High CPU use (sorry for cross-posting this one)
I've posted this under general here: [High CPU Use? |High CPU Use? ] but think maybe I should have posted in this forum.
Any help much appreciated.
Edited by: Lee Furness on Apr 21, 2009 2:03 PMI just posted a reply in the original thread, I guess it's easier to follow this if you have question and answer in one place.

Yet another high cpu using flash issue
Salutations. What I'm about to tell you won't come to you as a surprise as there have been many similar topics discussed here. In fact, on the first page, there were two. So let's get on with it!
hp pavillion entertainment notebook dv6 e2170ee
windows 7 64bit
6gb ram
intel core i7 cpu q 720 @ 1.60 GHz (never overclocked. don't know how to)
nvidia geforce gt 230m
firefox is on safe mode. kind of better than regular mode.
firefox waaaay better than chrome in handling flash. haven't tried it on ie. don't want to. i left ie8 at version 8
flash hardware accelration is off
firefox hardware accelaration is on
latest flash player enabled
latest shock player enabled
latest flash director enabled
latest firefox
no idea if my vents and cooling system work properly. read several posts about this issue being related to hardware.
i have updated my drivers using hp support assistant, driver detective, and windows update. wouldn't be surprised if there was a conflict with all this nvidia driver as well. went to the site. it detected my model and sent me the driver. had audio and video options in it.
while writing this post, the adobe tab + 4 flash tabs off the same site (youtube, younow, cam sites, etc) are open.
performance tab in taskbar says
flashplayer 15 *32bit (2 processes with the same name but diff cpu usage by the way. why 2?) is using 5%
firefox *32 bit is using 5%
audiodg.exe is nowhere to be found
now firefox and flashplayer keep alternating ofcourse. flash always ends up with higher cpu when everything breaks. i have noticed that even after closing ff, ff and flash are still in the processes table. they stay there for a bit. why?
ISSUE NUMBER 1: i can't play a video and have flash players on at the same time. I'd like to watch a movie and every now and then look to my other screen to see what's going on with the flash site. it can't be done. all is well at the beginning then it goes to hell. i have the latest free version of bsplayer and videolan. Yes vlc handles better but it all goes to hell in the end. sometimes the video won't even show on vlc; only audio
ISSUE NUMBER 2: i don't understand the logic behind the increase in cpu. if i have 6 tabs open all flash all is well. but at some point it just spikes up. so i always try to keep the number of flash tabs as low as possible. sometimes 4 are no issue but 5 are a big issue. sometimes closing a tab helps and sometimes it doesnt.
ISSUE NUMBER 3: audiodg starts using more than 2%. It can go up to 11 or 13 even. That shouldn't happen. I've been told that for it to go beyond 2 or even 3 means there's a conflict. I had trouble dealing with this issue. I don't know what or where the conflict is. So if there's anyone here that's good at this please contact me. Ill post a pic of device manager. For the sound, i have 4 nvideo and 1 idt audio codec. I cdon't know which to disable or uninstall. im thinking of unintalling every audio/video driver i hav and start from the beginning. BUT LETS NOT MAKE THIS ABOUT AUDIO/VIDEO CONFLICT
QUESTION 1: was there ever a time when this issue didn't exist? perhaps there's a "stable" version of ff or flash that don't cause this.
QUESTION 2: ive seen a lot of posts about this but I honestly can't remember any participants saying OH REALLY? ODD, I NEVER HAD THIS ISSUE BEFORE
QUESTION 3: isn't there some kind of tracer that can track the moment that it goes to hell? im sure there is but no one's mentioned it so far
QUESTION 4: would buying a new laptop solve this? I'd like to think not since the issue is flash not the capabilities of a laptop but i can't help but think that a better laptop will fix this. My laptop is 4 years old.
QUESTION 5: i don't know anything about multithreading or multiple cores handling a single process but if someone showed me how, would that resolve my issue?
