Definitive fix for revving fans/freeze?

Is there a definitive fix for the revving fan & freeze issues in the early edition G5s (dual 2Ghz)? Also, does the above mention problem have any relation to the defective video cards in the same machines? -- no video signal on cold starts. card needs to be warmed w/ a hairdryer before startup!

Hi
Dont know if this will help you but I had a problem of high revving noisy fans, then it wouldn't power up. I sent it away and the said it was due to a little white strip fixed on the bottom end of the cover, which apparently effects the air flow. It was starting to curl up, it was straightened out and the fans are now very very quiet and I have had no bother since, including powering up

Fix for Blasting Fans with 10.4.4 yet??

Hello everybody,
It's been a while since I've checked back at these forums, but I couldn't find a solution going over some posts today. My fans have been CRAZY since 10.4.3, and 10.4.4 didn't help one bit. They're fine when in Reduced settings, which is really lame, because i bought the G5 for its power. Highest has no crazy fans, but has the annoying chirps. Automatic was completely fine until 10.4.3, and I want to be able to use it again. So has anybody found a solution to this yet? (From Apple or personal solution). Also the fans seem to go most crazy with Safari or Firefox use.
Thanks,
-Burak

Oh geez, here I am back on the boards again. Guess I never should have installed Tiger yesterday on the G5 and did the 10.4.5 combo to catch up. Had been PERFECTLY happy with 10.3.9 on it. No fan revs, very low CPU loads, sleeps when it should, yadda, yadda. Tiger sat on the shelf from first day of issue until yesterday. Finally decided a mid version update on 10.4 should have things resolved. Oh well, the fans rev'ing again are a BIG disappointment Apple!! There is absolutely nothing wrong with this G5 dually and it performed out-of-the-box perfect since Oct. '03 on each of the last versions of Panther and Jaguar.
So I'm here to verify, indeed Apple has a software problem with the Fans rev'ing on my G5. And ALL the fan rev'ing problems in the past...i.e. Jaguar and Panther both....were resolved in software revision updates at some point in time without changing a single thing on this Mac, not software, hardware or firmware.
C'mon Apple, I DON'T want to wait until 10.4.9 to get this irratic, unpredictable, annoying, unjustified fan rev'ing problem fixed.

Frustrated with lack of fix for LR launch freeze

This LR CC launch freeze issue is frustrating and the inability to get support is unsatisfactory.
The two Adobe solutions do not work.
Numerous uninstall/reinstall do not work.
Impossible to get support on the chat line.
Losing faith in the product.
Just join the long and growing queue I suppose.

Verizon can mail you a Sim for free. No travel time to a corporate store.

In their community help forum the not being able to activate is listed there as well as the fix.
Good Luck

Attention N200 Owners, I found a fix for the fan

In an attempt to improve battery life, I made an important discovery. Apparently lenovo is using the desktop CPU P States instead of the mobile ones. With my T7200 running at 2GHz, this means it's using 1.35V instead of the 1.225V it's supposed to be. This mistake on lenovo's part means increased heat output and a fan that has no idea how fast to run. Here's how to fix it:
1. Download and Install RightMark CPU Clock Utility. http://cpu.rightmark.org/download.shtml
2. Open the utility and select "Advanced CPU Settings" in the pane on the left side.
3. Towards the bottom under "Intel Core 2 Family Advanced Features", change the "CPU type selection" setting from desktop to mobile.
In order to make this change stick, you have to make the RightMark CPU Clock Utility run at startup.
1. Click on settings in the pane on the left side.
2. Check the box next to "Run at Startup"
3. Select "via Startup Folder" in the pull down box.
4. You may also want to check the "Start Minimized to Tray" box above, or the main window will open every time you start the computer.
Untill lenovo does something about this problem, this is all you can do. However, you will see an improvement in battery life and a reduction in noise, along with a fan that does not have ADD.

@iamdh
He doesn´t change the voltage of the CPU fan which could indeed be a little risky. He changes the voltage of the CPU which is according to CPU-Z by default (http://www.cpuid.com/cpuz.php) a little higher than the default voltage of the CPU.
I also noticed this before and did exactly the same with my 3000 N200. The difference is just that my N200 has a T5250 CPU but as it seems the same overvoltage problem. With his workaround the heat and powerconsumption is especially under high load reduced, resulting in a higher runtime.
On the other hand this has hardly any effect on the fan spining up an down when the CPU is idle.
Sorry, small addition:
I used another way to get the "right" voltages for my CPU. When I open RMClock my CPU already is marked as an mobile CPU, so this is not the problem in my case. But you can also change voltages for the different Pstates in RMClock manually. And this is what I did to get the default voltages for my CPU. Interested ones can find the necessary information here http://forum.notebookreview.com/showthread.php?p=2637648 (They describe how to undervolt a CPU but as a start it is just enough to supply the CPU with the default voltage instead of the "higher than above" voltage supplied by for example my 3000 N200)
Just for information: The default Voltage of my T5250 CPU is 0.95 Volt at idle and 1.25 at load. According to CPU-Z my CPU gets 1.063 Volt at idle and 1.363 Volt at load.

