Fan noise on startup AND shutting down

The last week my ibook g4 started shutting down randomly. The screen goes blue and the computer is unresponsive. I hold the power button down for several seconds and I hear it shut down. At the same time, intermittently - but most of the time now - when I start it up, I get the fan blowing - can feel the breeze out the back. It won't do anything other than that. When this happens I can't even shut the fan off - even by holding down the power button. I have to unplug the adapter and take the battery out to shut it off. After I do this 5 or 6 times it will start normally and work for about 10 minutes, then it shuts down again. Any ideas ? Thanks..

That seems really cheap....most others with logic board failures report the cost to be around $800 for repairs. Are you sure it was the logic board that failed?
And to all the others with problems similar to John's, you really should follow the advice he did and call AppleCare/Go to an Apple store for this type of issue! And good luck!

Need to make automatic startup and shut down for the instance

hi to all
i have os : Red Hat lunix as 3 , woth oracle DB 10g 10.0.1
need to make an automatic startup and shut down for the instance when i start and shutdown the OS
i tried Use dbstart and dbshut scripts then created file dbora at dbora as a script
then i did

nothing worked
if you will attach me any files
my mail is :

thanks much

Hi,
The /etc/oratab should have an entry for this database with 'Y' in the last field as:
Oracle_sid: Oracle_Home:Y, so when dbstart command issued it will check the oratab and starts the database.
I advise you to keep the dbstart and dbshut in different scripts and save them directly in the runlevel directories, instead of creating links.
thanks

I installed Canon software on my macpro laptop and it takes forever to startup and shut down

Hello. I recently got a Canon Rebel T3 and in order to download photos to my macbook pro I had to install their software. Well, after installing it, it takes VERY long to shut down and start up my laptop. Can someone help? I already deleted the software off the laptop, but that hasn't seem to fix the issue.

"... I already deleted the software off the laptop, but that hasn't seem to fix the issue."
I doubt that the software was the issue. So why not tell us what model MBP you have and how much free space is on the hard drive. When was the last time you booted to the OS installer disk and run Repair Disk from Disk Utility? BTW, you may not need their software to download pictures to your Mac. Launch iPhoto and from the menu: iPhoto>Preferences>General: Connecting Camera Opens.....

Startup and shut down problems with Nano

I am wondering if there are any preferences or settings I can change to prevent the following annoying problems:
1. The Nano starts up on its own when jostled around in a bag with other items. Sometimes it will actually start playing and shuffling songs via the built-in speaker and drain the battery.
2. The Nano is sometimes difficult to shut down: while holding the shut-off button at the bottom of the wheel, a menu drops down asking if I want to add the current song to "on-the-go." I am then forced to scroll up the menu to choose "cancel" and try to shut down again. Sometimes this irritating occurrence repeats itself over and over. Whatever "on-the-go" is, I would rather disable it than have this keep happening.

The Hold button is on the top of the iPod Nano not on the scroll wheel = iPod Nano 5th Gen. User Manual.

Why do I see code on startup and shut down?

Hello everybody,
I have a new iMac and for some reason when I boot up, or shut down, I can see a screen full of code. It looks like it is all the bootup information that the iMac is going through. I haven't seen this on other macs. Does anybody know how to turn this off? It was doing this right out of the box for some reason. I have applied all updates and it is still doing it.

Hi and Welcome to Apple Discussions!
Normally the things you are seeing are only shown when you use verbose mode. To do this you need to hold down command+v when booting. I have never heard of nor seen a Mac which does this without holding down these 2 keys. As stupid as it may sound: I'd try this key combo and maybe it'll "go away" next time you boot again. Since I don't know of a setting which would force your Mac to verbose mode I don't think there is one. Maybe your keyboard is defective resulting in command and v keys being "sent" to your Mac? So you could also try to disconnect your keyboard at boot...
Good luck!

MacBook fan broken (computer overheats and shuts down)

I'm pretty sure my MacBook has a broken fan. I can't hear it, even when the temp is measuring upwards of 180 degrees, and Fan Control is set to run it at a minimum of 3500 RPM and reads several thousand RPM, even though the fan is off. I think it broke yesterday, but previously there had been strange clicking noises. I can run it for a while when I'm not doing anything intensive (~135°–145°), but when I run BOINC or try to play games, the CPU heats up to over 180° and it powers off in a few minutes. Does anyone else have this problem? Is the fan stuck, or did a wire come loose, or is the fan motor broken?