MY WISH: for flash to coexist peacefully with human beingsDisabling Hardware Acceleration in Flash means that we're doing all of the processing on the CPU, instead of on the GPU. The GPU is purpose-built for 3D graphics and video decoding and is far more power efficient. Decoding H.264 video in software is very CPU intensive, which is why we made the huge investment to enable hardware acceleration on the vast majority of available desktop hardware. Running six CPU intensive tasks simultaneously (which is what you're doing by using six simultaneous tabs) is unsurprisingly going to tax your machine.
If you've disabled Hardware Acceleration because video wasn't working right or something, figuring out how to get that enabled (or moving to better hardware with good driver support) would solve the vast majority of what you're describing here. If HP doesn't offer updated drivers, I'd recommend trying the corresponding Nvidia drivers, as OEMs aren't always motivated to pick up the latest fixes once a model is no longer generating new revenue for them. The chipset manufacturers tend to provide longer support, but those drivers aren't officially supported by the OEM.
The architecture for Protected Mode for Firefox is a result of the fact that we've retrofitted a modern plug-in security approach to a legacy plug-in architecture. As you've noticed, equivalent sandboxing in other major browsers is designed into their plug-in architectures, and is therefore more efficient. We've made huge investments to support modern security architecture and always do our best to accommodate efforts from our partners in the browser space to further secure the browser. You can find a detailed explanation of our approach to Firefox here: Inside Flash Player Protected Mode for Firefox
Firefox controls the instantiation and destruction of Flash instances. You'll also notice that Firefox hangs out for a while after shutdown. This is something that we're aware of, but it's beyond our control.
Flash doesn't have much to do with audiodg, except for the fact that it generates sound and uses the windows sound subsystem. This article seems to present some reasonable advice in resolving issues with high CPU consumption from the sound subsystem. Fix Audiodg.exe High CPU Usage in Windows 7 | Windows EXE Errors
Hardware accelerated video encoding is typically not available on consumer-grade hardware (primarily because of the difference in licensing models for encoding and decoding with popular commercial codecs), and therefore is done on the CPU. The particular website chooses what codecs and bitrates are involved, and higher quality feed will consume more CPU. It's also worth pointing out that not all video can be decoded in hardware. We provide clear guidance to content providers on how to encode video so that it can be played back efficiently, it's ultimately up to the content provider to follow that advice.
So, long story short, each tab consumes resources. Running a single tab is going to use less resources than running multiple tabs. The latest version of Internet Explorer does some stuff to reduce resource consumption in tabs that you're not actively looking at. We're discussing possibilities with the Chrome folks for doing the same thing in Chromium-based browsers. Mozilla isn't interested in investing in browser plug-ins, so we don't expect to see the necessary browser-side improvements there. The Chrome sandboxing model is more efficient that protected mode for Firefox, so tasks that require moving a lot of data (like streaming video) may use less CPU in Chrome.
To answer your questions specifically:
1.) There was a time before we supported multiple tabs, webcam streaming, H.264 video decoding and modern security sandboxing. I wouldn't recommend using those versions.
2.) There are a few posts about this, but we have ~1.5 billion users. The majority of the very small number of folks relative to our install base are complaining their machines are overheating, which is a symptom of an ineffective cooling system.
There's nothing magic about Flash that causes it to somehow superheat the CPU.
There was a time before tabs, where people didn't normally run 5-50 browser windows. Websites also got much more complex, and the security threats got far more serious and complex.
Playing video as a plug-in in the browser as opposed to something like VLC is inherently less efficient, as pretty much each pixel and packet gets passed through the browser before it gets to the OS or drivers.
All of these things require additional processing. The resources on your computer are still finite, and there is an upper limit to the number of simultaneous tabs you can use.
At some point, you come to a juncture where you need to decide between throwing more hardware at the problem, or using less tabs simultaneously.
Also, most laptops have power saving CPUs, so they'll ratchet the clock speed down to save battery. You might want to check your power settings to make sure you're running at the CPU's full capacity when plugged in.
3.) Not that would generate anything really useful.
