Auto Sleep Doesn't Turn Fan Off

If I put my Mini to sleep the fan turns off no problem, but if the Mini puts itself to sleep the fan stays on.
(I think it's the fan not the hard drive, but am not 100 percent sure.)
Any ideas would be welcome. Thanks.
Mac Mini 1.66 GHz Intel Core Duo Mac OS X (10.4.8)

Thank you. That is definitely helpful as I have now confirmed that the mini is not asleep — no pulsing of the white power light when left to go to sleep on its own. The light pulses fine when I select Sleep from the Apple menu. It just appears that the screen goes dark and then nothing further happens when I just leave the mini.
I have tried various things like resetting the screensaver and sleep times and have also tried throwing out the PowerManagement plist file but that doesn't seem to have helped (although I didn't log out and then back in). Would that help? I get nervous messing around with files in the System folder!
Anybody got any further suggestions, please.

Rest the SMC, do it 2-3 times. Please click Intel iMac SMC and PRAM resets for instructions.

"sleep 1; xset dpms force off" doesn't turn backlight off

I have a 13'' Macbook Pro connected to a 24'' Apple Cinema Display LED monitor and I'm running a XFCE as DE, and running the nvidia-beta + nvidia-utils-beta from AUR. I'm using the external monitor as the main screen and the MBP display turned off. I don't have a separate screensaver installed.
Until a couple of months ago issuing 'sleep 1; xset dpms force off' would turn the backlight of the Apple Cinema Display off, which is how I like it. Now however the backlight switches off for a second, switches on again showing a blank (black with backlight on) screen. I experimented with the xset screensaver settings (xset s ...) but none enable me to turn the backlight off.
output of 'xset q' :

With the Apple Cinema Display disconnected and using only the laptop monitor 'sleep 1; xset dpms force off' does turn the backlight off. So it seems to be something about using the external monitor.

Thank you! Nice to know I am not alone. Googling has brought me nothing, though it's difficult to pinpoint discussions about something like this, as users may not know enough to work out what the problem is and not even mention DPMS!
Anyway, my setup consists of an i7 running on an X58A board with an ATi 5850 card using the radeon driver, from testing, not git. System is fully up to date with testing enabled, X has little manual configuration besides telling it what driver to use.
I should mention that prior to this, I was using the fglrx driver, and had a similar but different problem. With the fglrx driver, when using DPMS, after an undetermined time, could be minutes, could be hours, X would peg the CPU and become unresponsive, not even able to change to another VT. Another issue difficult to google as a lot of users wouldn't know to ssh in to have a poke round. I switched to radeon in an effort to get rid of this problem, only to have it replaced with another!
Neither times did anything out of the ordinary turn up in any logs. Frustrated isn't the word! For now I have turned off monitor power saving in KDE though this isn't ideal
EDIT: Turning off monitor power saving in KDE didn't work, so I have no added
Section "ServerFlags"
Option "BlankTime" "0"
Option "StandbyTime" "0"
Option "SuspendTime" "0"
Option "OffTime" "0"
EndSection
to /etc/X11/xorg.conf.d/10-xorg.conf
Of course, I'd like to be able to use DPMS! Anyone have any ideas how this can be rectified?

IPhone screen doesn't turn itself off when on lockscreen

Ever since I updated to 3.1.3, if I leave my phone somewhere locked, and I get a notification it lights up the screen, as it used to, but then it never turns itself off again. Which means if I'm at work for example, get a text 5 minutes after I start then my phones screen is left on all day, leading to the battery being flat by the time I finish work.
I have auto-lock set to 1 minute so that is no the issue.
If anyone has any idea on what could be causing this and how to fix it I'd appreciate it!
Thanks

Then the next step would be a restore, with or without your backup. See p. 204... http://manuals.info.apple.com/enUS/iPhone_UserGuide.pdf
You might also play around with your auto-lock settings... on/off, different times, etc.

