Reset the SMC:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

HT1379 my fan wont turn off in y imac computer

Last night the fan on my mac came on and it never went off it has been around 16 hours and it is still on what should I do?

Search these discussions for fan full speed and sort by date.

Fan wont turn off???

I installed Fan Control of my mac book pro right now and I didn't like it so I deleted it. I deleted it by right clicking on it in the system preferences window and clicking on remove. And then I did a SMC reset. But when I turned the computer back on, the fan is still running at full speed. How can I fix this?

Before removing Fan Control you should reset the fan speeds to their normal idle, then remove the program. Download Easy Find - VersionTracker or MacUpdate - and use it to search for the remainder of what Fan Control installs besides the preference pane.

Fan wont turn off... mb slooow!

I bought my macbook about 6 months ago and it was super fast... up until about 2 months ago.. not sure what happened. Also around that time the fan started coming on for no reason at full speed. I called support and they had me empty my caches... i immediately noticed a difference.. at least with the fan. the mb is still noticeably slower that when i bought it.
my moms bf updated my memory from 2 - 4gb but i havent really noticed much of a difference.. still slow. and now my fan started coming on for no reason again i emptied my caches again and nothing.
I don't really do any downloading, i just use my computer for email, school, internet etc.. like everyother college kidd.
any ideas?? im annoyed!!!

Going from 2 GB to 4 GB of RAM is not likely going to make any difference in speed unless you were running very RAM intensive applications which you are not according to what you said.
But to say the fan is running for no reason is probably not correct. The CPU is probably hot. The question is why.
Run Activity Monitor and select "All Processes" in the upper center of its window. Now select the %CPU tab just below that. This should show the amount of CPU usage of all the processes that the computer is using. Most of them should read 0. a very few should read a small number. If anything is reading over 10% continuously this can explain your fan being on. Report back here if and what items are using a lot of CPU and maybe we can get this straigthened out.

Does anyone know why the fan on my imac wont turn off?

Try resetting the SMC, it may take 2-3 attempts. Please post back with the results. If you're not sure how please follow the instructions in Intel iMac SMC and PRAM resets

Reinstall OS X:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

HT4623 What do I do if the itouch was turned off while it was updating? I cannot get it to turn back on or talk to the computer.

What do I do if my ipod touch was turned off while it was updating to the new IOS? I cannot get it to turn back on or talk to the computer. It either shows the start apple screen or a blank white screen.

to all who have taken the time and effort to read my post....thank you. I was certain last night that I would be taking my Macbook into the Apple Store 7 hours drive from my location. I last used it with an Ethernet connection last night. I am up eary and I just turned it on and the WiFi is working again. ?? ???? ?? I have no idea.
Thanks to the firt person who replied especially and gave some suggestions. I am going to take it in to an Apple store in Toronto soon and leave it with them fo a couple of days. (I even deleted my VPN and it is a paid suscription).

How to safely turn off the computer while the motion servo is still enabled?

When we use PCI-7344 and set it for serve closed control, I have found a very serious problem
in using the control card in this mode.
As the card is able to control motors only with the computer at power on status, but if we are very
carelessly to shut down the computer and without the notice to turn off motor driver power first
we would always get serious sudden moves of the motors, and might cause damages to the system. The same situation also applies to when control the motors under open/closed loop stepper mode.
How should I do to prevent the above situation?
(note: in my system, we have hook up relays and timers if we could set DIO bits before shut down
the computer. But
still, there are a certain occassions that the operator would still forget to set the DIO bits
and turn off the computer directly)

The Inhibit output pin of the motion controller (also called drive enable) is the best way to achieve this. It is basically a signal that most power drives take in as an active low input so that when the powergoes out of the computer, the line goes low and immediately kills the axis so that no servo ouptut command affects the motor.

I tried to eject a cd, didn't work so I turned off the computer and now it keeps getting stuck at the gray screen. How do I fix it?