May have found a fix for iPhone 4 freezing/restarting/locking up issue.

Ok, so I am one of the many who have suffered from my iPhone 4 freezing, restarting and/or locking up on me.
I have combed through the discussion threads searching for a fix but never found one that was proven to work. Things like hard resets, restoring from backup, restoring from new etc... People would claim one of the above fixes worked only to return to the thread minutes, hours or days later to report that the problems had started again.
I understand that the fix that worked for me may not work for everyone, but I'm sure it will work for some. It is a simple fix that I have not seen mentioned in any thread and thought it would be worth sharing.
Fix: Settings > General > Reset > Reset All Settings
My iPhone 4 was either freezing, restarting or locking up on almost a daily basis, sometimes several times a day. Since resetting my settings almost a week ago, I have had no problems!
It is the simplest and least inconvenient fix I have seen, so it's worth giving it a shot!
Good luck, and I hope it works for most if not all of those experiencing these issues!

My iphone 4 just started to warm up and the battery is draining quick. Closed everything and reset to no avail. Turned off bluetooth, increased push time and checked location settings for new applications. Weather Doodle was a bit suspicious as it had a purple direction indicator next to the setting. The only other new app I installed was Lego instruct. I disabled one of the 4 mail accounts I had that is having network difficulties, went to airplane mode and still I see %1 drain every 10 or 15 minutes. I'll remove the new new apps and reset to see if it is related to the new apps. If that doesn't work, I'll try email account reset at home wifi and see if that fixes the issues.
Thank you for the information.

Any fix for MacPro Fan problem caused by the last firmware update?

Hi,
My macPro's fans have been going balistic on restart from sleep mode ever since I loaded that last firmware update that was supposed to address the MacPro fan control.
Any word on a fix... Is this overspeed damaging my hardware?

It is a bug in the firmware update because my MacPro never acted this way before the update was loaded...
Many have reported the problem... and some have not experienced it... Go figure.
Logic says this is not a bug. A bug with the firmware update would be universally felt, no exceptions. Firmware doesn't change its format out of the blue when it chooses to. What it does say is there are some Mac Pros that for whatever reason are not getting sufficient cooling in their position on the desk/floor, or the climate they are being used in. Since Apple does not publish the temperature limits internally for its machine, the best thing is to report this problem to AppleCare, even if the hardware test comes out negative.

Fix for rental movies freezing or locking up iTunes

Hi, I had this problem where rented movies would freeze or lock up my iTunes and I'd have to kill it with Task Manager. I rented 2 movies and had the problem with both. I had apple let me re-download the 2 movies after my rental period finished so that I could trouble shoot the problem more.
Apple care pointed me to this url: http://support.apple.com/kb/TS1421?viewlocale=en_US
So I created a new xp username and re-downloaded one of the movies in that iTunes. WOrks no problem!!
SO in the original xp username that's broken I completey removed these 2 folders: C:\Documents and Settings\username\Application Data\Apple Computer\iTunes and
C:\Documents and Settings\username\Local Settings\Application Data\Apple Computer\iTunes and now the original login works too!!
Hope this will be helpful to people out there.

I found this in an older post, although I didn't hear anything from support.
+I have heard from tech support from Apple. This is a defect in iTunes. There is nothing you (we) can do to fix it. We will have to wait for iTunes to release a fix. In the meantime, to get a refund, when you get your invoice from Apple for the rental, simply click on the "report a problem" link in the email and follow all instructions. Your money will be refunded. FYI this problem is occurring on Mac as well as Windows.+
*If this is true I really hope this issue is fixed before the release of iTunes 7.7!*

Here's a fix for Safari hanging and taking down the system..

