QT opens when computer powers up?? later computer shuts down unexpectedly

I seem to remember this a while back when I installed a QT update that the computer would shut down unexpectedly and I had to reinstall QT. Does anyone else remember this? Sara

I just went in and changed to system preference for podcast updates to manual. It doesn't shut down now, but I guess I won't get my podcasts...

Black Macbook (Late 2006) shuts down unexpectedly when plugged in!

I have been having trouble with my Macbook shutting down unexpectedly for the past two weeks and got it checked out and it turned out it was the battery that needed replacement. So I'm using it without the battery but connected to the Magsafe adapter while my new battery gets mailed to me but suddenly it shuts down anyways! What could it be?

Hello Brine,
And welcome to Apple Discussions!
According to the Apple support document below, just bumping the A/C adaptor could cause the Macbook to disconnect and shutdown. Are you positive that this isn't happening?

Otherwise, you may just have to wait and see if the issue persists when the new battery arrives.

Try verifying the hard disk.
Boot from your restore disk while holding down the C key until you see the Apple logo, then let go of the C key. You'll see an Installation window, select English. From the Menu Bar, select Utilities/Disk Utility. Select MacintoshHD 10.x.x in the panel on the left, select the FirstAid tab, then click Verify. If DU reports errors, click Repair. If Disk Utility cannot repair the disk you have several options. One is DiskWarrior or
TechToolPro If Disk Utility can repair any errors, go back to the Menu Bar, click Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.
If you don't have a restore disk, try booting into Safe Mode

Macbook (Late 2009) Shuts down unexpectedly during boot

I have a late 2009 macbook that did not have any major issues until a couple of months ago, when it shut down randomly on me, and when I tried to reboot it, it would make a *click* noise and it would turn off without any signs of problem. I've tried resetting both the pram and smc, neither of which seemed to do anything. The farthest it's gotten into boot since is just barely into the log in screen, so any hopes of getting info off of it is pretty much gone.
Any help with this is greatly appreciated.

Hi there 74235,
If I understand correctly you are unable to successfully boot your Mac because it keeps turning itself off during the boot and is accompanied by a physical clicking sound, rather than a sound coming from the speakers. I would recommend these 2 steps from the following article to see if checking the disk in one of two ways will resolve or isolate the issue:
Resolve startup issues and perform disk maintenance with Disk Utility and fsck
Try Safe Mode
If you're using Mac OS X 10.2 or later, you can start up your computer in Safe Mode, which includes an automatic disk check and repair. If you're using Mac OS X 10.1.5 or earlier, skip to the next section. A Safe Boot, which starts up your computer into Safe Mode, might allow you to start up your computer successfully. To do this, follow these steps:
Start up in Safe Mode.
After the system has fully started up, restart your computer again normally.
If your Mac successfully restarts, the issue should be resolved. If the issue continues, try using Disk Utility.
Try Disk Utility
Use these steps to use the Disk Utility app to verify or repair a disk.
If you're using OS X Lion or later, start the computer from Recovery System or Internet Recovery. If you're using an older version of OS X and your computer came with a Mac OS X Install disc, insert the installation disc and restart the computer while holding the C key instead.
When your computer finishes starting up, choose Disk Utility from the Utilities window, or from the Installer menu if you're started from an installation disc.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Startup Disk (usually named "Macintosh HD").
Click Repair. Disk Utility checks and repairs the disk.
Tip: With Mac OS X v10.6 and earlier, always start up your computer from an Install or Restore disc when using Disk Utility to verify or repair your startup volume. Otherwise, you might see some disk error messages.
Thank you for using Apple Support Communities.
Take care,
Sterling