4.) Possibly. You actually already have a multi-core machine. I think you'd get more bang for your buck by enabling hardware acceleration and switching browsers.
5.) You already have a multi-core machine that we support.
Your Wish: We're constantly addressing security issues identified through our own testing, emerging research and intelligence from our partners in academia, government and industry. We're also looking for opportunities to tune the player, but the reality is that Intel, Nvidia and ATI (and a long list of others, in addition to Adobe) have tuned Flash Player extensively for their hardware. We work closely with the Internet Explorer and Chrome teams to continue to make the Flash experience better, and are always happy to work with the Firefox team should they decide that they're interested in plug-ins and the desktop browser again. At the end of the day, Flash is just a low-level runtime. It's just as possible to write inefficient ActionScript as it is to write inefficient C++, and while we provide some fantastic tooling for profiling your Flash content, it's up to individual content providers to write efficient code. It's really difficult to find opportunities to make generic optimizations that don't break a percentage of the hundreds of millions of sites published with Flash content.
I'm actually still not clear on what the problem you're experiencing is. All software running on your machine that's actively processing something is going to use a non-zero percentage of CPU time. The symptoms you describe indicate that Flash consumes 5% of the CPU, which is totally reasonable. I'm guessing that I don't have the complete story. -
I have searched the discussions and tried all the suggestions and am not having any luck decreasing the cpu use of mail. As soon as I open the program it starts increasing the cpu usage until it hits high 80's. I eventually have to quit just to quiet down the computer due to increase in fan noise.
I have trashed the preference file. Rebuilt all the mailboxes. Emptied the trash. Run disk utility.
I can not think of any reason for this to just have started happening. I have not done any new installs. Does any one have any suggestions?
Thanks...LennySo...what does this mean?
It means there is something about your user account that is the cause of your CPU usage for Mail, not Mail itself. Did you install any software just before this started happening? If so what was it, specifically? Try this to see if it makes any difference:
Quit all applications and use Disk Utility to Repair Disk Permissions. Ignore any messages about SUID or ACL; it means nothing. Quit when it's done. Next, go to ~/Library/Caches/Mail and delete the contents of that folder, then use Get Info to Lock the folder.
Also, if you have any Bundles installed for Mail at ~/Library/Mail, disable them and then restart Mail to see if the problem continues. -
Hello,
since I upgraded to Mountain Lion 10.8.4. and iTunes to 11.0.4 a couple of days ago, iTunes keeps fooling around using up to 130% of my CPU (how is that even possible?!) when playing music. As soon as I pause the music, the CPU-use goes back to >1%. Before the upgrades I had a big library with over 170GB of music (no only a few albums) and no problems using iTunes whatsoever.
I run a mid-2010 13" MBP with OSX 10.8.4, 2,4 GhZ Intel Core 2 Duo and 4GB of RAM.
Thanks in advance!Yessss! i' ve finally found the issue !
The problem was with "smart play lists" i dunno how you call it in english, but i' ve created a long time ago a smart playlist named "unread" because the "all random" function is not so much random for me, as they play some tracks more often than others...
With as criteria " numbers of play = 0 " so one title is played one time!
By using my brain as good as i can, i told myself " what itunes do when a song ends and then go to the next?"
It wrote something on the smart play list or something like that
Then test from "play all random" = no more issue !
Then deleted my smart play list and recreate one identical = problem solved !
norbml : i hope this help you -
Macbook Pro "not charging" during high CPU use
My Macbook Pro Does not charge when I am running several small programs (or one large one). My charger will change from the orange "charging" light to the green "not charging" light a few seconds after I begin running a program or set of programs that have a combined use of over 30% User CPU. Once I close enough programs to drop below about 30% User CPU, the light switches back to orange and begins to charge again.

<Edited by Host>How's the light on your power cord, on the receiving (your Mac) side? If it shows green, don't sweat, it means it is charging alright, no matter what the battery meter in Windows says: battery management is largely firmware-run on a MacBook Pro, since it's not exactly supposed to run another OS than Mac OS X. If the light shows yellow/orange, then for the sake of experiment, let it run until your battery dies. If it does at all.

