My ~4 yr old MacBook restarts whenever I tell it to shut down and won't properly go to sleep.

It will only shut down if I hold the power button. Late 2009 MacBook running 10.6.8. It does this in Safe Mode, I've done an SMC reset, the extended hardware test (no problems), and it doesn't seem to be connected to any particular application being opened or amount of time the computer was in use. Has anyone been able to fix this problem? I've seen a lot of forum posts with no solution.

Take the machine into your local Apple Store or an AASP and have them fix it.
I had a similar issue when I was syncing a friend's iPhone (I don't own one) in that the machine shut down when the iPhone was plugged in. But I was able to reboot. A lot of people seems to have the problem that you describe, however.

Unfortunately do not know the operating system since I never updated anything and I can't get in to it.
Thanks for your assistance.

If you want to preserve the data on the boot drive, and it's not already backed up, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data, you can skip this step.
There are several ways to back up a Mac that is not fully functional. You need an external hard drive to hold the backup data.
1. Boot from the Recovery partition or from a local Time Machine backup volume (option key at startup.) Launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
2. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
3. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.

This can happen with faulty battery. Make Genius reservation and take iPhone to Apple Store for free quick battery diagnostic testing.

MacBook randomly shut down, and won't turn back on

First of all, hello. Secondly, I've got a problem with my MacBook: about half an hour ago, it randomly shut down and when I tried to turn it back on, it didn't. Instead, the backlight kept flickering at the tempo that something inside the computer was "clicking", and the longer I held the power button, the more "clicks" there were. Needless to say, I've tried charging the battery, resetting the SMC, and to no avail: I still can't power it up, even when I don't use my battery. Whether I use it or not, the MacBook still "clicks" during my pressing of the power button and stops "clicking" when I release it. My MacBook is a year old. Can someone help me out here?

Me too. Any resolution? I don't want to take it to my local apple place because they're retards, but according to the info on my warranty that's the only place available. Can't believe they don't have an RMA service direct to Cupertino, what a joke.

My computer randomly shuts down and won't restart.

My computer randomly shut down and would not restart. I took it to an apple store and they fixed it by running something through the disk utility. I was told to run something else (it had to do with what the computer does when it shuts down as I don't shut mine down a lot). It had been running when the guy showed me it at the upper right corner and said "initializing" but I did not remember what it was called when I got home and it was no longer open. Any one have a similar problem where this was suggested and remembers what is it called?

Try a SMC reset.

G5 shuts down and won't restart when set to sleep

Twice in a row this has happened to me. I press the power button on the back of my G5 for the required duration to tell the computer to "sleep" and sleep it does - for a few minutes. Then next thing I know it has shut down and become totally unresponsive and no amount or combination of unplugging and repluging the AC supply and/or holding down the power button for up to a minute can force it to respond in any way nor restart.
The solution is to disconnect everything; remove the back of the G5 and press the reset button on the logic board - but sometimes the comuter will just randomly restart all on its own when powered up with its back off.
Can anyone suggest what might be going on here and whether it is a software or a hardware issue.

Hi, Michael.
This sounds like hardware to me. Here's my list of general troubleshooting steps specific to the iMac G5 (you may have already seen #3, but it's included as it's part of my standard list):
1. The first thing I would suggest is ruling out potential hardware problems. Run the Apple Hardware Test that came with the computer. Instructions for doing so will be found in the hardcopy manual that accompanied your computer.
2. Check the diagnostic LEDs, a feature of your iMac G5. See "About the iMac G5 diagnostic LEDs."
3. If your iMac G5 will not turn on, see "iMac G5: Troubleshooting when your computer won't turn on."
4. See also the new iMac G5 Support site.
5. Check the iMac G5 Discussions for similar reports from other users.
6. As a general check, run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified. In your situation, I'd consider it a long shot, but it will determine if there are any issues with some "common troublemakers."
7. If the computer is either under warranty or covered by an AppleCare Protection Plan, don't hesitate to take advantage of your warranty and contact AppleCare.
Good luck!