My Macbook Pro 15" (late 2007) shuts down unexpectedly

I have started having this problem intermittently over the past month, and it has gotten worse over the past two days.
I am using my Macbook Pro normally (watching Youtube videos or online streams primarily), and it will suddenly either go to sleep or shut down entirely. If it goes to sleep, I can press enter and it will wake up briefly before going back to sleep about 3 seconds later, until eventually it will just shut down on its own. If it shuts down completely, I can press the power button to start it back up, but it will shut down again before even reaching the login screen. I tried going into bootcamp, but it shut down before I could select the Windows partition.
The only thing that has worked so far is resetting the SMC by holding Shift+ctrl+alt+power button for a few seconds while it is off. That lets me start it up for a while, but if I ever start using it for something a bit more demanding (again, Youtube or video streams, for example), it will shut down after probably about 30 min. of use.
I just got back from the Apple store today to get my power adapter and my battery replaced. The power adapter cable connection was exposed, and the computer had been saying to service the battery for a couple of years now. After replacing those, the service battery message went away, but it just started shutting down again. The Apple store MRI diagnostics only showed the battery problem.
One other piece of info is that I hear a click from the left side of the laptop before it shuts down (can't tell if left front or left back).
Any help would be greatly appreciated. Thank you.

Why is my computer powering up automatically after shut-down?

My Power Mac G4 has mysteriously started to power up in the middle of the night and I can't figure out why? I am on high speed cable hook up and don't recall changing strat up functions. Any advice?

Hi, SoCal -
Resetting PRAM used to be (and sometimes still is, by "old-timers") called 'zapping' the PRAM. In olden times, like back in Mac Plus days, it was necessary to remove the battery to do it. In more modern machines it can be done via the startup keyboard command key combination of Command-Option-P-R.
PRAM retains various settings used by the Mac during startup - what monitor settings to use, clock info (time and date references), what boot volume and OS to use, and several other things. Sometimes PRAM values can get contaminated, damaged, or confused - and the Mac does not behave like it should.
Resetting PRAM reverts the settings in PRAM to default (factory original) settings. Doing this can clear whatever data corruption there may be in PRAM, forces the Mac to review what hardware is available and other configuration items, and, depending on model may (sometimes temporarily) reset some user settings (like date and time) to default values.
This can often cure some issues related to booting or resulting from changes in hardware.
There's a bit more info on that here -

My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them. The shadow of those opened documents are still there hours later after shutting down and restarting my computer. What is happening

My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them.
Even when I swipe to the dashboard the outlines are still there when I know they should not be.

What is happening and what shall I do? Thanks in advance.

I'm sure this is a setting fix, but can't find it-. All of my windows for mac programs open when I turn on my computer, such that I have to close each one individually to get to my desk top. How do I adjust so none of them open unless I choose to?

Which Mail icon? That in the Applications folder, that in the Dock, or some other? You do not have to quit your applications in order to shut down your computer (heck, you hardly ever need to shut down your computer).

My MAC mini looses the wi-fi connection to a Belkin N wireless router when it goes to sleep or shut down. I have to re select the network when restarting or waking the computer up. I think this just started with Lion. My iPod and iPad have no trouble.

Thank you BGreg. That is what I have been doing, and then it works just fine. I think it was doing the same thing in the previous version of Lion. I may be incorrect about that. I upgraded to 10.7.3 a few weeks ago, and then last week I reloaded the combo update, hoping it would help. Not so. Thank you for letting me know it is a common problem. I have tried permissions in Disk Utilities, and in Macaroni, both at least 4 times, plus numerous restarts. Nothing Improves. It still can not find the internet when it wakes up or gets up.

Computer shuts down unexpectedly during operations

My computer shuts down unexpectedly during operations. The unit will run for about 20 minutes and then suddenly shut down for no apparent reason. When I try to reboot the machine it comes on and shuts down immediately. I have to wait 30 minutes to an hour before I can use it again. I am running windows 2000 as my OS and my motherboard is a K7 prom AMD. Can anyone out there help me? I am going crazy trying to figure this thing out.

Hi, I have the same problem. When windows (XP) starts loading it shuts down and restarts alone; sometimes it passes and loads complete but then after a while it shuts down. With the error free load option it is more stable but it also shuts down alone. I tried everyting that is on my hands: changed the agp to a pci VGA board, eliminated all other boards, flashed the Bios, changed the power supply, checked the Hard Drive, changed RAM, etc., etc. My conclution is that it has some relation with the VGA display but in the bios; if you use more graphics it shuts down.
My system is a 694D Pro-AR (MS-6321) mother board with Pentium III 1GHz, 768 MB Ram, Matrox G450 Dual AGP.