High CPU using process slowed down after a period of time
Hi,
I am running a Finite element commercial solver, our tipical installations are with windows server 2008 but now we were force to move to windows server 2012.
When we launch the solver, which may be working with up to 20 cores, the CPU usage remains consistent for about 40 minute/1 hour then drops to the usage of only one core without having completed the process, which complete several hours later.
We already tried putting the power management at High performance, but didn't solve.
Are there any suggestion regarding where to look at?
Thanks
RaffaelloHi,
First, please make sure your hardware support windows server 2012. I’m not sure what “Finite element commercial solver” is. So I just treat it as a kind of software. Is there
any compatibility with the software with the new OS?
Process Monitor may help address the issue.

High CPU using on transcoding - Build Progres not responding
I have a PAL Widescreen Encore project. Most assets are from dynamic links with Premiere sequences. The Premiere sequences are of Matrox HD 1080i50 type. The material is HD422 and HDCAM EX. One timeline is about 3:30h and the other about 0:20h.
The DVD is authored and I want to build the disc to a folder. I start the building process and the Build Progress dialog comes up. It shows that it is transcoding. After a while, the progress bar for the transcoding of the ...prproj(Video) file stops moving. The bar shows about 10% of the total length. When I click on the Build Progress Window it shows "not responding".
The CPUs are almost always between 97% and 100%. Every few minutes CPU goes shortly down and then up again. Memory using was most of the time at about 11GB of 12B total. Shortly ago it dipped to 8GB. Encore-exe uses between 92-97% of the CPU time. PremierePro.exe uses about 1-8%.
I would like to know if this is normal? I wonder if the render will finish some time or if Encore just hangs. I especially never had the issue that the Build Process dialog was not responding or updating. Could it be that the progress bar will update after the long sequence is rendered, but not before? I tried to have the project rendered last night already. The computer was running for about 7 hours and the bar was as now stuck at the beginning. I then rendered all the sequences from Premiere with AME directly into MPEG-2. It toook about 6 hours for the complete material.
I think I have an i7CPU with 4 CPUs and 4 Hyperthreaded CPUs, NVDIA Quadro 4000, 12 GB RAM, Win 7, ASUS board, CS5 Master Suite.
MarcusWhen I originally tried to export directly from Premiere my 3:03h long footage was extimated to render for 36 hours! I expected Max Bit Depth to cause this delay. Because my only transitions are fades I turned it off. The render was done in about 4 hours, which was reasonable. Since the render via dynamic link in Encore was not working properly, I tried to export the footage again directly from Premiere, because I originally forgot to export the audio as Dolby. This time even the direct export from Premiere was estimated at 36 hours having Max Bit Depth turned off. This puzzled me. When I expoerted the first time I did a direct export. This time I tried to use the queue. I exported again uaing the Export command and voila the export is estimated at about 4 hours.
Why does it take about 9 times longer to render using the queue instead doing a direct export from Premiere? I know this question is pobably better placed in the Premiere forum, but it for sure is also the source for the long render times doing the render with the transcode command in Encore. Searching on the Internet I found this:
http://www.dvinfo.net/forum/adobe-creative-suite/491220-export-vs-queue-great-difference-p erformance-2.html
I have to re-read it when my brain is rested. At the moment I don't fully understand why apparently CUDA is not used on Queue rendering on my system.
Some general insight can be found in the Adobe blog: http://blogs.adobe.com/premiereprotraining/2010/10/scaling-in-premiere-pro-cs5.html and in http://blogs.adobe.com/premiereprotraining/2010/07/maximum_dimensions_in_premiere.html.
It still doesn't explain the big difference between Queue and Export on my system. -
Yosemite Mail.app High CPU Use
Since upgrading to Yosemite, Mail.app frequently spikes multiple cores for an extended period of time. Even background mail checking spikes the CPU load.