There appears to be a serious bug in Mac OS X's lookupd which can pull the rug right out from under Mac OS X Tiger. While this bug could possibly be triggered in a number of different ways, there has been a recent rash of reports that have been tracked to some mainstream Web sites such as FoxNews.com using links to an adware site js.adsonar.com. This document describes a quick way out of the hang and a simple way to block links to js.adsonar.com from taking down Tiger again. While this doesn't fix the underlying lookupd bug itself, it prevents Mac OS X from hanging, while allowing you to continue using Web sites like FoxNews.com with full Java and JavaScript access enabled.
The symptoms of this problem are as follows:
You're surfing the web and the page you are on fails to completely load.
No further pages will load in your browser.
You can switch to other applications that may already be running and save any open files.
You can no longer launch any additional applications, their icons will bounce in the dock for a while and then they will just stop bouncing.
You can no longer use any other Finder functions.
You can no longer use command-option-escape to force quit.
You can not log out, restart or shut down.
Apparently these symptoms indicate that a low-level component of Mac OS X, lookupd, has hung. Since lookupd is used by many other parts of Mac OS X, it effectively hangs Mac OS X itself.
If this sounds like a problem you are having, try the steps in the following link to fix it.

Hope it helps,

Hi Bee,
There is indeed "such a bug", though you may be fortunate enough to not be affected. Unfortunately MANY others are affected by this. I spent three days helping track this down (many of those 38 posts were while tracking it down in the Tiger discussions) and find a fix to this and thought that others might benefit by my efforts... By the way it's NOT a Safari bug, it happens in any browser, it's a "lookupd" bug which may be triggered by surfing to certain sites which contain links to "js.adsonar.com", which if you have JavaScript enabled can hang lookupd and take down your entire system... consider yourself lucky that it hasn't happened to you...
Here is some background information if you don't believe me:
Apple Discussions: "Fixes" for lookupd Problems, some via Java Updates
Apple Discussions: System unresponsive within the last week
MacFixit Discussions: Progressive Freeze and Network Access under Tiger
MacFixIt Special Report
MacFixit Follow-up: Another fix for system-wide freezes when Web browsing
I only posted this fix to the specific threads where people were having Safari hang, incase it might help them. Forgive me for trying to help them... I thought that was the point of these boards and that was why they started threads about their issues... I'd be willing to bet that this fix will indeed fix many of their problems...
I also posted one additional new topic here on the Safari board and one on the Tiger board for new readers looking for solutions to the same system hangs they may be getting while surfing.
If this fix does indeed help any of you other readers, please post back here so that Bee can indeed see that I'm not just posting here to waste my time...

Is the 1.0 downgrade a definite fix?

I'm thinking about downgrading to 1.0 from 1.1.
Cause i'm getting the "silent" movie effect after a movie is playing.
Is the downgrade a definite fix for the problem? Has anyone still gotten the problem after the downgrade? do i need anything in1.1 that is not in 1.0 besides the radio remote drivers?
Thanks

For what it's worth, this cannot be a solely "1.1" issue. My new 5G came with 1.1 already on it and has worked flawlessly with every video I've thrown at it - ripped DVDs, music videos from iTMS and stuff I've transcoded usign iSquint (some of which started out as .mov, .wmv, .rm, .avi or .vob files).
It's either a glitch picked up due to playing some oddball files, a hardware issues with a subset of iPods or something else, maybe related to the 1.0 to 1.1 upgrade process. It is NOT universal with all 1.1 users.

Fix for iMessage banner notifications in iOS 8.1 freezing the keyboard or touch responsiveness?

Is there a fix for iMessage banner notifications in iOS 8.1 freezing the keyboard, and making the phone non-responsive while receiving messages?
I have a Verizon iPhone 6 - 128gb Space Gray
While I'm receiving banner notifications for iMessage, my phone will lock up until the notification banner clears. If I'm in the middle of typing, the keyboard will lock up and then resume back to normal once the banner goes away. No matter what task I'm doing with the iPhone, it will freeze up until the notification goes away. The touch screen becomes unresponsive. To be clear, the banner notifications are not freezing themselves. They go away on their own. But while they come in, it renders the phone useless for that 3 second time frame.
The only temporary fix I've found for this issue is to turn off iMessage notifications all together, or just turn off banner notifications for iMessage. This has to be a software issue in 8.1 and needs to be resolved ASAP.
I've troubleshooted every known possibility.
* Reset network setting = Didn't work.
* Reset all settings = Didn't work.
* Wipe Phone completely and start as new (did not restore from back up) = Didn't work.
* Restore as new from iTunes (did not restore from back up) = Didn't work.
* Visited apple store and received a replacement = Didn't work.

Jeez, the keyboard lags behind so much and the keys seem offset

After updating to ios 5, my calendar sometimes freezes when entering a new event. I have tried syncing but it doesn't fix the problem. Are there any bug fixes for this? Any ideas would be great thanks, I don't really want to have to reset everything!

Try to reset the iPod by pressing the home and sleep button for about 10sec, until the Apple logo comes back again. You will not lose data doing a reset, but it can clear some glitches after installing new software or apps.
