Satellite C650D - CPU usage is jumping around

I bought a Toshiba Satellite C650D 2 months ago, and I used the Windows 7 that came with it thinking it was all fine and dandy until some days ago, it started getting random lag spikes.
At first it just occured when watching movies (tried 4 different programs, reinstalled all driver, scanned for malware, defragged, you name it) then it started happening outside the movie-viewing aswell. That did it for me, and I installed Windows XP. I've done so 3 times now, clean installs of Windows XP. At first it seemed fine. For some hours, then it started lagging really bad, not like in Windows 7, but CPU usage is jumping around in the boundaries between 1% and 99% randomly, but there is no processes taking it!
It lags whatever I do, just opening notepad can make it jump. I figured it would work with a clean format, but noo, of course the problem reoccured. It could perhaps be drivers, seing as the problems in Windows 7 and XP are somewhat different. I'm at my wits ends here on what to do, anything would be helpful.

Satellite A45 - CPU usage is high and applications slow

Hi all,
I'm trying to debug a hardware problem on my Toshiba Satellite A45. I'm running Ubuntu 10.04, but I don't believe this is OS or software related.
THE PROBLEM: CPU usage is high and applications slow to a crawl after using a memory intensive application for a few minutes, i.e. viewing a video or playing a game. Basically, anything that might use the screen a lot. If instead I work only from a command prompt, even when the application might be doing a lot of work, I don't encounter this problem. After shutting down all application, CPU usage is still higher than normal (90% idle, should normally be about 99% idle).
Xorg typically now showing about 6% usage (normally < 2%). If I at any time after this try to work in any application, usage is still bogged down. Only a reset gets me back to normal.
Note: My system had always worked fine, and I had not done any software installation or changes when this started happening.
However, the laptop did go through an 800 mile round trip in the back of the car in a padded laptop bag.
DEBUG: This doesn't seem to be RAM as I have replaced RAM and reseated the RAM, and the problem still occurs. This doesn't seem to be the Hard Drive as I can try to run from a Live CD (no HDD usage) and everything still slows to a crawl.
HELP: I'm not sure how to debug from here.
I don't have extra bits of hardware to do swaps.
Any ideas how to further debug this?
Thanks,
Grommit

Hi grommit
What do You think about the possibility that your PC is becoming overheated?
To me this sounds like such a scenario.
Your using an application which is intensive - which makes the unit warm up a lot probably.
After that everything is sluggish. This is what may happen when cooling is not sufficient - the CPU is throttled to reduce heat generation. And the effect is that the unit works pretty slow.
May I suggest that You try to let the unit be off for some time before trying it again - I don't know your possibilities, but I would put it on the balcony or on the floor below an open window too cool it really much.
Then try again from whatever media you like.
The result? Good performance for a while again? Then either clean the cooling module yourself or have a repair workshop do this for You.
Good luck and stay with Linux! :)

Satellite A200 crashing when moved or when CPU usage is too high

Alright so fairly recently my Toshiba Satellite A200 has started crashing whenever I pick up the laptop or run any processes that take the CPU usage up to around 100%.
This essentially means no 3D rendering or games and no running Photoshop and iTunes at the same time etc. Here's the kicker though, it only happens when the laptop is plugged in and not when on battery power alone. I've already tried using a different AC adapter and I cleaned off the hard drive for a fresh install of Windows 7 neither of which fixed the issue. I even went so far as to update the BIOS.
I am not fairly determined that this is solely a hardware issue but I was wondering if anybody had any suggestions as to which part may be acting up on me. Like I said it still works like a dream when running on battery power.

hi Cyborg771,
it seems to be related to the ac-in jack..
is there any change or symptom when moving the ac-plug?
also the circuit that is managing the power supply could be the "bad guy"
if the contact to the powerboard isnt good, the circuit starts to check the state every 10ms..this will slow down your machine...
how old is your notebook?
still got warranty on?
a solution may be to solder/fix/change the jack
or see a servicepartner

Cpu usage at 100%

I am running LabView 7.1 with DSC loaded. My project controls two reaction vessels through compact fieldpoint I/O modules. There are PID loops, data logging, trending and general value displays. The I/O is a mixture of analog and discrete. With trending enabled, my CPU usage jumps to 100%. This happens immediately, not slowly building over time. When this happens, the other portions of the program suffer, i.e. slower updates to PIDs and subsequently out-of-control loops, along with extremely slow updates to the screens. Disabling the trending results in the cpu usage dropping to around 3% and normal PID control and screen updates. The computer is plenty fast with enough RAM. Trending is vital to the technicians ability to manage the reaction. Has anyone seen this issue? I am using the read traces vi to populate the trends.