They should be able to fix the fan with out doing anything to the drive. They might be able to do it while you wait. I would call and talk to them about it. I personally keep a back up of my system every week and always before a repair. I also have never lost data on a repair yet. I had a fan replaced on a Powerbook and had no problems with my data.
Thanks for the .

My macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated

my macbook pro 2006 fan goes high and then makes a fast beep and shuts down it been happening since i updated it should i update to lion?

No, this problem should be solved.
The MBP shuts down when too hot, to protect itself. First see if it is a process running astray: start Activity Monitor (in Applications/Utilities) choose <all processes> and click the %CPU column: are there processes that are using more than 50% cpu power? If yes click it and quit it, and tell us which one.

OS X installers have always been fairly specific, hardware-wise. I haven't read anything reflecting that situation with the Recovery HD, so it may be that the Recovery HD created for the MacBook Pro does not have the necessary drivers for the Mac Pro. Obviously, nothing definitive here, but a possibility.

I have an MAC OSX 10.6.7 and when I turn it on the fan keeps running. I shut down/turn on and it's the same. Any suggestions? Thanks.

jean156,
I am a little confused, you are posting in an iMac forum however your profile only indicates you have a MacPro. While I agree a SMC reset may help please carefully read the link The hatter provided because different Mac's have a different processes for resetting the SMC.
In the mean time you may want to update your profile (Your Stuff in upper right and click Profile) and also please post in the correct forum to avoid confusion.

Mac Mini LED blinks and shuts down at startup, takes 2-3 tries to boot...

I have a Mac Mini PPC 1.42GHz. When i boot it up after non-use (cold), the LED blinks once per second and it boots all the way into MacOS and shuts down several seconds later. It will usually do the same thing the second time around. On third boot its usually fine. Not thinking its related, I have reinstalled MacOS anyways. No good...
Thanks,
Rich

Welcome to Apple Discussions!
The flashing LED is usually indicative of a power-on self test failure, normally leading to the system failing to boot at all. Once per second would indicate the system fails to recognize available RAM.
The fact this happens when the system is cold (with an implication that it doesn't happen when the system is warm) might indicate the RAM module is no longer firmly inserted, or that the contact face on the pins has oxidized slightly. In this situation, I'd begin by opening the system and removing and then reseating the RAM - in the G4 minis this is relatively easy since there is only one RAM slot, and it is exposed with just the top of the casing removed.

MacPRO boots and shuts down in 1 motion

Evevning forum,
After returning home I have tried to bootup my MacPRO (early 2008) and the machine is acting weird. Before I left all was working fine. It seems as soon as I press the start button the computer tries to power up and shuts down straight away, within in seconds. Could this be a power supply issue as many seem to have fallen fate to this issue. If so wha are the cost of a new one?
Thanx in advance

Was it plugged into a UPS?
Was it unplugged from power?
Have you tried an SMC Reset?

Symptoms
If your Macintosh computer won't turn on, here's how to troubleshoot it. Please keep in mind that although your computer may display similar symptoms that prevent it from showing video, this article discusses what to do if the computer won't turn on, meaning that when you press the power button:
You don't hear a startup chime.
You don't hear any fan or drive noise.
The power button or power indicator doesn't light up at all.
If your computer doesn't display any video, it may display one or more of these similar symptoms when you press the power button:
You may hear a startup chime.
You may hear fan or drive noise.
You may see the power button or power indicator light up.
If any of these conditions occurs, see Troubleshooting: My computer has no video instead.
Resolution
If your computer won't turn on, try each of these steps:
Make sure that the power cord is plugged into a working wall outlet, and that it's properly connected to the power adapter. (To check if the wall socket is working, plug in a lamp or other electrical device.)
Make sure that the power adapter is properly connected to the power port on the side or back of the computer.
Disconnect all accessories that are plugged into the computer, such as a printer, hub, or other mobile device.

ZV6000 Overheats and shuts down

My ZV6100 has started to overheat and shutdown. I have noticed the cooling fans are not coming on as the computer gets hot. However after overheating and shutting down if I wait a few minutes and restart the computer both fans come on and stay on. So it's like this, when I start the computer and its cold the cooling fans come on for a short time (at startup) and then go off. As the computer warms up and then gets hot the fans do not come on as they should to cool it back down. Any ideas?
This question was solved.

