• Satellite A40-231 - 100% CPU usage when any browser works

  Hello
  my laptop is satellite A40-231, I have a problem for days.

  When I open any browser (I tried firefox, IE and chrome) I can't watch the video, everything is slowing down, I can't navigate between pages.

  I took a quick glance to the use of the cpu and it increase to 100%, it never decreases. When I close the browser, the CPU usage drops to 15%, which is normal. I thought it might be a virus that internet connection and make things slower. That's why I format my laptop. I deleted all of my hard drive and reformatted. I installed Windows again, but he has not changed. I even installed ubuntu (I thought maybe virus can not work under ubuntu), but it's the same thing. I turn on my laptop and I open a browser and the laptop slows. I have clean the cpu fan it has not helped.

  I tried to solve it for days I could not sleep properly, I'm about to cry :(

  Please help me please.

  Hello

  You have reinstalled Windows using the Toshiba Recovery disk? This drive will restore the settings from the factory with all the drivers and tools so everything should work fine after that.

  In addition this happens with LAN or WLAN connection? You should try it with the other connection.
  Also check your router and update the firmware. Try to disable the encryption, MAC address filtering, etc.

• The CPU usage of Flex-2 15 30% when idle after upgrade to Windows 10 * contains large Images *.

  BTW my 15 Flex-2 upgrade to Windows 10 Home took place, working after a few minor updates manual driver (WLAN, graphics)...

  However, since the upgrade, I feel an annoying symptom, which has been reported by users of other brands as well.

  Although I already follow most of related advice (known assassination unnessary process, change of reports), the CPU usage is still constantly around 30%, causing the fan to operate continuously and even more unsatisfactory: extremely affecting the battery life! Using processexplorer that I discovered, that svchost (or one of its processes) is at the origin of the problem, not one of the applications. As I am not able to dig deeper, I wonder what measures taken so far by Lenovo to have the Microsoft fix this problem.

  Attached: screenshots 'notification', 'Treaty', 'system '.

  Other tips are appreciated.

  

  

  

  Mod edit: added warning about large images for those who have slow Internet service.

  UPDATE Oct10:
  

  Went to manually check tile Lenovo Support and offered an update of SystemInterfaceFoundation.exe.

  Run the update and believe it or not: the CPU usage is almost back to normal (about 4%) with browser open FF and AV SW race. less than 2.5% use svchost. Fan turns down to 'stop' or low speed.
  Can someone pls? Be wary of situation for the next few days...

  Hello

  Glad to know that the CPU works normally now. Thank you for the accommodation that we know. If you have any questions on Windows then post in this forum.

• When I used to hit ctrl, ALT, delete, Task Manager appears. Now, just the screen CPU usage. How can I get that back for the bigger task manager, which, the CPU usage was a tab to the breast? Thank you.

  The Task Manager is now just 'CPU' because I must have hit something wrong.  I was hoping just to click on the tab use the CPU in the Task Manager, now somehow when I hit CTRL, remove alt. it shows only the CPU usage graph.

  Double-click the window border.

• The CPU usage goes up to 50-60% right when I start the computer.

  Original title: high CPU usage

  I have a pc with windows 7 64-bit, 4 GB ram, AMD Phenom II x 2 511 processor and a Nvidia Geforce Gtx 260. The CPU usage goes up to 50-60% right when I start the computer. I ran the Task Manager and there is no program using the cpu. It has nothing to do with anny viruses because I scanned the computer with two different programs. We do not have Steam and the EA download manager. What could be the problem?

  "Idle" means "doing nothing."  Windows runs the "System Idle" process when the processor has no useful to perform tasks.

  Look at the status bar at the bottom of the Task Manager and you will see that the CPU usage does NOT include the percentage for the System Idle process.

  What are the processes other than Idle System added up to 50-60%?

  I suggest that you run an online scan using antivirus ESET online--> http://www.eset.com/us/online-scanner/

• High CPU usage when more than 30 sessions disconnection/connection

  Hi guys,.
  I had this problem for a long time.
  Environment: RAC 10.2.0.5. Oracle enterprise linux 4.8. Application Java B2C with dbcp and oc4j dirver.
  
  Server type: Dell R815. 48 processors 128 G MEM for each node.
  
  This is a lot of the web application connects to the database and when one of them is down it will restart soon and try to connect to the database again. Each of them will try to get 50 connections simultaneously initially.
  
  So when it happens, the sys cpu usage % will pass to more than 70, 80, 90 percent each time.
  
  BTW, it also happens in more than 30 logout simultaneously.
  
  Could someone tell me what the problem is?
  
  
  Thank you very much.

  The task of creating a connection and the session must be serialized, and if you start a number of connection or disconnection is trying at the same time you can end up with a storm of activity on the relevant latches that effects serious knockon. I'm a little surprised that you see that with only 30 to 50 connections, but maybe you have a couple of processors.