Seeing the same issue. The problem, in particular, relates to email sent to me from another Apple Mail user via Exchange. I can view the email on my iPhone or iPad, but not in Apple Mail.
I think, from what I can see in the crash logs, it relates to parsing attachments. (which may just be things like email sig blocks)
Sending my log to Apple Bugs -
Hi, I recently installed Animate 3.0. Unlike 2.0, my cpu use goes very high doing the most basic of things like double clicking into a symbol to edit. I have a 1 year old high spec laptop with Intel i7, 8Gb RAM, GTX 765M graphics and Windows 8.1.
No other application causes such high CPU use.
It also takes the stage area at least 0.5 seconds to reload itself after each save. If I am several levels deep into nested symbols, on save, the stage will display the top level and then repaint to my current level.
Has anyone else experienced this?
Cheers,
PatrickYes. It is a HUGE resource hog. I am running win7 64bit with pleanty of HD space, a high-end gaming graphics card, and 16GB ram. It takes a lot of time to enter a symbol (sometimes more than 5 seconds), more time to save, and sometimes brings my computer to a standstill for over a minute. Oh, and Edge also crashes completely on occasion when trying to save or enter a symbol... I hope Adobe fixes this, but I am a Flash developer moving to Edge, so I expect poor-preformance with memory and cpu. Works better if you don't test in firefox. Also exit completely out of the code editor before saving, that helps the save problems.

Major issues with plugincontainer.exe using high cpu freezing firefox 34
Plugincontainer.exe is ruining my experience with firefox by constantly causing it to freeze due to high cpu use. Please advise of a work around or other solution. Thank you.
The only solution I have found was to downgrade to Firefox version 30.
The odd thing is that the high cpu does not happen on all web sites. wsj.com (Wall Street Journal) is fine, but cspan.org is not.
My PC does not freeze up, but it has a sustained CPU usage of 70 to 80 percent. I am running an Intel Dual Core on Windows XP.
Is this the case that my CPU is just to slow? This should no be the case since version 30 runs at the regular 15 to 30% usage.
Forgot to mention that this is the Adobe Flash player that is causing the high CPU readings.

Attn: ALL APPLE PORTABLE OWNERS -MacBook Pro, MacBook Air, Mac mini slowdown kernel / high CPU use problem and solution.
YOU COULD FRY YOUR COMPUTER IF YOU DO NOT FIX THIS PROBLEM SO PLEASE READ THIS ENTIRE MESSAGE!
YOUR MAC WILL THANK YOU
Hey all.
Like many of you I've got a newer Apple portable which slows down to an unusable level for an unknown reason. In my case a 13" mid 2009 Intel MacBook Pro Core 2 duo laptop. After many failed attempts to figure out what this nutty problem is I have discovered the problem, the solution and I have solved this for my own MacBook Pro. Since this fix it has been working immediately and consistently -without issue
I am sharing this with you in hopes that you to can fix your Apple portable yourself or so you know what to tell the Apple techs so they can quickly fix your Mac from this wacky and unfortunate kernel CPU hogging problem.
User Software Symptoms :
Your Apple portable computer periodically for an unknown reason slows down making everything frustratingly slow. This happens even when running previous apps that were never a problem; things that your Mac should be able to handle easily but for some reason now it can't.
Slowdown most often happens during high CPU use such as gaming, video playback/editing, etc. or when running multiple apps (even non CPU intensive apps) at the same time.
Possible Hardware Symptoms:
Your computer is making more noise than it did previously.
Your computer occasionally makes more noise but then gets quieter.
Your computer is always extremely quiet (too quiet) even during high CPU apps -worst case scenario.
It feels hotter than it normally does. Test: After several minutes of the slowness/high kernel CPU touch the computer to feel if it's hotter than normal.
Looking at Activity Monitor (in the Utilities folder) shows the kernel_task is going bonkers eating up CPU but you have no idea why.
After trying many different things to solve this problem such as :
PR ram reset, SMC reset, fresh OS install of 10.5 and 10.6 on external hard-drives, calling and speaking to various Apple tech people who had no ideas/solutions, etc. I had no luck.
