Sleep V. Shutdown?

I know this is probably a dumb question; but is there an advantages/disadvantages to putting it to sleep as opposed to shutting it down? If I'm done using it for the time being, should I shut it down or just put it to sleep?
Does shutting it down conserve battery?
Thanks

I thought if you were traveling with your macbook that shutting down is advised....for the safety of the drives. My understanding was that the HD is still engaged and the heads are not parked.
No, that's not true. When it sleeps the heads are parked.
I have traveled on cross-country (or intercontinental) flights where I slept the machine the entire way out and back, never shutting down until after getting home a week or more later. It's no problem at all and perfectly safe. It's actually better, because if airport security wants to see your laptop running, you don't have to sit there and wait for startup to complete, you simply open the lid and it lights up right away.
Sleep is really the only way to go unless you will not be using it for several days. With sleep you dont have to close down all the apps and documents you are using and open them all again when you start up. That saves so much time. I don't buy the "shut down saves energy" argument because a sleeping Mac laptop with a fully charged battery will not drain the battery for the better part of a week, maybe longer with the new extended runtime battery. That's how little energy sleep uses. It isn't significant.

G4 MacMini won't sleep or shutdown after update to 10.4.8

Since updating using software update to 10.4.8 on the logout screen I mostly used the "Sleep" option after logging out from my account. To begin with things seemed fine, but now, it won't go to sleep. If I click on the button to sleep the computer, the controls get greyed out for about 30 seconds to a minute, then return to their normal state - but the computer does not enter sleep mode.
Shutdown doesn't work either! I had to hold the power switch on the back down for a few seconds to force it to switch off. Interestingly, the internet connection light on the router was flashing irregularly while I was waiting for it to switch off.
I have reset the permissions (only after the install, not before), reset the PRAM, and searched the system preferences to see if something is glaringly obvious as being wrong but have found nothing and no have no further clue what I can do...
Is it related to my not wanting iTunes to provide Album Artwork at all? For some time, every time I opened iTunes it demanded I update my Album Artwork, but I don't want to and don't have an iTunes account. I had put off downloading both 10.4.8 and iTunes 7.0 for almost a week - until software update failed to provide a Cancel button for me to refuse again!
How can I get sleep and shutdown to work properly?
MacMini, PowerBook, PowerMac G5 DC Mac OS X (10.4.8) Mac OS X Server 10.4.8

Problem Solved!
I copied the combo update over the existing system but this alone changed nothing. Because I was unsure of which of my seemingly many OS X disks to load I rang Applecare (thank God I signed up for the three years of extra phone support - a real bargain) and they suggested I do a PMU reset - after which everything worked fine - so far.
They warned me about not doing a PMU reset very often (I guess the PMU can only stand a certain number of these events before breaking). In order to do one follow these steps:
1) Switch off computer;
2) Unplug ALL leads and power cables to the computer;
3) Wait ten seconds;
4) Simultaneously hold the power on button down while plugging the power cable in to your Mac;
5) Connect your other cables.
6) Switch on and go.
For me, this fixed all my other problems - Sleep, Restart, Shutdown, Printing, iSight, Internet connection speed, Quick Time performance, and so far I haven't seen anything else wrong to fix. Hopefully there won't be anything else to fix!
If anything does go wrong after this, I will do the Archive and Install, which was the next suggestion from Apple which I did not need to do. So far.
Thanks to all those who gave suggestions, I appreciate your help.
Thanks,
Mac

Which is better... Sleep or shutdown?

Which is better for your computer... sleep or shutdown?
Thanks

Technically, it doesn´t matter much if you shut your computer down or just put it to sleep., i.e. nothing is more detrimental to your computer´s "well-being" than the other, respectively.
I´m not sure about the Sleep Mode with the iMac, but I believe it´s a suspend-to-ram, right?
That would mean any unsaved data isn´t saved and could get lost if the computer fails to wake up from sleep.
That could be a point against making the computer sleep.
When it´s sleeping, the computer will also consume a steady, albeit very low quantity of electrical power. From an energy-saving standpoint, that could also be counted as a negative aspect.
MacBooks and MBPs use suspend-to-disk as sleep mode, which means the contents of the ram is saved onto the hard drive and then the computer is fully turned off. Takes a bit longer than suspend-to-ram.
I always put my computers to sleep... both my iBook G3 and my Win laptop.
My win laptop will automatically enter suspend-to-disk after 2 hours if it isn´t used again by then.

Sleep, Restart, Shutdown loop - how do I get out of this loop?

I installed os X Panther on mom's older iMac.
Tonight, when it's booted it comes up with "sleep, restart, shutdown" options.
We've selected each of these 3 items, waited, then either woke it up, waited for it to restart, or restarted it from shutdown; however, again it will eventually show a screen that only allows her to select "sleep, restart, shutdown"
How does she get out of this loop?
Note: There is not option to cancel the screen that has "sleep, restart, shutdown."

It shouldn't be necessary to reboot the computer to complete an update.<br />
Download a fresh copy of Firefox ([http://www.mozilla.com/firefox/all.html]) and do a reinstall of Firefox on top of the current version.<br />
You may need to do a clean install:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

MacBook Pro won't sleep or shutdown (intermittent problem)

Every so often my MacBook Pro won't sleep or shut down. I can't find any rhyme or reason to it.
I notice the problem when I close lid, and it doesn't go to sleep. I then hit apple menu:sleep, and it does nothing. I hit shutdown, and OS shuts down, but gets stuck at blue screen with spinning circle indefinitely. Have to hold power button for 5 seconds to finally shut down. Startup is then slow, but doesn't give me an error message indicating improper shutdown or failure.
Most of the time it sleeps fine and shuts down fine.
Other posts seemed to have the problem more reliably, and the fix had to do with startup items. Mine is intermittent, and the only items in my startup folder are Norton Antivirus and Parallels.

I am also experiencing the exact same problem you are describing. Completely random when the machine will not sleep or shutdown, although it seems to occur more often when I've had the machine running for a few days, moving between home and office locations.
I have VMWare Fusion and Office 2004 installed. No iStatPro. I'm wondering could it be related to the kernel extensions that VMWare and Parallels install? Is anybody experiencing the non-shutting-down problem who doesn't have either VMWare or Parallels installed?
I found the following section in my system.log file that occurred the last time the machine wouldn't shut down. May be of some use to somebody

Macbook pro will not sleep or shutdown

Help! My macbook restarts anytime I try to put it to sleep or shutdown. The only way is to do a hard shutdown.

Start by removing "Kaspersky," which is worse than useless and should be removed even if it's not causing the problem.
Remove "Kaspersky Security" by following the instructions on this page. If you have a different version of the product, the procedure may be different. The product includes a Safari extension that may not be removed by the uninstaller.

Power Key+S no longer sleeps computer (shutdown instead)

Hello,
I'm noticing something a little strange recently. When I hit the keyboard Power Key and the window comes up, pressing the S key will now shutdown the computer. For years I've used the to sleep my computer, and now it's not working. Any ideas on what might cause this, or how I can fix it? Thanks.

I guess I don't see how this is a problem with the keyboard/driver. Isn't that Sleep/Restart/Shutdown window the same one that comes up with a traditional mac keyboard? Wouldn't the S key do the same thing there as well?
maybe you are right but I would still check the keyboard first. bad keyboard drivers can make a keyboard behave in a very unpredictable fashion. do you have access to another keyboard? a mac one? that would b best for testing.

Sleep and Shutdown issues after upgrading to Windows 10

Hi there,So I'm having issues with sleep and shutdown after I upgraded to Windows 10, the laptop won't go to sleep or shutdown properly. The screen turns off, but the power LED stays on and the fan as well. If I chose sleep it won't wake up no matter what I try, and I'd have to perform a hard shutdown everytime.Any solution for this problem?Thanks.

**I have posted this in another area with the same issue** YES!!!!! A Solution that worked. Spread the news. It has to do with the Intel Virtualization Tehnology. Didn't know what that was until this issue came up in Windows 10. First, find out if this is your issue. 1. I installed the 'Intel Processor Identification Utility' directly from Intel.2. After installation, open the program and go to the 'CPU Technologies' tab.3. If it says 'YES' for Intel Virtualization Tehnology, proceed. Solution...(at least on my system) 1. The next thing you have to do is go into the BIOS. If you have not done this before, proceed at your own risk. You need to restart the computer and enter the BIOS (for me I hit F10 at the HP screen)2. Within the BIOS, there is an 'Advanced Options' section3. In this section there is a line for 'Intel Virtualization Tehnology' and it will say enabled or disabled. My computer said disabled.4. If this is the case, change the option to 'ENABLED'; then SAVE and EXIT from the BIOS. The Computer will restart and from that point on Shut Down, Sleep, etc. has worked. WOW this was a frustrating issue. Almost went back to Windos 8. I take no credit for this solution, I pieced it together from other posts on this issue. Hope this helps.