Try a hard reset of the bios, power down, unplug the power cord, remove the battery, hold the power button down for 30 seconds, insert battery and connect power cord, power up, see if anything changes.

IMac fan runs full speed on shut down

Hi Everyone, this has probably been discussed before, but I may have some new information to add that could interest the tech savvy people out there.
My iMac runs perfectly fine; more or less as it did when it was new. In OS X, when I shut down the computer, the fan runs at full speed indefinitely, unless I unplug it or boot back up. When running, the fan is perfectly normal (increases speed a bit when doing something taxing). I've never heard it at full speed before until this started happening. After following the SMC reset procedure with no luck (I'd like to add that the SMC reset only says it relates to fan problems when the computer is ON), I searched a bit and noticed there are one or two cases where a problem like mine was believed to be a motherboard issue, and therefore a costly fix.
However, here's the fun part. When booted into Windows 8.1, shutting down the iMac does not cause this issue to occur. It stays silent, as it should, even if I disconnect then reconnect the power. This leads me to believe it's unlikely to be a motherboard issue. However I've wiped, restored, and reinstalled fresh copies of Mountain Lion, Mavericks, and Windows 8.1, and the result is still the same: if I don't want to have to unplug it from the wall, then I have to use Windows to shut it down.
So then, my questions are these:
-What is the difference between shutting down from OS X and shutting down from Windows?
-Is an operating system allowed/able to touch BIOS settings?
-Is it possible to still be a hardware problem, given this difference?
My default OS is OS X, and it makes no difference if I change that to Windows. I also did a PRAM reset, even though that has nothing to do with fans...
I'd certainly like to avoid a costly repair, if it's just something that a future software update will fix.
Thanks in advance!

Hey, thanks for the response.
The "Startup after power failure" option was not checked.
I'll try the Extended Hardware test when I get some spare time again - probably tomorrow night. After that I suppose it is time to either take it in for service/diagnosis, or just keep using Windows to shut it down. Sleep mode is unfortunately not an option because it eventually goes into hibernate state, which has the same problem as turning off. I don't like to leave the computer on all night, just from a power-conscious point of view (but yes, I know today's iMacs use very little power). I have it on a power bar now, so I just flick the switch off when I power down. It's not bad as a temporary solution - perhaps permanent if the shop says they have to replace the motherboard.
As for contacting Apple... I had a 1-hour conversation with them about my iCloud account, because it suddenly stopped working on this Forum site (hence the new account with no points). Anytime I sign in, it forwards me to the "page not found" error page. This happens even if I sign in on the apple store then click over to here. If my login info has an open session, then Discussions just doesn't work. They were completely baffled (understandably), because the account works on iTunes, iCloud.com, Apple store, and everywhere except Discussions. I was on the phone with them for over an hour - and the kicker is, even after telling them the same thing happens in other browsers, from other computers, they actually forwarded me to the iMac team. This is when I lost faith in Apple support. When one of the staff asked why I don't just phone about the issue, instead of trying to get access to the forums just to post about it, I told them I didn't want to pay $50/hr (or whatever the insane rate is for Mac hardware issues), only to be put on hold and sent around between departments, just to be told I need to send it in for service, which I'm probably not going to do if it's the motherboard. They never did get back to me about my account issue...
Anyway, sorry for the rant, I'll keep you posted about the hardware test and more SMC resets.

Is Lion slow booting up and shutting down?

After I installed Lion, my macbook pro is slow to boot up and shut down. How can you turn off "re-open windows when logging back on"?

The beeps on startup are often indicative of RAM problems. The opening chime is the only normal noise on startup. Shutdown should be essentially silent. To the Apple store, PRONTO!
Ciao.

Recent freezing and shutting down every down 10-15 minutes and hard to log in to internet very slow

My son has 2009 Macbook white version and recently (last week or so) freezing all the time, cannot log on to internet, and shuts down every 10-15 minutes. Is there a download (free hopefully to clean it up for any spyware or maleware). He is a student and very busy in University and cannot be without the computer?

He will need something to back up onto like an external hard drive. The disks are necessary if the hard drive needs to be repaired, you can't repair the boot volume so you need to start up from an install disc and run Disk Utility from there. When you talk to him have him resettle SMC and pram, sometimes unexpected shutdowns can be corrected that way. The freezing is another issue, I'm concerned with the health of his hard drive. Another thing to ask when you talk to him is how much total space and how much free space does his hard drive have?
