Qosmio X775 - CPU usage is over 99%

I have a Qosmio x775 and while (im not gonna lie) i was playing LoL, somehow evverything started to go slower. My mouse barely moved, so i quit everything and turned off my qosmio.
Then i turned in again and the problem got worse.
It took like a minute to open the start menu. So i opened the task manager and watched the cpu usage went from 24% to 99, 100%,
So i started to end useless, yet cpu consuming processes and somehow my laptop went back to normal.
I'm about to scan it with my antivirus and im gonna erase stuff i dont need, but i just want to know what could happened and how to avoid it when it happen again?

I agree with Joe.
Have you noticed this from the first day of usage or later?
What you can try is to stop some useless background processes to see what will happen after doing this.
Which antivirus application do you use?
If you use original preinstalled OS disable or stop Tempro and Toshiba service station tool. They are pretty active in the background. Original preinstalled McAffe needs much resources too.
Play a bit with all this stuff and check in task manager which application or process make CPU so busy.

Skype CPU usage over 75%.

When i use skype, CPU usage is over 75% (activity monitor).
Is this normal ?
(MBP 2011)

No, that shouldn't happen. Try uninstalling Skype completely (with AppTrash or TrashMe), then reinstall the latest version.

SL510 CPU usage

I have here, side by side an Acer laptop running Windows 7 64-bit and the Lenovo SL510 running the 32-bit version. Task manager shows the Acer using between 0% and 3% cpu when idle, the Lenovo shows between 51% and 100%, with one core always seeeming to be revving away.
If I look at the processes tabs in each machine, they are similar, with just one or two processes popping up to 1 or 2 %. The Lenovo does not show any process or combination which could add up to more than 2 or 3%
The Lenovo does not run hot, but I am concerned that something is not set up correctly. Can anyone advise?

It appears that the standing cpu usage of over 50% has been reduced to about 1% by discovering that uncserver was running and stopping it.
I think this can only have come from some sort of problem with one of the Lenovo ThinkVantage tools, so I rebooted everything and then ran the Lenovo Updater. I have now updated three times, rebooting each time.
Each time it says it has updated the Intel Matrix driver and some other updates, and the update is listed in the Update history. However, when I run the updater again, it says the update still needs to be carried out.
I have already had to disable the Access Communications application because it forced Internet Connection Sharing, which I needed to remove. These tools seem to be a good idea, but I have never had this much trouble with the setup of laptops in the past.
Would it be sensible to remove the Tools altogether?

High CPU usage on WS-3560G

Hi All,
I'm experiencing constant high CPU usage (90%) above on a 3560 switch. I have rebooted the switch. The problem persists. I've had a look at the 'show cpu processes sort' command and I have observed 'FIFO error Detec' is using more than 7% of the CPU.
Has anyone experienced this before? I've never seen the 'FIFO Error Detec'

Hey Martin,
When you see there Fifo Error Detection than you have to think that there is something wrong with the queue on one of the interfaces so I suggest looking for that interface. Moroever you mentioned that CPU usage is over 90%, so you may have to check other processes as well.
HTH.

Mac goes over 100 percent cpu usage

As seen in the picture, the game called 'runescape' which i was playing reached 171 percent cpu usage on my computer. My computer never crashed from playing this game but crashes alot while playing Dota 2, once when I crashed from dota 2, the computer lagged showing my activity monitor which showed that dota had 100.1 percent cpu usage. Is this a problem of the game or the computer? Multiple friends of mine have played this game and never once crashed on it.

It is a problem with games in general: they use a lot of CPU power (and heat the CPU up correspondingly). Over 100% is not very spectacular, because modern CPUs have 2, 4 or 8 cores, and each has a maximum of 100%. If you have a 4 cores cpu the run escape is taking almost 45% which is a lot.

I followed these instrucitons and the worked perfectly on my HTPC build (running the AMD APU A4-4000 on a Gigabyte GA-F2A88XN-WIFI). I have a quick question though. When I want to shutdown or reboot I hit the power button on the lower left of the XBMC main window. Usually a dialog menu pops up giving me the option to Suspend, Shut-Down, Reboot... etc. etc. The menu in the xbmc-xvba build only shows "Exit". How do I enable these other options? I'd like to at least be able to shutdown or reboot from within XBMC.
EDIT:
Nevermind, I solved it..
I found this thread
It says that running XBMC as a service will not register my session and polkit will not work. I have to autologin as the user xbmc and startx automatically.
I followed the instructions here and here. Then I added "exec xbmc --standalone" to the end of my /var/lib/xbmc/.xinitrc file.
Everything works fine now.

IPhoto 9.3 using over 60% of CPU usage

Sinec the upgrade to iPhoto 9.3 it hogs CPU usage over 60% getting beach balls etc.
I have to quit just so I can use the Mac with other applications.
OS 10.7.4 8GB RAM 400GB free on HD new fitted only a week ago.
I do use Aperture and they share a library.. Anyone having the same issue? or anyone
with any suggestions?
Cheers all,

Make a temporary, backup copy of the library if you don't have one (select the library and type Command+D) and apply the fix below:
Fix
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Since only one option can be run at a time start with Option #1, followed by #3 and then #4.
Launch iPhoto after each rebuild and see if there's any improvement.

Kernel Task over 400% CPU usage

Hello, I have some questions about the Kernel Task in my activity monitor.
Recently, after a hard disk failure, I have my Macbook Pro wiped and start afresh with Mavericks. All was well, but it slowed down tremendously in the last couple of days. I checked the activity monitor and Kernel Task is always around 400-470%, sometimes it even peaked to 1000+%! I closed all my applications but it is still taking up all my RAM. I cannot work when it is freezing up every 2 seconds. What is the problem?

The kernel is using excessive processor cycles. Below are some possible causes for the condition.
Throttling
When it gets high temperature readings from the hardware, or a low-voltage reading from the battery, the kernel may try to compensate by interrupting the processor(s) to slow them down and reduce power consumption. This condition can be due to:
☞ a buildup of dust on the logic board
☞ high ambient temperature
☞ a worn-out or faulty battery in a portable
☞ the malfunction of a cooling fan, a temperature sensor, a voltage sensor, or some other internal component
Note that if the problem is caused by a sensor, there may be no actual overheating or undervoltage.
If the computer is portable, test with and without the AC adapter connected. If kernel_task hogs the processor only on battery power, the fault is in the battery or the logic board. If it happens only on AC power, charging is causing the machine to heat up. That may be normal on some models. CPU usage should drop when charging is complete.
Apple Diagnostics or the Apple Hardware Test, though not very reliable, is sometimes able to detect a fault. For more thorough hardware testing, make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
If nothing is wrong with the hardware, then whatever you can do to improve cooling may help.
Installed software
User-installed software that includes a device driver or other kernel code may thrash the kernel. That category includes virtualization software, such as Parallels and VMware, as well as most commercial "anti-virus" products. Some system-monitoring applications, such as "iStat," can also contribute to the problem. You can test for this possibility by completely disabling or removing the software according to the developer's instructions, or starting in safe mode. Note, however, that disabling a system modification without removing it or testing in safe mode may not be as easy as you think.
Corrupt NVRAM or SMC data
Sometimes the problem is cleared up by resetting the NVRAM or the SMC.
External display
Connecting an external LCD display to some MacBook Pro models while the lid is open may cause this issue. If applicable, test by closing the lid or disconnecting the display. You might get better results with a newer LED display.

Qosmio X775-Q7170 freezes after sleep or idle mode

Hello,,
I have a Qosmio X775-Q7170, Part Number PSBY5U-03N01P<ES5.0>, running the factory installed Windows 7 Home Premium 64-bit Operating System (Service Pack 1). I have run and installed all Microsoft Updates as recommended (set for automatic download and install). I run Norton 360 Premier Edition for anti-virus, internet security, performance management/optimization, and back up.
In the last 2 months, my computer has begun freezing up when I wake it from sleep or idle mode. When this happens, I must perform a hard reboot (by holding down the power button until the device shuts down. I have tried uninstalling unused programs, I have tried reducing the number of programs that run at start-up. I have uninstalled and reinstalled my internet security software as well as running Symantec's Power Eraser Root-kit Utility. I have tried disabling my internet security suite and running other anti-virus scans and registry scans and not found any problems. I have tried running disk clean up and disk defragmenter. Viewing my performance monitor, I see that I am running about 43% physical memory usage (6 GB of installed RAM). I don't typically see high CPU usage.
Please help me.

Problem with paintComponent, and CPU usage

Hi,
I had the weirdest problem when one of my JDialogs would open. Inside the JDialog, I have a JPanel, with this paintComponent method:
public void paintComponent(Graphics g) {
super.paintComponent(g);
Color old = g.getColor();
g.setColor(Color.BLACK);
g.drawString("TEXT", 150, 15);
g.setColor(old);
parent.repaint();
now when this method is called, the CPU usage would be at about 99%. If i took out the line:
parent.repaint();
the CPU usage would drop to normal. parent is just a reference to the Jdialog that this panel lies in.
Anyone have any ideas on why this occurs?
Thanks!

1) I never got a stack overflow, and i have had this in my code for quite sometime...If you called paint() or paintComponent(), I'm betting that you would see a stack overflow. The way I understand it, since you are calling repaint(), all you are doing is notifying the repaint manager that the component needs to be repainted at the next available time, not calling a paint method directly. good article on how painting is done : http://java.sun.com/products/jfc/tsc/articles/painting/index.html#mgr
2) If this is the case, and the two keep asking eachother to paint over and over, .....

Macbook Air running extremely slow - kernel_task at 300% cpu usage

I purchased my Macbook Air roughly 15 months ago and it's performance has constantly been impressive since I purchased it - until roughly a fortnight ago. I came home from work one afternoon and it was running at a snails pace. I had recently upgraded to Yosemite though I'm unsure if this had anything to do with it. I had also recently installed FitBit software to sync to my new FitBit flex.
It has continued to run in this manner constantly since the problem began. It is ridiculously slow, every single request takes a very long time to respond. Logging in takes forever. When I click on an app to open it, the icon bounces for 30 seconds or more, and it's not a smooth bounce either, it's quite a jagged bounce!
I'm hoping someone is able to provide some advice, guidance or help. The laptop is no longer covered by the 12 month Manufacturer Warranty, and I did not purchase an Apple Care plan as no Apple product I've owned before has experienced issues like this.
This whole experience is killing me! I'm suspecting hardware failure and I'm just so sad that this could happen to the laptop I've loved so much since I bought it!
The problem:
The kernel_task process is constantly running at 300% or higher cpu usage, with Activity Monitor indicating the processor is being maxed out by a system task. Also, the laptop's fan is constantly running at full capacity - from the moment the laptop turns on, or wakes up.
What I think the problem might be:
As a result of many, many Google searches, it appears that this behaviour may be due to the Macbook Air thinking it is overheating - and I will clarify here that it certainly is not. It is cool to touch, always, when this problem occurs. (yet the fan is almost taking off!). As a result of the MacBook Air thinking it's overheating, it not only is running the fan at a very high RPM (confirmed with iStat), but it also is intentionally choking the system with 'simple requests' in attempt to cool the computer down. Apparently this is a built-in feature of OS X. The kernel has priority over user tasks, causing all user tasks to be granted a lower priority, causing the computer to run INCREDIBLY SLOW. Even as I'm typing this, I'm about two sentences ahead of what is showing on the screen!
Steps I have taken:
- Read widely across the internet with every possible relevant search term I can think of
- Downloaded iStat to see if any of the temperatures are too high (they all seemed fine..)
- Disabled Bluetooth and Wifi. (no change)
- Reset SMC (multiple times.., no change)
- Reset PRAM (multiple times.., no change)
- Drained the battery completely (2 or 3 times, no change)
- Install Windows 7 on BootCamp in attempt to bypass the issue (CPU usage was 100% constantly in Windows also)
- Uninstalled FitBit software (no change..)
- Uninstalled other software I did not need (no change..)
- Attempt to boot into Safe Mode / Recovery Mode (even in this modes, the same thing is happening)
- Repaired Disk Permissions
- Backed up all personal data
- Used the built-in Internet Recovery mode to format my Macintosh HD and re-install a fresh copy of OS X (Mountain Lion). (no change…)
- Re-upgrade to Yosemite (no change..)
I've downloaded EtreCheck and here is the output:

Hi,
I have an update so I thought I would share in case any other users are experiencing a similar problem.
I made an appointment with the Genius Bar at the Apple Store.
I went in and they ran a thorough diagnostic check on my Macbook Air and determined that the sensors were indeed faulty - several were providing no information "No reading" instead of providing a temperature. Thus, the Air was unaware of the temperature across multiple components.
Despite the laptop being outside the 12 Month Manufacturer Warranty, the Apple Store determined that it was covered under warranty through Australian Consumer Law - the laptop is now in for a complete repair under warranty at no cost to myself.
I couldn't be happier.