Macbook Pro shut down and won't restart

Hi all
My Macbook Pro is just over one year old so now out of warranty. It just shut down without warning a few weeks ago (nothing strange happened, no water spillage or anything like that) and wouldn't turn back on. When I attached the charger to it there was no little light (either green or orange) and would just do nothing at all. I took it to an authorized Apple technicians (I live in Dubai) and they reset the motherboard and it was working fine. Last week it did exactly the same thing and shut down again and wouldn't turn back on. They're now saying they may need to replace the whole motherboard which is going to cost me a fair bit.
I'm quite annoyed as it is my first Macbook Pro and everybody told me how they never have problems etc etc. Any other suggestions as to what might be the issue or do I just need to shell out for the motherboard? I'd read online that the battery could be the issue but they're saying they tried a new battery in another customer's machine and it didn't work so are replacing the motherboard.
Thanks,
Lauren

It is difficult for anyone to ***** the problems your MBP is experiencing in a setting such as this forum. The best I can do is point you to this troubleshooting article;

800Mhz g3 12" ibook shuts down and won't restart

I have a 12" ibook that started shutting down on its own then that stopped but now at random i'll shut it down and it won't restart. I reset the PMU with no change. If i let it sit for about a week or two it will turn back on and run fine for a while again. Does anyone have any suggestions on what to check?
Thanks

It is not unusual for an iBook with the known _logic board problem_ to start up from time to time, but not reliably.
It sounds as though that is probably the problem.
After leaving it sit overnight, does squeezing the case to the left of the trackpad allow you to start up and work for a bit as long as you keep the pressure on it there? If so, you may want to consider trying the shim fix suggested by John Sawyer in the Apple Discussions iBook G3 (Dual USB) Displays Forum:
[Y]ou can often fix this yourself by removing the iBook's bottom housing, and placing a shim of any sort, about 1mm to 1.5mm thick, onto the raised square on the bottom shield. I use a Scotch mounting square--you can get them in hardware stores and many grocery stores. When you reinstall the bottom case, it will press against this shim, which will press against the graphics chip, and may allow the chip to come into better contact with the logic board.
John Sawyer
CJS Macintosh Repair
Instructions for removing the lower case:
iFixit.com
If the shim fix doesn't work (or you're leery of trying it), DT&T Services in Fremont, California offers one of the cheapest repairs I've found. They have a six-month warranty on the repair.
Once you get it fixed, try never to pick it up by the left front corner alone. The theory is that picking it up by the left front corner alone can contribute to logic board failure when the case flexes, causing the graphics chip to come loose from the logic board. If you're picking it up in your left hand (as I often do mine), pick it up in the center under the trackpad.
If you can afford it, the money may be better spent by putting it toward a new (or used) MacBook. I really love mine. It is a spectacular upgrade over the iBook G3, provided that you don't need OS 9 for anything.
Good luck with whatever course of action you decide upon.

MacBook Pro shut down and won't turn on

Hi, my laptop (only a month old) said it needed to restart in order to finish updating OS X, leaving it briefly I went into the kitchen and when I came back I watched as the screen appeared to be going into sleeping mode but upon closer inspection it turned itself off. Now even though it was 100% charged and plugged in won't turn back on. If anyone has tips would be much appreciated, it is the beginning of the week and I won't be able to get to a mac store until the weekend due to my classes.
Thanks

Ensure the mac is plugged in.
Hold the power button down and keep it pressed down while you count to 10, then release.
Press the power button once and immediately release. The mac should not start to boot up as normal.

Hi everyone, so I was on my MacBook Pro 10 mins ago and it all of a sudden shut down and won't turn back on? I haven't had it backed up for a while now but does anyone know what could have possibly happened and if it will affect my hard drive?

My MacBook Pro 13inch won't turn on? It randomly shut down itself and won't turn on!!? Will it affect my back up? Hard drive disk? Because it has all my work and personal things I really need on there! Please if anyone can help me!!

My MacBook suddenly shut down and won't turn back on - how do I get it to turn back on?

My MacBook suddenly shut down after freezing up and I cannot get it to turn back on again. I tried the suggestions in the manual and none of them worked to turn it back on. Is there something I am not doing correctly? The little green light on the charger connector is green but not as bright as normal, it was charged by over 70% before it shut down, so I do not think it is a battery problem. Is there anything I can do to turn it back on? Thank you for any help given, I really appreciate it.

If it won't bong, then try an SMC reset.