Sorry, I cannot test because of missing subVIs, but I would NOT place waits inside these FOR loops! They run for a limited number if iterations and do nothing special except some property nodes. Since your code is heavily sequentialized (sic ) all you do with these waits is prevent the program from doing anything useful.
What might help would be do defer panel updates during the sequence of FOR loops containing property nodes. (see e.g. http://forums.ni.com/ni/board/message?board.id=170&message.id=164135#M164135)
You have a lot of duplicate code that could be consolidated. Overall, the code is very hard to navigate because of the deep stacks of sequence structures.

Database file + high cpu usage

this has only started happening since i formatted and reinstalled windows. i have tried using both itunes 6.0.2.23 and 6.0.4.2 and both have the same problem.
my music library contains 5088 songs, i have tried deleting heaps down to around 3400 and problem is still there (ie i have eliminated number of songs as a factor cause before formatting i had more than 3400 but less than 5088)
when i play a song in itunes after about 5 seconds my cpu usage will jump to 100% this is on the "system" process, itunes itself uses around 2-5%. i was watching the itunes music folder though, and what it is doing is creating a new temp file (of 7.27mb) then renaming it to replace the current "itunes music library.xml" file. as soon as the xml file is replaced (takes about 10 seconds) cpu usage returns to normal.
this exact same thing happens when i quit itunes, although it takes roughly 20 seconds.
i have tried deleting all files in the itunes music folder apart from the base database file, that did nothing.
i tried removing the entire folder and letting it create a new blank library, then added just 1 album, and it worked perfectly. i also noticed that on my original library most but not all AAC encoded files did not cause the cpu spike, all mp3s did.
i tried creating an entire blank library and adding all my music back in, it still did high cpu usage so i would assume my current database is not corrupted.
does anyone know a solution to this? how to stop it recreating the xml file with every song played. the only thing important to me is saving my playcounts, so any solution which does not require losing them would be appreciated.
also yes i have tried completely uninstalling itunes, for both of the versions mentioned above, also tried updating over the top of the current installation, problem occurs everytime.
i am running service pack 2, all current windows updates installed, no spyware, no viruses.
thanks.
Windows XP Pro Athlon 64 3000+, 1GB DDR Ram

It may be iTunes, but it probably is not. iTunes is just affected by a conflict with another program (possibly).
Do you have a spy sweeper/virus scanner/etc. that periodically scans your PC memory? If so, then that is what may be interacting with iTunes.
You should list the iTunes Folders as part of the exclusions within your Virus Scanners, and other Security software.
BTW: I have a Library with over 13,000 song references. I do not see the same CPU spikes when playing music. It's not the size of the database - not at your current level.

Why is Flash CPU usage so high on my PC?

To other psoters here - Please do not hijack my thread for any other performance issues with Flash other than high CPU usage.
This thread is (hopefully) dedicated to why the CPU usage on my desktop PC jumps when I go to a page with flash 'content'. Thank you!
I am hoping that there is an answer for why my computer is using a very high amount of CPU percentage when I am viewing flash content?
I am running Windows Vista Home Premium Service Pack 2 on a Gateway GT5432 desktop computer.
I have Shockwave Flash version 11.7.700.169 installed.
I am using Firefox version 20.0.1 (but I have seen same problem of high CPU with Google chrome).
Here is one page that is causing the high CPU usage.
-   http://logansroadhouse.com/Default.aspx
That page appears to have lots of Flash content.
If I open that logans roadhouse page, my CPU usage goes from an average of 12%, to 80%!
The process I see jump are:
- Firefox's "plugin-container.exe" goes from 0% to about 50%
- Firefox browser "firefox.exe" goes from around 8% to 14%
- Adobe's plugin "FlashPlayerPlugin_11_7_700_169.exe" goes from 0% to 16%
- TOTAL CPU change from 8% to 80% after opening up just this one page !
When I close the page, the CPU usage goes down again. Open again - CPU goes high again.
Also if I go to the firefox addons page and DISABLE the SHOCKWAVE FLASH plugin, then go to that Logans Roadhouse page, very little of the content I saw with Flash enabled is visible - which I take to mean it is a page consisting of lots of Flash 'content'. Also the CPU usage remains low (8%) if I go to that page - after disabling the Shockwave Flash plugin.
I have seen the CPU also go high on youtube.com pages also - CPU jumps just as I said above - if Flash is enabled. CPU then drops after disabling Flash plugin.
I was hoping you had a fix for my problem? My PC becomes almost unusable with the CPU so high. It sure looks like it is the Flash plugin driving the CPU so high.