Since 10.4.6 Update: "ATSServer" with high CPU-usage when opening PDFs

Since I've updated to 10.4.6 my system is very slow when I open PDFs (in "Preview" or "Acrobat").
This is caused by the process "ATSServer" which goes through every file in "~/Library/Fonts" (I have over 4.800 files there - but just a view are activated by "FontBook") and so it takes very high CPU-usage.
I didn't have this problem bevore the update and I didn't make any changes on my font settings.
I've cleaned the font cache, but it doesn't help.
Any ideas?

I haven't noticed any change myself, Dan, but I have the 2 GHz model.
One thing I HAVE noticed though after OS updates is that they can often result in a fair amount of file and free space fragmentation immediately after installation. OSX's routines will deal with fragmentation of small files , but not of large ones (over 20 Meg), and it won't deal very effectively with free space fragmentation. If your HD is getting full this can cause significant slowdowns, especially where video is involved.
You should also run DiskUtility and check for any directory and permissions issues.

High CPU & Memory issues - Excessive and unnecessary CPU usage in Firefox for Windows (see also questions1003966 & 998289)

I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.
I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?
I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.
There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.
Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.
The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.
Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.
The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).
I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.
This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.
Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.
I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.
I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.
The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.

I share jmward's frustration. This is not a bug report so much as a request for a badly needed feature, ie the ability to have Firefox be able to tell us which tabs on which windows are eating time so we can target them. There are some very poorly written web pages out there which just plain loop while making no updates or inconsequential updates on the page.
This is not a OS problem; jmward runs Windows and I run Linux but we have the same issue. It is not a question of Firefox plugins or extensions, or even viruses; I have a new, clean Linux install but have the same problem on both my regular Firefox AND on a FRESH install of the latest Firefox (35.0.1) which has *NO* non-default plugins or extensions.
Here is an example of a web page which will eat 100% of one CPU's time:
http://patch.com/massachusetts/arlington/arlington-woman-allegedly-attacks-neighbor-snow-blower-0
I will attach 3 images to back up my claim. All of the images show my dark blue system monitor (gkrellm) superimposed on the web page. The top graph shows CPU time. I have 4 CPUs in my machine, so 25% means the web page is eating 100% of one CPU equivalent.
The first image shows the load of the offending page with elevated CPU usage along with the download net activity on eth0, but the CPU activity does not stop when the download activity is over.
The second images show the steady state 100% CPU equivalent of this page just sitting there apparently doing nothing. It IS, however, doing at least two different things. I know from my regular Firefox where I have "Remove It Permanently" installed that if I remove the the little weather indicator in the upper right of the offending page that CPU utilization drops to about 40% of one CPU equivalent. If I use RIP to remove everything else right down to a bare screen that 40% utilization stays until I delete the tab.
The third image shows the CPU utilization drop to zero when I delete the tab holding the offending page.
Now I will add a note here: If the offending page is NOT the top tab in a window then it stops eating time. The offender will also stop eating time if I minimize the window. However if I have another window up but leave the offender up on top in its window it continues to eat time even tho I am looking at another window. The offender will continue to eat time even if its window is completely covered by another window, and it will also eat time if I switch to another desktop.
I will often have half a dozen windows open, and there are many pages out there which will suck endless CPU time. Unless I want to open up a new tab on each window before I leave it there is likely to be some tab on top eating time uselessly. Get a couple of those going and Firefox becomes sluggish and can even stop responding for many seconds.
I guess I not only want to have Firefox tell us which tabs are eating time, but I would also like it if Firefox would stop giving CPU time to any tab which is not visible because it is covered by some other window and/or it is on a desktop which is currently not showing. If you can stop a tab's CPU usage by reason of tab-not-showing then you should also be able to stop its CPU usage when the window is covered or on the not-top desktop. Indeed is there any reason to not schedule absolute CPU utilization priority to the visible tab on the window with focus and give time to the other tabs only when the visible tab isn't using time?
My final thought on this is that I have had Firefox SO tied up sometimes that I swear their are web pages which are eating time even tho they are not the top tab. I regret that I do not have an example to show you. But Firefox grinds to a complete halt on a regular basis, and that is not acceptable. I am a programmer with long experience in multi-threaded programs so I *know* there is no reason you cannot do better. If there were another browser around which had the commitment to privacy which Firefox has I would probably switch out of shear annoyance. :-(