Btw, if you're having the symptoms I've decscribed above I would not run the Apple Hardware check (read below as to why). You could fry your Mac!
After much testing I found the problem :
It is my belief that "recent" Apple portable computers are using low quality internal fans which soon stop working!
Fail time period seems to be about 1.0 years to 2.5 years of use but this fail rate could vary depending on use.
First noticeable symptoms (depending on what you notice) could be computer slowdown or your fan is making more noise than it normally does. This is your fan's lubrication slowly eroding making your fan spin slower and less smooth resulting in the louder noise and slower rpm spin speed. The slower fan spin speed means less cooling is happening for your computer. The effect on your computer is that the CPU and other chips are heating up! Overheating to be more specific. When your computer's chips overheat they get wonky and screw things up. Most often this seems to have the effect of making the kernel hog CPU resulting in a frustratingly slow user experience! Heat kills computer chips and it is extremely bad for them. Extreme overheat or repeated overheating has been said to shorten the life of computer chips or in extreme cases even fry them completely!
The longer this goes on without being fixed your fan loses more lubrication and spins slower and slower cooling lesser and lesser resulting in your CPU heating up more and more possibly shortening the life of your Mac! Eventually your fan will stop completely and you could fry your chips! My fan stopped completely and my MBP was running very quietly, too quietly. Luckily I did not fry my chips because I was avoiding using high CPU apps because I knew something was wrong due to the massive slow down and wonkiness when I'd run them.
Side Note:I'm a bit concerned about all those Mac mini servers which may be using the same defective low quality fans which cannot be easily serviced by their owners as they are co-located in some server facility. One positive thing is those facilities are usually well airconditioned keeping temps low.
I suggest you do not run the Apple hardware test if you suspect your computer is overheating because the hardware test can seriously heat up your Mac! I tried running this test and my Mac got so hot I had to shut it down forcefully and I was concerned I damaged the chips. If you want to run the Apple hardware check make sure your CPU temperature is ok and that your fan works well before you run the test.
IF YOU DON'T FIX THIS PROBLEM YOU COULD FRY YOUR COMPUTER DUE TO HEAT DAMAGE!
DO NOT IGNORE THIS PROBLEM YOUR MACS LIFE MAY DEPEND ON IT!
First you need to properly diagnose this problem and see if your CPU is getting to hot and you need to see if your fans are spinning at high rpms giving proper cooling, or if they are spinning at low rpms when running high intensive apps as your CPU temp increases.
TEST IF YOUR FAN(s) IS WORKING CORRECTLY :
Unfortunately Apple does not include CPU temperature reading software nor fan rpm speed software that I am aware of.
However, There are two free ways that I know of to check your CPU tempurature and your fan speed :
One app shows fan speed, and CPU heat, etc.
One app shows fan speed, CPU heat and allows you to adjust your fan speed settings.
One app is a dashboard widget, the other is a system preference.
I suggest you download both of these to check your computer statistics.

I am not exactly sure what proper CPU temperatures are for the different Apple computers and this will change given different CPU loads.
My MBP doesn't seem to function properly with anything around 90 degrees or higher (celcius).
It seems when the fan is operating normally the CPU temp should not stay above 78 degrees even under heavy load, at least with the apps I'm running in the room temperature I'm in.
I can post back later with more specific temps under longer load, etc. but I wanted to get this post up for people to read as soon as possible so they don't fry their Macs.
If a bad fan is your problem :
THERE ARE ONLY TWO SOLUTIONS FOR THIS PROBLEM :
Fix or replace your fan so it cools the CPU and other chips properly.
I fixed my fan myself and I didn't need to buy a new one. Total cost was about $8.00 because I had to buy a #00 sized screwdriver and had it shipped to me. Price includes shipping.