I am also facing the same problem from last 2-3 weeks since i upgraded my flash player to latest one.
All softwares and drivers are upto-date.
I play wartune MMO flash browser based game (also applicable to youtube videos) which is now using above 80% of CPU. Before upgrading, CPU usage was normal around 5-15% depending upon the events, but not more than 20% even if i open 3-4 accounts of wartune in different windows at the same time. It happens in all browsers (IE10, Mozila22.00, Opera12.15, Chrome27.0.1453.116 m).
I tried all solutions like disabling hardware acceleration, flash cache size to unlimited, clearing all flash cache etc but the same problem.
Please fix this problem as soon as possible.

High cpu usage when using flash player

Hi,
Just updated to Mavericks and now I'm having very high cpu usage while watching streams using flash player. CPU usage is somewhere around 110% and after a moment the stream starts to lag and fps is slowing down. I also tried using Chrome but with no difference. Flash player is the newest version 11.9.900.117.
Any ideas on how to fix this?

i think its the best to hit the report a problem button in safari, since its appears since i updated safari to 5.1.4! maybe they make a additional update

CPU Usage - Generating Word Docs from RoboHelp X5

If you have generated a fair-sized document through RoboHelp,
and you are having problems with your CPU usage pegging out around
100%, bouncing up and down between 50% and 100%, the page
repainting as you scroll through the document, etc., this solution
is for you!
I am using RoboHelp X5 to generate large Word documents
(2003). This solution worked perfect for me. The problem is with
document corruption, apparently. After you have generated your Word
document and opened the document, be sure to display the paragraph
marks. You will probably see the “]” mark at or near
the end of the document. Select your entire document,
except for the final paragraph mark, making sure to exclude
this symbol, and copy everything else. Open a blank Word document
and paste this content into the new document.
You will now need to reattach your template (.dot) file for
the generated document through Tools/Templates and Addins:
1. Locate the applicable document template and attach it
(it's typically in the base generated project directory in RoboHelp
- .dot file). Click the OK button to save.
2. Return to Tools/Templates and Addins. Click the Organizer
button to display the Styles tab.
3. In the right-hand list (In Normal.dot), Close the
Normal.dot file
4. Open the same RoboHelp .dot template as you selected
previously.
4. Select all of the styles once they display in the right
pane and click the <<Copy button to copy them all over to the
document template. Confirm that you want to replace all styles in
the document.
5. Close the menu using the Close button. The dialog closes
and your styles should all be updated, if your styles were set up
appropriately via template and style sheet settings.
You may need to also adjust the Page Setup page width
settings, if necessary.
Good luck!

