a while to keep it operating in tip-top shape. The instructions for the procedure are found here:

Sleep and Shut-down menu commands

Our 500 MHz Power PC G3, upgraded to system 10.4.6, is a great machine and a real work horse for us. However, it has been acting up lately. The apple symbol drop down menu command that puts the computer to sleep, restart, shut down etc. will not respond. The key board commands for sleep etc. also don't work. I tried the Disk Utilitly- First Aid, both Disk Repairs and Permissions. "No repairs were necessary" for both. I even reinstalled OS 10.4.6 which seems to have complicated the problem and ate a big chunk of our precious little harddrive memory. Now every time I start up I get the warning message, "Application Launch Failure" The applicaton "Transport Monitor' could not be launched
because of a shared library error:"8<Transport Monitor><Transport Monitor><HotSyncLib.PPC><"
Could this be the root of the drop-down menu problem?

As I said, a weak or dead PRAM battery can reportedly cause odd startup issues. If it has never been changed in six years, that's a really long-lasting battery, even if the iMac was kept on continuously.
They are pretty cheap from the right source, so you may want to try changing it.

When waking from sleep, it shuts down

I use the energy saver to put the computer to sleep when I'm not using it. When I hit a button to "wake" the computer, it starts to spin up but then shuts down.
I was told by Apple (when I still had my call-in protection plan) that this was because there was no room on my hard drive. This first happened when I had about 1 GB left (60GB drive). I have subsequently bought an external drive on to which I have moved my music files and now have 25+ GB, so that should no longer be an issue.
Any ideas?

USB scanners are generally a red flag for sleep-related isuues but usually in terms of failing to wake or failing to sleep, not shutting down instead of waking up. You can check if the peripheral hardware is involved by disconnecting all peripherals other than keyboard and mouse, Starting Up in Safe Mode (to disable any peripheral drivers), and seeing if you can then sleep and wake the Mac without the shutdown problem.
The system.log messages indicate you have the Mac set to use a Virtual Private Network (VPN); I'm not familar wnough with that to be sure if it affects the wake-from-sleep issue. You may want to post that snippet from the system.log along with a statement of the problem in the Using OS X 10.4 Tiger forum part of the Apple Discussions in order to reach a broader audience than in the eMac part of the Discussions.
The 'SystemUIServer not responding' message may be helped if you try this:
-- trash /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-- trash /Users/[username]/Library/Preferences/com.apple.systemuiserver.plist
-- reboot while resetting PRAM
To reset PRAM, restart, as soon as the screen goes dark, hold down command-option-p-r until you hear three sets of chimes, then release the keys and let the Mac finish starting up. You may need to re-do some System Preferences settings after resettings PRAM (see What's stored in PRAM?)
BTW, a viable workaround is to change the Energy Saver settings to slepp the display only after XX number of minutes, with put system to slepp set to Never and put hard drives to slepp when possible unchecked. That also ensures the Mac can perform the background maintenance tasks overnight. If you normally shut down an OS X Mac overnight or leave it in system sleep, the cron maintenance tasks cannot run in their nominal 3 am timeframe. (Display-only sleep allows the maintenance tasks to run). Tiger 10.4.2 and later will force the maintenance tasks to run after sufficient time has elapsed, but kust how long is long enough, and whether the timer is reset on shutdown, isn't entirely clear. You can leave the Mac in display-only sleep a weekend or two a month; you can manually Force Background Maintenance; or you can use a third-party utility such as OnyX to run the maintenance. Note that any system utility you use must be compatible with the OS version (e.g., use the Tiger version of OnyX with 10.4.x).

Sleep mode shut down

i recently upgraded to 10.4.9 and everytime i put computer to sleep it shut down after about 5 min. i checked all energy set pionts and they are default to never shut down. what could be problem?

Try these diagnostic procedures:
1) Try trashing these 3 .plist preferences and reboot. Reset your Energy Saver preferences.
HD > Library > Preferences > SystemConfiguration > com.apple.AutoWake.plist & com.apple.PowerManagement.plist
User > Library > Preferences > com.apple.systemuiserver.plist
2) Do an Open Firmware reset: Hold the CommandOption+OF keys during startup. At the '>' prompt type:
>reset-nvram
Return
>set-defaults
Return
>reset-all
Return
Reset PRAM:
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound (bong) for the second time.
6. Release the keys.
3) Reset your PMU.

Cannot sleep or shut down when connected to TV through DVI

I recently reinvigorated my 2003 Power Mac G5 (Power PC) with a clean install of OSX Leopard and connected it to my TV via a VGA cable and DVI adapter. I soon discovered the computer would not sleep or shut down with the TV connected:
- Selecting "sleep" from apple menu, OR
- Pressing sleep button on original ADC monitor (with both monitors connected,) OR
- Waiting for 15 minute automatic sleep mode:
computer sleeps (tower clicks off as normal) but immediately wakes again
- Selecting "shut down" from apple menu:
computer shuts down completely but immediately reboots
When the G5 runs on only the original monitor, sleep and shutdown commands work as expected.
Aside from unplugging the DVI adapter every time I want to sleep or shut down, is there a solution to this problem?

I've seen the TV problem before, not sure there is a cure, but perhaps one of these...

Sleep or Shut Down with Mac Pro RAID Card?

