I don't think my computer is completely shutting down. I think it is only going into sleep mode. When I hit the power button, it turns off immediately instead of shutting down.

I don't think my Mac Pro is completely shutting down. When I hit the power button, it just turns off immediately instead of going through the normal shut down procedures. I heard that I should try resetting the SMC, which involves removing the power cord. However, when I remove and replace the power cord, it turns on automatically, so I can't even properly reset that to see if it is the issue. Is this probably a power supply issue?
Actually, in case this information helps... The computer went into sleep mode the other day, and would not come back. This is a work computer that I use for our photography business, and at this point I am just trying to run it as a drive to get the photos onto our new computer, but this issue is keeping us from doing so. Any help would be greatly appreciated!

Try a SMC reset.

Are the lines like psychedelic herringbone? If yes, I had that happen once, it was something serious, like the
Logic board. The good news is that it was fixed without any loss of data on the hard drive. Take it in to have Apple look at it ASAP. I took it to TekServe at the time, they are very nice about preserving your data and user library when possible.
Good luck and don't panic.

I am running OSX Lion 10.7.4 and the computer no longer will go into sleep mode when I close the cover What happened with this option?

I am running OSX Lion 10.78.4 and the computer will no longer go into sleep mode when I close the cover. In system preferences I can no longer find the option that allows for this energy saving feature. What happened to this option and why is this no longer happening with the latest version of Lion?

No external monitors or devices attached. When you mention that this function only works when devices are attached that is true when you set up your preferences that way. Up until my upgrade to Lion the computer would always go into sleep mode when I closed the lid. There also used to be an option to check in system preferences that allowed you to choose this option. My question for the discussion is what happened to that option and how do you get the computer to sleep or at least the display to sleep when you close the lid as we have been able to do in the past. Thanks.

Computer Goes Into Sleep Mode By Itself

Experiencing a weird phenomenon this morning... my PowerBook is sending itself into sleep mode. The battery is charged and it's not overheated. It does it when plugged in and when unplugged.
When I hit the 'power' button to wake it up, it always comes back on, but then shuts off 10-30 seconds later. It's now been on without sleeping for ten minutes or so, but would still like to know what's causing this very un-Mac-like behavior and how to fix it.
Thanks,
Matthew
PowerBook G4 15" Mac OS X (10.3.9) 100G Hard Drive

Back to the beginning, then. Are you certain the Powerbook is actually sleeping? Is the sleep light pulsing? If not, the problem is that your backlight is going off, not that the PB is going to sleep. That would most likely indicate a bad inverter board. When the backlight goes off, shine a bright light on the screen, or shine a bright light through the Apple logo from the back side of the display. Can you see the screen image that way? If so, replacing your inverter will probably solve the problem — and if the inverter is failing, nothing else will.
EDIT: BTW, I meant to mention this earlier but forgot. In your original post you implied that you habitually hit the Power button to wake the computer from sleep. That's probably not a great idea, since there's a small risk that you'll accidentally shut it down that way if you aren't really paying attention. I always wake mine using a Shift key, which carries no risk at all of causing anything odd to happen — not even of typing a stray character into an open document, or moving the cursor from where I left it.

I did a factory reset on my late 2008 MacBook from a Snow Leopard disc. It installed fine, but as soon as I began to use the computer (safari) it froze. Couldn't even force quit. So I held down the power button to turn it off, and now it won't start up.

So I held down the power button to turn it off, and now it won't start up. It goes to the grey Apple screen and just sits there loud as can be. Help! Please keep in mind I've not done anything like this before and am going to need a little hand-holding. Thanks in advance.

Hi. Don't worry it's nothing serious. Insert the Instal Disc (Snow Leopard) and press the C button while turning on the computer. Once you see the desktop, go to Utility and choose Disk Utility. Select the Macintosh Partition on the left window pane and then click on Repair Disk and Repair Disk Permissions on the bottom right corner. Wait for both processes to finish. Click on the Apple icon (top left corner) and choose quit. Your computer should restart. See if it reboots normally. If not you can always reinstall the OS following the same steps. Good luck!

I have a mid-2011 iMac running Mavericks. When I click restart the computer goes to a white screen with a spinning circle and does not go any further until I hold down the power button to turn it off. What do I do?

Ok, sounds like the safe mode boot worked... You probably don't want to always be in safe mode though (some reduced functionality) so does it do a normal boot now? If not, you should then reboot into safe mode and run Disk Utility. Then select Macintosh HD on the left hand side, and click the Verify Disk button. If needed, it will ask you to Repair Disk. If there are errors found, Repair Disk again until there are none. Then try another normal boot and reply with result, wether good or bad.

My computer shuts down after 45 seconds from when I push the power button. Anyone have an idea why?