A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--
(username is your name or System Administrators name)
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.7 Combo update. Others reading, download the combo update that applies to you!
Cheers!

My HP Split x2 cannot go to sleep or shutdown, keep waking up by itself

My HP Split x2 recently cannot go to sleep or shutdown. It will sleep / shutdown for a few second and wake up by itself until battery died.
Anyone having the same issue?
Seems that HP is not reliable because beside this I also have pointer freeze and SD Card slot that cannot read SD Card (can't even spring out the SD card out properly).
I will not buy HP device anymore !!!

Hey @Rayzng ,
Welcome to the HP forums.
I understand you're experiencing issues with your Split x2 notebook not going to sleep, freezing, and the SD card reader not working.
The sleep issue should be pretty easy to figure out. On your PC, open an elevated command prompt window and type the following command: powercfg -requests
Press enter and it should show you any display, system, awaymode, execution, or perfboost settings/drivers/programs that are affecting sleep settings.
Let me know what shows up in the results and we can go from there.
For the SD slot, I need to know your exact model. For information on finding your product or model number click here: Finding Your HP Product Model Number.
For the freezing, the general steps to take include updating drivers and BIOS. Main drivers to focus on should be the display adapter, wireless adapter, and chipset. Drivers can be downloaded by entering your product info here: HP - Drivers & Downloads.
This should get us started. I look forward to hearing back from you.
Thanks!

X201s not properly going to sleep / hibernate / shutdown mode and instead gets piping hot

My 3.5 year old X201s that has been working like a charm has developed a nasty problem:
None of the "normal" methods to get the system to "turn off" seems to be working any longer. The OS (Win7Pro-32bit) does its normal thing during sleep / hibernate / shutdown, the screen eventually goes blank but the system never goes into the appropriate powered down state. The area under the CPU becomes hot and the system is totally unresponsive to Fn button, mouse button, lid opening, power button press.
More specifically:
"Start->Shutdown" or single Power button press results in battery LED solidly lit, no "beep". Systemis unresponsive to subsequent normal power on.
"Fn+F4 Sleep" or Close Lid results in Battery and Moon LED solidly lit, single "beep". System is unresponsive to any subsequent normal wakeup attempts.
"Fn+F4 Hibernate" results in Battery and Power and LED solidly lit, moon blinking, no "beep". System is unresponsive to any subsequent normal wakeup attempts.
In all cases, I have to press and hold the power button for 5 sec (at which point all LEDs turn off as they should) to then be able to normally boot the system again. Upon booting, Windows does not complain of any improper shutdown and boots normally from scratch (sleep/shutdown scenario) and in the hibernate scenario, resumes properly.
I have the latest BIOS and Thinkvantage updates installed, have turned off Blutooth, disabled "always-on USB" , have also uninstalled Thinkvantage Power Manager but have not seen any change.
Reading some of the other threads on here about aging thermal paste and hot running CPUs, could this have fried some of my Power management circuitry?
Could an overheated
Any insight would be much appreciated!

Some follow-up:
- I applied the Intel ME firmware update 6.1.32.1076, see
http://support.lenovo.com/en_US/detail.page?LegacyDocID=MIGR-77175
but this did not fix anything.
- Reinstalled latest Lenovo Power Manager and driver, - no luck.
- Recovered original factory image, - still the same ill-behavior.
Has anyone had experience with sending out of warranty laptops to Lenovo for repair (likely motherboard replacement)?

The restart/sleep/cancel/shutdown menu shows up all the time.

We have one of the newest imacs (beveled back), and it has started automatically asking if we want to restart/sleep/cancel/shutdown as if we had pressed the on/off button. If I hit cancel it comes back up again shortly thereafter.
Is it a faulty on/off button that need to go in for repair?

You should really use the Apple dropdown menu to select Sleep, Restart or Shutdown instead of using the power button.
To "Allow the power button to put the computer to sleep" Go to: Apple > System Preferences > Energy Saver and check the box "Allow the power button to put the computer to sleep"
Noting that: the power button should only be used to shutdown an iMac, if it is totally unresponsive.

What is better for a fast MBP sleep or shutdown

Hi
is it okay to shutdown the computer instead of sleep like 4 time in 24 hours?
I would like to know what's best for the MBP. because I shut it down like once every three days or so. But when I leave it sleeping a lot of times I come and find it dead and needs to be plugged. So I'm thinking of shutting it down more often to save the battery.
what do you think?
P.S. running Lion OS X 10.7.2

If the computer will not be used for more than 8 hours then it would be better to shut it down and save power. Otherwise, use sleep. However, if you will leave the computer near an AC outlet then connect the AC adaptor. Use the battery when you cannot connect to an AC outlet.