I'll be gone for a four-day weekend trip, which is longer than the 72 hours claimed for the Mac Pro RAID Card battery. If I shut down and come back four days later, the battery will presumably be discharged. What will happen when I restart?
Asked another way ... is 72 hours the maximum amount of time that the computer should be shut down or do I simply restart and wait for the battery to recharge and the write caches to be re-enabled?
The FAQ for the Mac Pro RAID Card http://support.apple.com/kb/HT1346 talks around this issue, but doesn't say whether it is a good or bad idea to allow the battery to discharge for "... any length of time." Please review the appended excerpt from the FAQ and advise on whether I should sleep or shut down.
Regards,
iPhoton
Question: Why does RAID Utility show a yellow light and report the status "Write cache disabled"?
Answer: The write cache is disabled automatically so data cannot be written to RAID volumes when the battery charge is not sufficient to back up cached data for 72 hours. This message is normally encountered when a RAID Card is used for the first time, when the battery enters a conditioning cycle once every three months, or when a computer with a RAID Card installed is shut down for any length of time.
If your RAID card's firmware is M-2.0.3.3 or later, or E-1.2.2.4 or later, you can use RAID Utility to force-enable the write cache while the battery conditions itself. Warning: If you enable the write caches before the battery is fully charged, you might lose some data if the power to your computer is interrupted.

Thanks to everyone who replied to my message. I did a proper backup and normal shut down on Wednesday night and restarted on Monday morning. That was over 100 hours later and certainly more than the battery is specified (72 hours).
When I restarted on Monday morning I noticed ... no change! The battery was fully charged according to the RAID Utility, I received no warning messages, there were no new events in the RAID Utility log ... it's as if the extended shutdown never occurred.
So, an extended shutdown appears not to be a problem and I won't worry about it again, not even on my next extended shutdown for three weeks at the end of the year.

Is it better to sleep or shut down at night?

Is it better to sleep or shut down when I'm through with my iPad for the night?

I have been letting mine sleep when not in use since buying it new almost a year and a half ago...has never caused any issues with it. Only time it has been shutdown is for aircraft take off and landing.

Sleep or shut down at night?

Hi, it just occurred to me that in summer with frequent lightning storms especially during the night, might it be a good idea to shut the computer down and disconnect the power adapter at night?
I tend to use the computer plugged in during the day, with short periods of battery use, and then at night I leave it plugged in and just close the lid. Even with old PC's I did this without a problem, but with my new MBP I don't want to take any chances!
Thanks,
Karen

Thanks.. re. shutting down at night, I thought there was an issue of wear and tear from starting up so often.. otherwise it would certainly be simpler to shut down and not worry about nighttime power surges.
I don't worry about wear and tear, because although technically it might be better to run your computer at full power 24/7 to avoid premature wear from thermal and power cycling, realistically nearly every Mac user either sleeps or shuts down their laptop at least once a day whether that's at night or merely to transport it (since it is a laptop after all) and therefore powering off is the norm, and it is not causing mass early laptop deaths.
We are also weighing leaving the computer plugged in versus the potential damage from a lightning strike, and we're saying the potential damage from sleeping or shutting down at night is assumed to be less severe than that of a direct lightning hit.
Re. sleeping the computer all night and draining the battery, I do that once a month to calibrate the battery, but isn't it recommended to not drain deeply too often?
You are right that is is recommended to not do deep discharges too often. But an overnight sleep does not drain the battery that far, maybe a few percent. What I didn't mention is that if your battery is new and fully charged, it will probably last around a week in sleep mode. One night off the charger isn't going to drain the battery unless, as I mentioned, it's an old battery with a fraction of its original capacity.

Sleep or shut down the laptop?

Is it better to sleep or shut down the laptop? I mean in general for the laptop, not necessarily to save battery or anything. Thank you!

No need to shut down unless perhaps the laptop is going to be in a travel bag for a while.
I just close the lid to stop using; open the lid to use.
I've been doing this routine since OS X 10.0.

Won't go to sleep or shut down

My iMac won't go to sleep or shut down when I tell it to. If I push the button on the back to make it go to sleep it doesn't do anything and if I select sleep from the apple menu it doesn't go to sleep. If I click shut down in the Apple menu it goes to a blue sreen and then the little loading symbol comes up and it just loads. I left it for an hour and it was still loading so I just held down the back button and turned it off that way. What can I do to resolve this?

First, try eliminating some variables-
Disconnect any devices attached via firewire or USB, and try again.
Some USB devices have been known to prevent the iMac from going to sleep or shutting down.

MacBook Pro won't Sleep or Shut Down

My MacBook Pro won't go to sleep or shut down.
Sleep
The behaviour is the same whether I press the power button and choose 'Sleep' or whether I choose 'Sleep' from the Apple menu. The computer stays awake, but it loses the ability to respond to Keyboard Shortcuts, such as those used for Expose, and can get stuck in some Apps. If I close the lid the computer stays awake but the screen blacks out. Re-openning the lid does not re-illuminate the screen so I have to force shut down and re-boot.
*Shut Down*
The behaviour is erratic. Sometimes the computer simply ignores me (although it does close the 'Are you sure you want to Shut Down now?' window), and sometimes it goes to the blue screen with the progress circle and hangs.
*What I've tried already*
- Resetting the SMC
- Checked the Firmware versions are the latest

Sorry for the repost. New to this forum and I hadn't seen the answers to the last time I brought up this topic here:
