IMac switches on all on it's own!

Hi Ladies & Gents.
Bit of a funny one! My 2GHz Intel Core Duo 20" iMac switches on all on its own. Been an OS X user for over 5 years, but am a bit boggled by this one.
Have gone down the System Preferences route:
Energy Saver: Wake for Ethernet access, unchecked. Restart Automattically, unchecked. Schedule, both unchecked
.Mac: Manual Sync only
iCal: only Alarms set are email only. Also, have deleted iCalAlarmScheduler from Login items.
Have a very "tidy" hard drive, 2 Lacie Hard Drives only switched on when required and hardly any 3rd party stuff installed (Onyx, Firefox, Excel, Speed Download & a few Widgets). Network wise, wireless to a Netgear ADSL .n router which I've had for over 6 months, with no previous problems.
My main concern at the moment is that it powers-on the 20" ACD aswell. Which is always turned off manually at the monitor. And also, I cover my kit when i'm away with Tucano covers - 'affraid I'm gonna come back from a week or two away from home and my Mac will have overheated!!! Could unplug from the mains, I know!
I believe the SMU problems of old don't apply to Intel Macs. Am I right?
Bit of a weird one for someone to have a think about!! The Genious Bar were a bit perplexed!!!
Thanks in advance Guys & Gals!

Do you have EyeTV at all? If so check what TV programmes you've got set to record.
Alternatively try an SMC reset (link) as this controls all aspects of the computer's power.

From time to time my imac is switching off all of the sudden, who knows what it could be?

Once every few days my imac (2010) is switching off all of the sudden. It is happening since a few weeks. Who knows what it could be?

Hello Tommy,
Have you blown the dust out lately?
Get Temperature Monitor to see if it's heat related...

Imac switches itself off.

imac switches itself off. Will not restart unless power supply is switched off then on again.

Hello
you could try an SMC reset
1- unplug all cable
2- push power button for at least 5 sec
3 - plug power cord - keyboard - mousse and restart

IMac fan running all of the time

iMac fan running all of the time - how to stop. seems that after several hours iMac then shuts down on it's own accord.
Is there any help online - or take the 15 month old iMac to the shop ?

You can try an SMC reset, which can sometimes fix a goofy fan:
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.
What you're describing, however, sounds like a temperature sensor that's either acting correctly or it's not. I'd install iStat Pro from http://islayer.com/apps/istatpro/ , and monitor the temps and fan speeds.
I'd also run the Apple hardware test to see if it finds any obvious hardware issues. This Apple note tells how to run it: http://support.apple.com/kb/HT1509 (if you have Snow leopard, look down towards the bottom of the note for directions).
When the fan starts roaring, have you looked at your Activity Monitor (on your hard drive in applications/utilities) to see if there are any programs that are driving up CPU usage to high levels? That could contribute to an overheating situation.

I connected my external hard drive to my new imac to put all of the information from my macbook onto it. i have been working on the macbook now and want to reconnect the external hard drive so my imac is updated with the work. How is that done?

As I said, I don't use Time Machine, so it'd be best to wait for an "expert" answer, but, with my very limited knowledge, I'd say: probably not - so, for now, I'd suggest you read up on Time Machine:

And, you might be attracting more knowledgeable answers if you were to post this question in the Time Machine Forum (part of the Snow Leopard forums).

Thanks Chris The phone has been great until this morning. When using the camera it seemed to shut down, then it was just looping the restart, and finally into recovery It never rains but pours Thanks anyway
BTW, the phone has never been jailbroken or anything. Stock standard

Hi Spenny,
Do you have any Apps that are not working properly or Apps that appear open from the Dock and shows the menu bar but no App window?
Have you looked here (System Profiler): Go to Apple Menu > About this Mac > More Info > Contents > Hardware > Diagnostics... you can see what kind of Power up info is contained...
If it were me, I would go ahead and try resetting the SMC and pay careful attention to the instructions. If this does not help, I believe your machine is not actually turning off. So, if were me, I would force a shut down by holding the POWER BUTTON till machine turns off, this may take a few seconds but it will shut down and then go through resetting the SMC again....
Let us know, good luck, Rick

Since you are using OS X 10.6.8 I would recommend that you reboot from your Original Installation Disk that came with your computer while holding down the D key. Then run the AHT (Apple Hardware Test) or Extended Apple Hardware Test to see if any of your hardware components are failing. Then from that same Disk I would run Disk Utility to use "Disk Repair" and then "Repair Permissions" and see if that solves the problem.
Hope this helps

Welcome to Apple Discussions!
Did you format your hard disk on that Mac any differently?