On my mid 2009 model MacBook Pro fixing the fan was incredibly easy :
Before I started doing this I wasn't 100% this was the problem so I decided to try to fix my fan instead of ordering a new one and replacing it. As it turns out I didn't need a new fan, I only needed to clean the existing fan and relube it's axl so it could spin easier like when it was new. It also didn't make sense to buy a brand new fan from an Apple authorized parts reseller selling me the same low quality fan for $49.00 which would probably fail in 2 years again. Prices for new comparable fans from different manufactures range from about $15.00 USD + shipping to around $49.00 USD + shipping depending on where you order them from and what brand you get.
How to fix / replace your internal fan on a mid 2009 MacBook Pro :
Please note : I am not a hardware technician, nor expert. If you decide to fix your Mac yourself you do so at your own risk through no fault of my own. Prior to opening up your Mac you should google around and learn how to do it correctly and safely so you won't damage your Mac. For example, it is possible for you to damage your Mac by static electricity from your body. To avoid this I believe proper procedure is that you wear a 'ground strap' (around your wrist) which you clip to your Mac's metal body so your body will not excude a charge into your Mac. I believe the idea here is to keep your body's charge level and your Mac's similar. Since I do not have a ground strap and fixing/replacing the fan doesn't require touching any chips I did not wear a ground strap during my fan fix. What I did was periodically repeatedly touch the metal case of my MBP hoping that would be enough and it was. Avoid unecessary actions that can build up a static charge in you. Once I started the repair I did not walk around the room building up an electrical charge in my body. Walking on carpet can often build up a large charge in us so it is better to be avoided while working on your Mac. Certain clothing can build up static charges. Combing hair, etc. If you need to get up from your repair when you come back make sure you first touch the Mac's metal case and not anything inside.
Now that we're done with the scary paranoia, below you will find some instructions on how I fixed my MBP's internal fan
Before you begin:
Check out someone's video (not mine) on how to remove / replace the fan (but not take it apart and repair it):

How to repair your mid 2009 MacBook Pro fan:
Make sure you are in a 'secure' environment. No pets, no kids running around, no drinks near the Mac, etc.
Make sure your computer is unplugged from it's power supply and turned off. NOT slept. Totally off / powered down.
1. Get a size #00 phillips screwdriver (Hobby store, Radioshack, Amazon).
2. Open up your MBP by unscrewing the bottom (yes flip it over so it's resting upsidedown). Note where each screw goes because some are different lengths. I placed each one around my MBP where they go, insuring I know their order (don't jumble them up). Note which direction your MBP is facing when it's upside down so if you spin it around while working on it you still know where the screws go.
2b. Some recommend removing the MBP's battery but I didn't do this step. You probably should, just to be safe. Follow the online instructions from the web page I listed about disconnecting the battery.
3. Unscrew the fan's 3 holding screws.
4. Unplug the fan's electrical connection (lift it straight up off the board). If you need to you can try to pry it up while you lift with a non metal/non electrical conductive object like a spudger if you have one or -perhaps a pen cap. Before you remove it, look closely at how it's attached so when you put it back on you won't wonder if you're doing it correctly. There's only one way it can go because it cannot fit 'the wrong way' but looking at it closely will make you feel more confident popping it back on when the time comes.
5. Remove the fan - it easily lifts out.
6. Take the fan apart by unscrewing it's one screw then unlatching the plastic clips which hold it together.
7. Seperate the fan blades from the housing. Lift the fan blades off of the fan housing by pulling it straight out away from the housing.
8. Clean off the dust that's gathered. A can of compressed air helps here (I didn't have one). I used a little brush from my electric shaver kit which worked well. Once you've removed all the dust from the fan and surrounding areas proceed to the next step.
9. Reapply new lubrication. You need less than 1 drop. Be sure it covers the entire fan blade axl as this is what needs to be well lubricated. Make sure there isn't excess oil that will fly around when the axl/fan spins at high rpms. I used the only oil I had which was olive oil (for cooking!) but I do not suggest this. At the time I was doing this I didn't know my fan was the problem so I wasn't even sure I was going to relube it. You should probably use something more appropriate perhaps like 3 in 1 oil. A good idea would be to call the manufatures of these little fans and ask them. Maybe a hobby store knows of good lubricants for these purposes?