IPod doesn't turn on/off sometimes

Sometimes, like after I sleep I go to turn on my iPod on the way out the door and it won't start - pressing any button, holding play/pause, etc. Only way to get it to start is to reboot it while it's off (hold menu/select), then it reboots and takes about 15 seconds, and it starts fine.
This only happens sometimes.
On the same token, sometimes it refuses to shut off. I have the backlight set to like 5 seconds so it keeps battery life. So sometimes it just won't shut off. I hold the pause button and nothing happens, just backlight shuts off after 5 seconds, and then when I release it the backlight comes back on. It doesn't shut off.
Anybody know what the **** is going on?
I stopped using iTunes b/c the **** thing always crashed on my PC and use a plugin that makes it workable with winamp fine - but don't say that's the reason - it was doing it when I was using only iTunes.
Using the latest version of iTunes as well as the latest iPod software.
Anybody have any suggestions?
I rebooting it, obviously, please don't tell me to do that. It'll reset if I plug it in - but it still takes 15 seconds or so if it's jammed up and not starting.

As far as the issue with turning the iPod on, I don't know what would cause that. But the issue turning off-that happens to me all the time!
As a caveat I don't have any official info on what causes this problem. For all I know its a software glitch or a processing delay. However, in my experience I think it has something to do with the touch wheel registering movement at the same time as you are holding down the pause button. If you have big fingers, like I do, this is more of a problem. My kids have no problem turning my iPod off, but 7 times out of 10, it takes me several attempts. I've learned to try and be a bit more precise in my button mashing . I have gotten better at turning off the iPod just by trying to pinpoint the pause button and not move while I'm doing it.
Hope this helps!

Task Auto-Assignment in PJM (turning it off)

My client is looking to turn off Task Auto-Assignment in Project Manufacturing after a restructure of the Project WBS / FBS. It will no longer be needed.
I was wondering if anyone has done this. What are the steps? What are the concerns of doing this (data corruption, conversion, etc...)? Release 11.5.10.2
I do know that one step in order to disable task auto-assignment is to change Project Control in Project Organization Parameters from Project to Task. Anything I am missing? When I do this and then try to assign the Project and Task to the Job (work order) it will not save. It gives me an error (Error: Task Auto Assignment Rules do not exist for the Project Assigned to this job). The work around is to turn task auto-assignment back on (Project Control field), assign some rule to the project in Project Parameters, and then turn the task auto-asignment back off. This then allows me to "save" the project and task to the Job (work order), but I would never be able to roll this out in a Production environment.
Please help. Thanks in advance!
Andy

Hi
I haven't tested it, but may suggest some considerations.
All inventory and WIP transactions need to be costed and interfaced to Projects by cost collector before you change the setup of the project control in the organization.
If you use Order Management, you might need to insert task number to any open sale order line.
If you have open requisitions and purchase orders, they also need to get task number on the distribution lines. That is true even if the items were already received but not yet billed.
On hand items in Inventory project locators, need to be transferred into project and tasks locators.
Any planned work order, even if not yet released, need to get the task number.
Based on the quantity of existing locators, jobs, POs and sale order, you might want to consider if it would not be easier to setup a new inventory organization with project and task control, and then move all PJM activity from existing organization into the new one.

HP Folio-2000 Turn fan off/down

Hi there,
Is therew any way I can reduce the noise coming from my Folio laptop? I purchased it thinking it would be much quieter than my 4yr old notebook, but the opposite is the case.
The fan is permanently on, even when no programs are running, and the fan is pushing cool air out the back!
I have updated the BIOS, and tried using several fan management software programs....surely there must be a way to make this thing a little quieter????
Any help is greatly appreciated, thanks!

No you can't. Reason it probably shuts down is because cpu temps peak over safety threshhold at times thus it shuts down to prevent damage.
Cooling systems on hp's are not the best when working so thermal stress on cpu,gpu & mainboard will be bad & failure failure will occur quite quickly.
Fan assembly is very cheap & can be done DIY if you have some skill in dismantling these sort of things & following hp service manual & other online guides.
I expect a new fan & new thermal paste & shimming along with cleaning would do wonders for running temps & long term health of the notebook.