Shouldn't the ring/silent switch silence all sounds?

Shouldn't the ring/silent switch silence all sounds at a system level, including those made by third-party apps? That's how my Treo worked, and it worked well.
(I'm aware that clock alarms still ring, regardless of the setting, as pointed out in the user manual: that's a nice feature in case someone forgets and leaves the switch set to "silent.")
But for example, I was in a long meeting the other day, and the topic veered to something in which I wasn't involved. I whipped out my new iPhone, set to silent, and decided to give Scrabble a whirl. You can guess what happened: its lame startup sounds made every head turn. I gave a sheepish look.
Should my beef be with Scrabble's developers, or with the iPhone 3G itself? Annoyingly, there's no way to silence Scrabble's startup sounds, even if you turn off all other in-game sounds, so that's just plain annoying. But it still seems to me that I should be able to keep the in-game sounds (which I like) on, but silence them with the hardware switch when needed.
UPDATE: Found this thread, which addresses my question. Reading through it, I think it's Apple's responsibility to invoke a system-wide mute (with the exception of clock alarms) when the switch is set to silent.

I too assumed the phone mute button would silence the speaker in all places. I thought that's what it's for. But I wrote to EA for the Scrabble issue. I got a dumb generic response. Now today I got a servey asking me to rate their serivce response. Oy!

After updating my 4s to ios6, I'm having the same problems with wi-fi switching to cellular on it's own and running up my data usage.....anyone else having this problem?

After updating my 4s to ios6, I'm having the same problems with wi-fi switching to cellular on it's own and running up my data usage.....anyone else having this problem?

The iPhone is DESIGNED to switch to cellular data when asleep, unless it's connected to a power source, in which case it will stay logged onto the WiFi network. iPhones have ALWAYS behaved this way.
Either turn cellular data off at night, or leave your phone connected to a power source to continue the WiFI.

Has anybody seen If this can be done programmatically any help would be gratefully welcomed thanks.

i am not sure about the script, why not create crawl rule which will exclude the allitems.aspx from showing in the search results.
Go to search service application, crawling section, click crawl rules to create a crawl rule to excludehttp://*allitems.aspx page.

Is there any way too see all data on all enteties an user owns.

Hi all,
Is there any way to see all data an user owns in CRM2011?
Maybe an custom report or view?

I could only think of one solution to this, a little bit of code to get a list of records a user owns. The List contains Entity objects with the Id & LogicalName. You could do this with a report too but you'll have to query every entity...
public List<Entity> GetOwningRecords(IOrganizationService service, Guid systemUserId)
List<Entity> owningRecords = new List<Entity>();
RetrieveAllEntitiesRequest retrieveAllEntitiesRequest = new RetrieveAllEntitiesRequest();
retrieveAllEntitiesRequest.EntityFilters = EntityFilters.Entity;
retrieveAllEntitiesRequest.RetrieveAsIfPublished = true;
RetrieveAllEntitiesResponse retrieveAllEntitiesResponse = (RetrieveAllEntitiesResponse)service.Execute(retrieveAllEntitiesRequest);
foreach (EntityMetadata entityMetadata in retrieveAllEntitiesResponse.EntityMetadata)
if (entityMetadata.OwnershipType != OwnershipTypes.UserOwned)
continue;
try
QueryExpression query = new QueryExpression(entityMetadata.LogicalName)
ColumnSet = new ColumnSet("ownerid"),
Criteria =
Conditions =
new ConditionExpression("ownerid",ConditionOperator.Equal, systemUserId)
EntityCollection result = service.RetrieveMultiple(query);
foreach (Entity entity in result.Entities)
owningRecords.Add(entity);
catch (FaultException<OrganizationServiceFault>)
Console.WriteLine(String.Format("Couldn't retrieve the records for {0}", entityMetadata.LogicalName));
catch (Exception)
Console.WriteLine(String.Format("Unexpected error for {0}", entityMetadata.LogicalName));
return owningRecords;
Hope this helps

How do I keep my page from zooming in and out and my cursor moves all on it's own

I have a mac pro and my page keeps zooming in and out all on it's own and my cursor just moves around with out me doing it, How do I keep my computer as it's suppose to be normal

Mac Pro or MacBook Pro,What OSX, if you have a track pad (MBP) check system preferences track pad zoom&scroll, or zoom options functions (slightly different depending which OSX) if a mouse holding control while using wheel will affect the screen, as well as swiping on a track pad.