MacBook Pro freezes after clicking 'Shut Down' and won't remember 9600M GT

After choosing 'Shut Down' from the Apple menu my MacBook Pro (1998, 5,1 2.4 Ghz Intel Core 2 Duo) freezes and the Grey Screen of Death appears.
Strangely this only happens when I'm using the lower-power GeForce 9400M graphics card. When I use the high-performance NVIDIA GeForce 9600M GT graphics card my MacBook Pro wil shut down normally.
Ever since upgrading my system to Mac OS X 10.6.3 this problem occurs. But since then also other problems arose. After installing Safari 5 my MacBook didn't boot, and I had to zap the PRAM to get the system booting again. Since then my system won't save the 9600M GT setting in the Energy Saving panel. I can logout from the 9600M and login to the 9600M GT, but after a reboot it switches back to the 9600M card.
Today I did a combo update to Mac OS X 10.6.4, but all the problems still occur. Also I did maintenance tasks with 'Cocktail' and 'Maintenance', but that didn't help either.
Also sometimes after choosing the GeForce 9600M GT graphics card, OS X logs out and hangs in the blue screen instead of displaying the login screen.
I hope someone can help me out with this!

Unfortunately the problem reoccured, alltought less. The last weeks my MacBook froze two times.
The report I send to Apple contains the following:
... Sat Jul 17 12:42:23 2010
panic(cpu 1 caller 0x124fc5b): "AGC GPU REGISTER RESTORE FAILED : rdar://7254528"@/SourceCache/AppleGraphicsControl/AppleGraphicsControl-2.8.63/k ext/AGCPowerManagement.cpp:849
Backtrace (CPU 1), Frame : Return Address (4 potential args on stack)...
Anyone a clue how to solve this problem? Thanks!

Macbook Pro retina shut down and won't start

Someone help!
I was using my Macbook Pro Retina that I got in 2012 while I was on a trip in Tokyo, Japan. While uploading pictures from my camera, I left to take a shower and came back to see that my computer was shut off. I thought it went into sleep mode so I kept pressing the keyboard but there was nothing. I did have it plugged into the wall without an adapter. I tried the startup button and nothing. I came back to the States and went to the apple store. They said they don't guaranteed that my data could be recovered. I didn't want to take a chance because I'm too nervous I will lose all my files especially recent ones I haven't backed up yet. They suggested I take it to an authorized apple store to see if they could do a data recovery but before I go, does anyone have any suggestion on what I should do before I spend my money? I don't know if it's because I didn't use an adapter in Japan (100v) but I know it's universal. My iphone was charged every night and had no problem.
Thanks!!

btipparat,
the Apple store which you took your MacBook Pro to isn’t an authorized Apple store? Your MacBook Pro’s AC adapter supports worldwide voltages, 100 V to 240 V, so that isn’t an issue.
If you press the button next to the battery indicator lights, do they light up? Do they do so whether or not the AC charger is connected?

MacBook Pro shuts down and won't turn on

Hi r,
Is it running very hot, as in, could this be a thermal shutdown? Download iStat Pro if you don't already have it.

IMac Shuts Down and Won't Restart for ANYTHING!

I'm unsure if this is the right place, but our iMac just crashed for the second time. Here are some details:
1. It's happened before, but it was easily corrected when we switched power outlets. And even then the old outlet worked afterwards.
2. I've looked all over for help, but all I keep seeing is reports of the same thing - which is highly annoying.
3. I've tried all the soulutions I've seen:
~Shut down for 20 seconds, remove power cord, plug back in, turn on (didn't work), hold D.
~Take out RAM modules and put back in
I got a response from the latter "solution", but it didn't go past the start up whir, but not the start up sound.
It's not turning on for anything, what the heck do I do now?!
• January 2009 Mac (21")
• 4GB RAM
• 1 TB HD
• Good power source
• EXPENSIVE!
And those were the details on our actual Mac.
Please help!

This is the formal procedure for doing an SMC reset (disconnecting from power and reconnecting)
http://support.apple.com/kb/HT3964
so be sure you followed it precisely, instead of just unplugging it. Also, while doing this procedure, you should disconnect ALL cables. If you have been using a crowded or old power strip, connect it directly to the wall outlet, at least initially for this test. Power it up with nothing connected except for the power cord. If it starts up properly, connect just your keyboard/mouse and use it that way for a while. If the iMac is working properly at this point, you should also reset PRAM
http://support.apple.com/kb/HT1379
If all is well, add you peripheral devices back, one at a time if possible. If the problem recurs at some point, note which device was added last. USB and FireWire devices can become defective, or otherwise interfere with sleep, wake, startup, and shutdown.
If the problem still occurs, even after the SMC reset when you power up with nothing connected (except the power cord) or when you are using it with ONLY your keyboard/mouse connected, you should have it looked at by a technician at an Apple Store or Apple-certified repair shop. If you got it January 2009, it is still under the one-year warranty.

My ~4 yr old MacBook restarts whenever I tell it to shut down and won't properly go to sleep.