Setting access='readOnly' doesn't turn validation off ?

Hello
I have a TextField and set its type to "User Entered - Required" at design time and later, I programmatically set the access to readOnly. The TextField becomes read only but the validation is still active when I submit the form.
Is this behavior by design?
I have to change its validation property inactive explicitly? Something like TextField.validate.nullTest = 'disabled' ?
Any idea?
Thanks

Yes, you should do:
TextField.mandatory = "disabled";
TextField.access = "readOnly";

Mac Pro does not auto-sleep (manual sleeping if fine!)

I have a small annoyance with my 2009 (Nehalem) Mac Pro I am wondering if someone can help with, or suggest something, please:
The Mac Pro does not auto-sleep; ever. I have played around with the sleep time settings, and enabled or disabled the 'sleep drives' option, but to no avail. Mac Pro will stay on, no matter if I am logged on OR even on the 'log on users' screen.
That said, I can sleep the Mac Pro manually at any time, and without any problems; it stays asleep without a hitch, and wake-up is flawless.
There is nothing in the console log that would tell me why the auto sleep doesn't function. I deleted the sleep plist and re-set, but again, no change.
Any ideas? Not sure what could signal the system to not do auto-sleep?
It's running 10.6.3.
Cheers,
Dan

Exactly the same problems as those described above: forced sleep works (by using the power button or closing the lid) but automatic sleep doesn't (using 'Energy Saving' preferences).
Tried every single piece of advice here and on other posts: reset PRAM/ SMC, verified disc, repaired permissions, deleted the power saving preference files, cleared caches & history, restarted in every conceivable mode... The only things that worked were safe boot and creating a new user account which means it must be a software issue.
Disabled/ removed/ paused/ reinstalled every piece of software I could but to no avail. The most frustrating thing? Having to wait for 5 mins every time I tried something to check whether the damned thing was going to go to sleep.
In the end, and in desperation, I took the advice of Dino X and downloaded PleaseSleep. Success! A genius piece of software. It forces sleep when the Energy Saver preferences cut in but, even if I don't set exceptions, it won't force sleep if there's a DVD playing (for example).
Only had the Mac for a few months and I'll never go back to that other, unmentionable operating system; the Mac's just too good but I'm vexed that I'm having to use third party software to get it to work as it should (and was) - feels like a bit of a Win*s solution to me.

My Itouch is stuck on a screen with a USB cable pointing to an iTunes symbol but when i try and connect to itunes it doesn't recognize it. I can't turn it off because my touch screen isn't working although my sleep button is, Help please?

My iPod got slightly wet but only slightly. Could this have done it?

Turn it off. If it got wet somehow, you may try drying your ipod off. The slow method would be a sunny window sill. You could use a hair dryer on LOW, pointing it at the contacts. When it drys out, charge itand try a hard-reset. If it still doesn't function properly.... ?

My iPhone 4S keeps turning itself off when I still have battery life and then it doesn't charge?

It's only just started doing this and it's really annoying me now!! Ha
I'll charge my phone up overnight then a couple of hours into the next day the battery wil be down to about 20% then it will say I only have 10% left even though I will have 20% if you see what I mean? And then to top it off it turns itself off and won't let me recharge!!
It did happen to my iPad the other week but that seems to be fine now.
I've tried changing and checking chargers etc but they seem to work it other people's and my iPad seems fine now

Hi there glee154!

Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for coming to the Apple Support Communities!

Hold down on the sleep button and the home button at the same time for about 10 seconds until the Apple logo appears on the screen. Ignore the red slider. When the logo appears let go of the buttons.

My iphone turned off by itself and it doesn't turn on

My iphone turned off by itself and it doesn't turn on, What should i do????

IIf the battery was completely drained it might take some time before the phone will respond. Wait at least 30 minutes with the phone connected to the charger. Then reset your device. Press and hold the Home and Sleep buttons simultaneously until the Apple logo appears. Let go of the buttons and let the device restart. If the phone starts up let it continue to charge until it's 100%.
if the broken button will not let you do the reset Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.