DO NOT use things like WD 40 as it's not a long term lubricant or so I've read.
10. Once your fan is now clean and oiled (make sure there isn't too much oil) reassmble the fan.
Push the fan blades/axl back into the housing shaft. Give it a few spins with your finger.
Screw together the fan housing then reclip the clips.
11. Place the now reassembled fan back into your Mac and screw it in place (3 screws).
12. Reattach the fan's electrical wiring by gently pushing it into place. Make sure you've got the right end facing down before you push it in place.
13. Once your Mac's internals are clean and reassembled, place the rear cover back on your Mac and screw it in place.
14. Double check you didn't forget anything like screws, tools, etc.
15. Boot up your Mac and monitor the temperature and fan speed using those programs.
Compare the previous temps/fan speed to the current temp/fan speed.
Run a high CPU intensive app where your computer has been slowing down.
You should now have a happy Mac
If you have this problem and this solution fixed it for you please post in this thread letting me and everyone else know!
Hope that helps.Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

Jcaps 5.1.3 - high cpu usage eventstore.db
Hi,
JCAPS 5.1.3 on windows 2003 -
I'm witnessing some persistant high CPU 30 - 40% usage and constant access to the file eventstore.db.
Is this normal behaviour or is there a configuration option to reduce the polling frequency on this file?
Has some alert gone wrong?
Actually user usage is very low - practically none.
ThanksHi,
I noticed this behavior with the Alert + SNMP Agents installed but not configured. In this situation, the SNMP agent generates traps for all events, leading to high CPU using, even when nothing was processed. Are you in a similar case?

MACFLAPS seen only on 1 vlan and also has HIGH CPU HULC LED PROCESS
Hi All,
Their is a weird problem we are having with MAC-FLAPS and HIGH CPU uses. The odd think is when we change the VLAN on the port to a different one then the flapping stops but when we turn it back it starts again. I removed the Vlan from a switch (3750) and the CPU usage returned back to normal even though it was only using it for a printer only (was 50%/30% cpu!).
However the problem now exists with TWO 2960 PCS and 1 2960 POE and they have HULC LED PROCESS at 65%/40% plus CPU usage. There are no STP or HSRP issues on that VLAN however I think it's related to that VLAN. I even backdated the IOS version and reloaded but problem still persists.
What else can I do or is the switch gone (memory leak?). I don't to change all 3 switches so how do I know which switch is the cause as the CPU to be High and only caused due to 1 vlan? ALso when we put something on that VLAN sometimes we get MACFLAPS; although if we change the VLAN the MACFLAPS stop. But the Macflaps are intermittent so I really am not sure what the problem is.Hello.
Regarding "Hulc led" process - it's a bug; please provide the IOS version you are running.
It's not clear waht issue do you have with MAC flap; could you please provide command/log outputs? -
High CPU usage when importing CDs. HELP.
Help me! Whenever I try to import CD's or music on to itunes, it automatically spikes my CPU usage to 90-100% and usually stays there, hogging all the activity on my system and making my system run incredibly slow. It also slows down my importing speed to sometimes 0.9x. Which is incredibly frustrating. Also, it is really starting to worry me because sometimes my computer will just shut down without any warning because it is being overworked. Does anyone else have this problem or have any clue what to do? I am afraid it may eventually cause my entire system to crash or something terrible like that. HELP ME!!!
High CPU use should not shut down the system. Yes it produces more heat but if your system has proper cooling then it shouldn't matter.
Look aroung about slow importing. There has been many threasds on this issue here. One workaround is to not watch the progress if the importing, i.e. change iTunes focus to library or store. This has helped many people.

The days are gone when a customer service manager could actually serve the customer.
I can remember a day when asking to "speak to a manager" actually meant you were talking to someone who the company entrusted the authority to think outside box and take care of a customer. AT&T has created a system where there is no real authority.