Peter:
Thank you for responding to me, as I may not have been clear
enough, and I apologize for that. I was trying to keep it short and
sweet. This problem started when I began using RoboHelp X5 this
year.
To clarify...
- I'm not concerned with CPU usage during document
generation, that is to be expected. The document will need to be
generated originally from a RoboHelp WebHelp project. This does not
change. The problem takes place AFTER you generate a large document
and then open it in MS Word.
- My documents are large, 140-500 pages. It took forever to
scroll through the Word document (RoboHelp-generated), the screen
kept repainting, and the CPU usage stuck fluctuating frequently
between 50% and 100%, not allowing me to do much else. Editing
those documents was a nightmare. Even if I shut down all other
programs.
- Something translates to the Word doc from RoboHelp that
maxes out the CPU usage, and I can't locate the exact culprit.
However, it appears to be tied to the faded "]" symbol at the end
of the document (there is a "[" at the beginning, too). So you have
to omit more than the last paragraph mark; that symbol also needs
to be left out.
- The "corruption" information came from Microsoft; it could
be something other than that, but this is what they said. I found
nothing that would help on the RoboHelp forum, so I went to
Microsoft to see if they had a solution. Apparently, this is a
common problem with Word 2003, but the articles didn't mention
RoboHelp in the issues. I tried this solution, adding the omission
of the "[" symbol, with complete success.
- When you copy the document without the last paragraph mark,
it will still include the headers/footers when you paste it
(although you may need to adjust them slightly). This is not the
problem.
- When a document is generated, you can select to use a MS
Word template, which I do. I fully use the style sheets in
RoboHelp, and they match my Word styles (template) to keep things
in sync. Actually, this Word template remains in the project; it is
not moved to the folder that holds your Normal.dot file. So the
link to the template in RoboHelp from your document does in fact
remain intact. However, you can copy that template to another
folder outside the project and link it from there, but it won't
matter.
- The Word template (.dot) needs to be reapplied in order to
restore your styles, as the Normal.dot styles are applied when you
copy the content over to a new document. It doesn't matter where
you store the template. I reapply this SAME template after I copy
and paste the content into the new document. This is not the cause
of the problem. Note: The application of a template is not the same
thing as going back to the master copy. This is still a fresh
document, with the content pasted in and the same template applied.
- I have tried deleting the local copy and starting over. I
have moved the file to another location. I have renamed or created
a 'save-as' copy of the file. I tried editing out any extra
un-necessary merge-tags in Word, looked for macros, etc. All of
these things do not resolve the CPU Usage problem.
I hope this makes more sense. You can try it out if you wish,
but you will need to do this with a large document and use the
Print View when looking at the document in Word. You'll have less
of a problem in Normal View, or with a smaller document (under 50
pages).
Good luck!

High CPU Usage CS4 in Snow Leopard

Hi,
I have some weird problems going on with Photoshop CS4 on my iMac.
I have an iMac dual core, with 4GB of ram.
Never had any problems regarding the CPU usage.
The last couple of days I have an high CPU usage when I open an picture.
The CPU usage will rise around 150%
I have had an clean install of SL but this didnt fixed the problem.
Anyone that can help me?
greetz and thanks danny

Why is this a problem?
Like high RAM usage you should be glad that your resources are being used instead of sitting there idle.

Oracle 10g --- cpu usage

Hi,
i just installed oracle 10g on my laptop and it uses too much resources. cpu usage is always around 96-100%. whats the reason that it starts by itself and is taking too much resources.
Raj

The reason it starts up automatically is because the service (OracleService<name>) is set by default to auto start. You can change this to manual if you don't want the database to startup every time you reboot your laptop.
As far as CPU usage...Do you have a real-time virus scanner installed? Those things will kill a laptop. I'd rather have the virus (not really).
I have 10g on my Windows XP desktop and the CPU usage is normally at 0%. It takes up a lot of memory, but if it's mostly idle, it doesn't consume much CPU resources.

100% CPU Usage caused by HMI

Hi everybody:
I'm working with LabVIEW DSC 8.2.1 in a system that monitors many variables of a plant, such a typical SCADA system. For this reason, the use of the graphic tools is highly used on the development of this system. Everything works fine, but I have only one problem.... the usage of the CPU.
When I am working on the development system I (not the executable) I start the application and after the variables are initialized and every process has started and are running , the CPU usage is raised around 90 - 100%. After a few days investigating the reason of this, I realized thay when I change the view on the screen to another view, for example the block diagram of the application, while the application is still running, the CPU usage goes around 15 - 25%. I've tried these many times changing the view from Front panel to Block Diagram and viceversa and the result is always the same: Front Panel= around 100%; Block diagram or another view (other applications MMIs, or Block Diagrams, etc.)= around 20%.
Another thing that I realized is that the other view (different to front panel) has to fill the entire screen to work the way I'm telling before.
When I build and run the executable, the usage of the CPU is the same... (around 100%), but I can't see any other application, because the application built is the shell of the OS, so no other views are available.
I don't know if there's some other consideration to take into account about the HMI when creating an application, and I'll appreciate very much your help.
Thanks in advance!