MBP Sleep or Shutdown which should I be choosing?

I recently read a section of the book OSX Missing Manual and it mentioned that cycling a Macs power was rarely required. Being a recent convert from the world of Windows I have always powered off my laptop at the end of the day and powered it on again when needed and I have been doing the same with my MBP.
Is it really advisable to put my MBP to sleep rather than shutting down even if I will be transporting the MBP to and from the office?

A couple of things to consider:
1) Regardless of how great OS X is there are memory leaks and problems with apps. Eventually a reboot is a good thing. But OS X is great that way in that it will run for weeks before a reboot might even help.
2) For me I go from just a laptop at home to plugging in a 20" Dell flat screen and a keyboard/mouse at work. My MacBookPro doesn't always wake up from sleep nicely in this configuration. Sometimes it has presented me with a blue screen but no log in prompt. One time I even had to power down then reboot to get anywhere. I've never had this happen just as a laptop waking from sleep.
3) If you plan to travel on an airplane I would HIGHLY recommend a shutdown. Here is way. Most airplane cabins are pressurized and present no problems to humans or computers. However a friend of mine was on a flight that experienced pressurization difficulties. For a short time the cabin rose to almost 10,000 feet before the pilots got it under control. Several elderly people passed out etc. His Window XP laptop had just been put to sleep but something woke it up and started the disk spinning. Disk heads are designed to "fly" over the disk on a micro-cushon of air. At 10,000 feet the air was too thin and the head could not fly. It scraped the disk and tore the heads off the drive. (Rare occurance yes... Do I recommend not using a laptop on a plane while in flight, absolutely not, but when you are done shut it down that way you know for sure your disk is not spinning accidentally while you are boarding, loading and unloading).
This is also a warning for private pilots. I fly regularly and most aircraft I have access to will do 12,000 to 15,000 feet but are not pressurized so I carry O2. But I had a girl along for a ride from Fort Collins to Wenatchee Washington one time who at 12,000 feet was bored and wanted to use her laptop. I caught her just in time before she ran the risk of destroying it.
Anyway these are just my thoughts. I love the concept of sleep but sort of don't trust it fully. That's probably my Windows paranoia coming out.

OS X 10.6.3 update delays Sleep and Shutdown execution

Hi,
I updated my mac mini (Late 2009) after a lot of apprehension to the latest 10.6.3 version and find that "sleep" execution has increased from almost instantaneous on 10.6.2 to almost 34 seconds. Shutdown execution has increased from a quick 4 seconds to 36 seconds, boot time has also increased from 32 to 36 seconds. Will someone at Apple please look into this and release a patch - this is most irritating - upgrades are supposed to improve performance and not degrade it.
Can any user upgrading to 10.6.3 confirm these time delays please. Thanks you.

Sorry, I wrote iMac above. I forgot which forum I was in!
When I see that there is something vital, such as a upgrade to Mac OS X or a Security update, I decline allowing SU to do the installation. Then I go to the Apple Downloads page and manually download and apply the update/upgrade. If it is an OS update, I download the larger Combo version. Before I manually install the updates I first shut down all other processes and then use Disk Utility to repair the disk permissions. (Actually, I repair the disk permissions before and after the installation.) I also Verify the disk and if there are issues found, I boot from the install DVD and use Disk Utility in the Installer's Utilities menu to repair the disk. Then I install the update.
To reset the PRAM (re)start your Mac and immediately press & hold, all at the same time, the CommandOption+PR keys until you have heard the startup chime for a second time, then release all of the keys and allow the Mac to boot.
To reset the SMC;
• Shut down your Mac.
• Detach the power cord from the rear of the Mac mini.
• Press and hold the power button for 5 seconds.
• Release the power button.
• Attach the computer's power cable.
• Turn on the computer.
Also repair the disk permissions. Another thing you might try is getting a copy of OnyX and letting it clear out your caches on occasion.

Retina Macbook Pro will not sleep or shutdown, and reboots randomly

My 15" RMBP will not shutdown or sleep and sometimes will restart randomly or restart when it is commanded to sleep. Forcing it to shutdown by holding down the power key is the only way to shut it off. It does this when I've created a new user. I've tried quitting processes, have run ClamXav, have tried to reset the SMC. It has displayed this type of behavior since I bought it in the summer of 2012, but lately it has become much worse, (refusing to shutdown is new). Is anyone else having the same problem or can suggest a solution?
thank you very much