After pushing and holding the power button on my Mac the apple screen comes on and after a few seconds there is a loading bar that tries to load something for a few seconds then it shuts down. I would say it is approximately 45-50 seconds after pushing the power button. Power comes on then shuts right off. This all originated when I tries to log in as a different user. It froze for a while, then I shut down the computer with the power button. Because I couldn't so it from the apple icon on the desk top

Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, 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 at top of the screen. (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. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive & clear caches.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Apple tv loses home sharing when my computer goes into sleep mode

Just recently, my Apple TV says that home sharing is off when my computer goes into sleep mode. It never used to do that - any suggestions?

I have the same problem here. Always back-ed up with Time Machine (OSX 10.9 Mavericks) to Western Digital drives. MyBooks, MyPassport 1TB (USB 3.0), all works fine. Time Machine is actually doing back-ups overnight. Since I got this new 2TB MyPassport Ultra USB 3.0 it's working perfect during days, but every morning when I wake up the MacBook from sleep, I get this annoying error:
Time Machine couldn’t complete the backup to “MyPassportUltra”.
Unable to complete backup. An error occurred while creating the backup folder.
Latest successful backup: Today, 02:27 am
I'm also not able to write anything to that drive, or unmount it. It stil shows up in Finder, and I'm able to read all the data perfectly fine. When I do a Disk Utility Verify Disk directly after, I get this:
Checking volume
disk3s2: Scan for Volume Headers
Invalid Volume Header @ 0: I/O error
Invalid Volume Header @ 2000021315072: I/O error
disk3s2 is not a CoreStorage volume
Error: This disk needs to be repaired. Click Repair Disk.
I don't click Repair Disk, as this will probably screw up my partition. Instead, I have to unplug the USB cable (which is bad for the drive, there's no time to park the drive's heads) and plug it in again. After clicking Backup Now, Time Machine immediately starts backing up, and the drive works fine the rest of the day.
I contacted WD Support, and they are sending me a booster USB cable. As System Information reports, the drive receives enough power though:
Current Available (mA): 900
Current Required (mA): 224
Unfortunately there's no firmware update for this drive, which will probably fix this. See this topic: https://discussions.apple.com/thread/4196704.

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

HP Envy shutting down after going into sleep mode

Hi. I'm not sure where to post this so I'll try it here.
My laptop shut downs automatically when it goes into sleep mode. Not right away when going into sleep mode. Maybe like an hour later after going into sleep mode.
I'm not sure it's overheating because it never shuts down while I'm actually using the laptop.
Do you guy have any idea how to fix this?
Product name and number: HP ENVY TouchSmart Sleekbook 4-1115dx

Do you know which iMac model family you have? There are four families dating back to 1998. Troubleshooting depends on that. This forum covers the first three families made from 1998 to 2005. iMacs newer than that get a separate forum.
Do you have the system disks that came with the computer? If so, and depending on model, you may be able to start from the CD/DVD and then make the jump to booting normally.
All computers has a little battery on the logic board that holds date, time, and some important startup parameters when the compuer is taken off wall power for a short time. If your battery was very old and died, then the settings the computer needs to start may have been lost when you unplugged it. For some Mac modles, booting from a CD or DVD gets around this temporarily, but ultimately the battery needs to be replaced. The internal batteries are cheap but can be hard to access on some iMacs like the G4 "desklamp" model

The Cannot Setup Sync message indicates that you don't have internet access. Check that you can get your phone online (3g or wifi) and then try to connect again.

Late 2012 Mac mini with OSX 10.8.2 has started shutting down instead of going into sleep mode.

Sometime in the last week or so my mac mini has started going into full shut down instead of sleep mode.
I have tried checking and unchecking energy saver boxes but haven't found anything which will get me back to where I used to be - and I haven't knowingly changed anything to make this happen.- maybe an OS update caused it?
The machine will fire up with a tablet click rather than needing the reset button to be pushed so clearly the machine is sort of halfway between sleep and full 'off'. Most frustrating as one of the key issues for me in getting this my first mac was its easy sleep and super quick fire up compared to windows.
Any help appreciated
Oh yes I just remembered that I did just install 2 8gb of crucial RAM (to replace the supplied 2 2gb but surely that can't have anything to do with it - can it)?

Adding to my first post I can now advise that when the mac goes into sleep mode the light on the front stays on (it does not pulse so clearly it is not really sleeping).
When i click the tablet / keyboard this is actually what triggers the mac to reboot
I have tried resetting the SMC as per the following link to no avail
http://macs.about.com/od/usingyourmac/qt/Resetting-The-Smc-System-Management-Con troller-On-Your-Mac.htm
Help please!

I don't think my computer is completely shutting down. I think it is only going into sleep mode. When I hit the power button, it turns off immediately instead of shutting down.