100 Percent CPU Usage when you run programs after you install Windows XP Service Pack 2
CPU Usage 100% Symptoms
When you run some programs, the CPU Usage meter in Task Manager may indicate CPU Usage 100%. When CPU utilization reaches 100 percent, programs will run very slowly or stop responding (hang) and your computer is freezing or crashing.
Noteress CTRL+ALT+DEL to view CPU utilization, click Task Manager, and then click the Performance tab.
These symptoms occur after you install Microsoft Windows XP Service Pack 2 (SP2).
CPU Usage 100% Cause
These problem occurs because of the user interface code that is included in Windows XP SP2. The high CPU utilization is caused by the additional overhead that occurs when the IsWindow function is called by the user interface code.

Flash player in Chrome high CPU usage

Laptop Specs:
Windows 7 64-bit
Lenovo Thinkpad T410
Intel Core i5 CPU m 520 @2.4 GHz
8.00 GB RAM
This started happening a couple months back (September ish). My laptop run perfectly fine with game play, watching HD movies, running photoshop, etc. It's only when I start up Google Chrome that the CPU usage would spike. It remains under 80% though. With normal internet surfing my CPU usage will teader around 30-40%. When I watch videos via chrome, that's when I have problems. For example, when I watch a "Walking Dead" episode from AMC.com, my CPU usage will spike to 90-100%. After a minute or two my computer will do a hard shut down, as if I pulled the battery out. I'm guessing it is because my CPU is being overworked and over heated. I thought this problem was only with Chrome but when I pulled up the video with internet explorer the same thing happened. I've cleaned my CPU & fan and bought a laptop cooling fan, no help. I've disabled the multiple flash plugins on chrome, no help. I've updated chrome and flash, no help. What should I do? I've read online that this is a common issue. Has there been a solution yet?

Same problem here:
     - x86 Family 15 Model 6 Stepping 5 GenuineIntel ~3000 Mhz.
     - Intel 82945G Express Chipset Family/128MB
     - 4gb RAM
     - Windows XP
The problem is obvious on pages with Flash ads, YouTube (auto resolution), etc. I have the same problem with IE 8; I am guessing, it is not related to the browser.
Ordinary pages with Flash ads keep the CPU at 15%, at least, when not visible; when visible it oscillates from 15% to 90%.
In YouTube the CPU goes to 80% when the video is visible and decreases to 20% when not visible, but it spikes to 30%.
My other, I7, computer has no problem.
Adobe, I hope you will come with a solution. An algorithm should not rely on computer's power.

I have very high 100% CPU usage when I run itunes.

Normally I don't have any problems, but now when I start iTunes it eats up my CPUs. Any thoughts?

I am having this same problem. When running iTunes on my macbook pro, i notice my CPU usage is hovering around 94-97% constantly. Has anyone found out why?

CPU Usage Seems Very High

Seems my CPU usage is very high.
Right now I've shut down any other users and am only running firefox, activity monitor and some dashboard widgets (that the activity monitor shows are not using any resources) yet my CPU usage is bouncing around with user at about 70%, system at about 15% and Nice about 10%
On the activity monitor something call perl seems to be using all the CPU.
What's going on and what can / should I do?
Thanks

I'm not making much progress.
This morning after startup and with both my wife and me logged in the HP Scanjet manager process seemed to be taking over -- I quit the process and the CPU use calmed down.
Then I rebooted and with only me as the user and only the activity monitor launched the "perl" application consumed around 90% of the CPU.
I unplugged all extra USB stuff (including the scanner) and rebooted and the same is happening -- perl is at about 80% but it seems to split responsiblity between the user and the system (40% user / 60% system with perl at 80%)
The only other thing I have plugged in is an external hard drive connected by firewire -- it takes a back up every morning and houses my iTunes library.
Any thoughts?

High CPU usage on X

I use KDE 4.5 and a NVidia card (8400M G) with the official driver.
Sometimes I get high CPU usage on X (around 50% usage) when using the computer, particularly when viewing PDF with Okular making the scroll a bit sluggish. Is this normal behaviour?
My system is up to date.

Try viewing that pdf outside KDE, try the nouveau drivers - this way you can (hopefully) nail down what the problem is. Cairo, poppler, pango - are you using the stock packages or some AUR/modified ones?