Here are a few more details. I put in a game cd for a windows computer, once I opened the folder on the desktop I noticed the install application was .exe so I tried to eject the cd but no matter what I tried on the computer it wouldn't come out. I will say though that I didn't try the manual cd eject cause I didn't have anything small to hit the button in the cd drive with. It was getting late so we decided to just turn off the computer and leave it for the next day. I can't remember if we turned the computer off with apple shut down or by holding down the power button but we walked away pretty quickly before it was fully shut down. The next day the computer won't turn on. When I walked into the room I was the computer stuck with a grey background with the apple logo showing and the circular thing under it frozen. Since no one was in the room I held down the power button and turned the computer off. We tried to start the computer again later but again it keeps getting stuck at the same spot. Now when we hold the power button down to turn it off I'm not sure if it's really turning off all the way. The screen goes dark but it sounds like the fan is still going. I tried disconnecting everything but the keyboard and mouse but when I started it up again it got stuck on the grey screen with just the apple logo. I'd really apprechiate help on this cause I live in Germany right now and support call centers work so much worse when you don't speak the language well... Thanks for any help you can give!

Restart your computer while holding down left mouse key. That will eject the CD and your Mac will start as normal.

It just wont turn off!

Basically my Ipod is less then a year old. Its run fine up until now. Its had the usual bugs freezing every once in a while but on the whole its worked.
However, since the other day it will not turn off! I pushed down the play button on the click wheel held it and nothing! I checked that the hold button wasnt on then did it again, still nothing so I reset it...still it wont turn off. I clicked the sleep button, no responce. I let the battery run dry then charged it again nothing so I repeated the process then plugged it into the computer and still it will not turn off!
I'm at my witts end. I don't want to restore the thing but I fear I may have to. Can anyone help me?

Rob. I had this happen and it drove me nuts. Try this. Turn the "hold" button on top of your IPOD to "hold". Then turn the hold button back on. HOLD DOWN the "menu" button and the "ON" button, (that's the center of the wheel) at the same time and in a few seconds the Apple logo should come on the screen. That resets the entire IPOD but it won't lose your songs or anything.
I hope that helps.

My i pod wont turn off ?

yeah so i let it charge for like a day, which ive done before, but for some reason now it wont turn off so i cant take it any where cause i dont want the battery to die
its like ill sit there for pretty much a whole song holding the pause button but it still wont turn off, but the pause button works cause i can pause a song
ive tried:
-charging it some more
-leaving it alone for a wile (all day, like not playing anything)
-hooking it up to my computer (its been a while cause i only do it when i download stuff)
-putting it on hold (my friend does that to turn it off)
so yeah is there any other way to turn it off? or has this happened to anyone?

I just press menu+select(or enter or whatever its called) for about 5 seconds. that should restart the ipod( i think it clears the cache but correct me if im wrong). Anyways, do that and you shouldnt have any more problems (at least for a while)
Just do that everytime it doesnt want to shut off, thats what i do

My ipod wont turn off!! please help

i did nothing to my ipod to make it not turn off. i was listing to it for a while and when i decided i was done using it i wanted to turn it off and it wouldnt work. i can go from one song to the next with no problem and i can pause it and all that good stuff but it just wont turn off. i tried letting it cut off by itself( put ot on pause and wait for a couple of min) but its been almost a half an hour and it still hasnt turn off. please help me!!!

Have had the same problem for a couple of weeks. Have tried the 5 Rs and other tips found on this site. Nothing seems to work. Only thing that does work is if ipod is connected via USB and itunes is running. It can then be turned off and will remain turned off when you disconnect your ipod. But this isnt much help if you have to connect to your computer each time you want to turn your ipod off! Still waiting for a complete answer I'm afraid ......

Try the remaining items of:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

There's a black and white striped glitch on the left side of my screen on my Macbook Air! Its happened before and has been an easy fix, usually just restart or turn off my computer but don't know what else to do. Is there anything I can try now?