  I made some comments to this topic on another thread a while ago: Re: generals to have a high value of the init process (or sessions) parameter

  It is possible that you can configure the application server in order to limit the speed at which he tries to create or cancel the connection - for example, there may be configuration settings to say things like: 'create no more than 5 both', 'just wait a second between disconnections. (Oracle introduced parameters to logoff storms - but maybe they don't work in your version).

• Svchost.exe causing 100% cpu usage during the update of windows, even when disconnected.

  I recently had to re - install windows xp on a new hard drive for replacement. My version of xp home edition, SP2 OEM installation disc. (This is ith group included IE6)

  Once installed and running, could access windows update.

  Read all the threads associated etc. and installed SP3, disc after downloading microsoft on another pc. Installed after three trys, first two caused various mistakes, but third attempt seems OK!

  I've also updated the IE6 to IE8, as some sites obviously did not work properly with the older browser.

  Now go do the automatic updates, or log for manual updates... BUT!

  During the process, my cpu fan comes on fast and permanently! The CPU usage is showing that 100%, pc slows to crawl, the mouse becomes slow etc.

  This has never happened before on this machine before you reinstall clean, he had already automatically updated to SP3 and went very well, it was some time ago, before the failure of hard drive, and it has never had this problem!

  Only since having to do a cleaning manual update and re - install.

  The culprit seems to be svchost.exe, once it is used by the update, running the cpu at 100% and continues to do so EVEN after stopping the service, until I manually stop with the Task Manager!

  The svchost.exe instance showing a high is use: SYSTEM.

  According to the files of help here, it is a known issue and a fix KB927891 was issued for SP2, but this should NOT be necessary for SP3, and in fact difficulty used to perform anyway under SP3!

  Ideas for a guy to fix?

  I appreciate the support for XP runs out quickly, and after this update of windows will be redundant, but in the meantime it is always useful!

  Also if I turn off the automatic updates, how can I stop this annoying popup warning bubble?... I can't live without updating, but this bubble nag drives you nuts! :)

  OK just a update, now running cool and 100% auto update and manual update... How? I hear you ask...

  Well I had a beer and a reflection and came to the conclusion, it must be 'order' in which I updated the clean installation of XP.

  Origin, I loaded the old OEM disc new hard disk, loaded the drivers etc, then stop at windows update for updated files.

  Who told me my old incompatible browser and suggested an upgrade.

  I downloaded and installed IE8... still no joy, reading the forums comments I downloaded and installed SP3... which SEEMED to work, BUT then all the hassle of cpu to 100% with the automatic update and updated manual on the windows don't update site!

  So I just gritted my teeth, formatted the drive, another OEM of XP Home Edition SP2 installation loaded the drivers, installed a copy saved to SP3 and after restarting, THEN installed a saved copy of IE8 and THEN trotted off the coast to the windows update site... low and behold, it the connection without problem, did a search, and required updates appeared on the screen without delay all 123 of them...! :)

  Did the updates, restarted and everything was fine, updates automatic in market and left the machine, after about 30 minutes appears the yellow shield, and it downloads a couple more update files without problem.

  All this time I followed the via the Task Manager CPU usage and the strange spike waited 100% apartment, it was on average from 5 to 20%!...so a great improvement has this effect, by simply changing the order of the updates installed from the original! SP3 IE before IE8.

  May not work for all have to do a clean install because of the HD failed, but its worked for me, and I am once more a "happy bunny!

  Dave was soon.

• Constantly higher than 50% even when idle CPU usage. NT kernel & system?

  Hi, I wonder if anyone can help? I built my own computer and after I installed Windows 7 and only the drivers for the respective hardware, my CPU usage is consistently above 50% and jumped off from top down to anywhere between 50 to 100%?

  I have a motherboard Biostar GF82000E with an AMD Athlon II Quad processor and also a Nvidia 9400 GT graphics card. For which I have all drivers up to date.

  I tried to install Windows 7 completely fresh with nothing installed, I ran Task Manager, immediately, and you can see from the picture what I mean...

• FIFO DMA read high CPU usage

  Hi al, it's a long!

  I noticed a strange behaviour when I read from a FIFO DMA between FPGA and RT host on my crio (9014 controller and 9104 bottom of basket). The FPGA is writing data to the FIFO 2 points every millisecond and the loop of the RT is the reading of 500 data points each loop of the MS 250 CR period is controlled using the hold until the next ms multiple function.

  Wait until the next use means ms that during the first round, the wait will be not so I gave the FIFO DMA read method a timeout of 750ms to allow data points to accumulate on this first iteration.

  I then ran the VI and it read the data as planned and it was always 0 in the FIFO. Then using the system monitor, I noticed the CPU usage on the RIO and was surprised to see that it was 30% !

  After a lot of puzzle and many other attempts as to set the timeout to zero if delays fair read until here, I've decided are enough data points and then executes a little behind so that there is always a constant number (non-zero) of data points in the FIFO. Now, the VI runs and only use about 3% CPU.

  I thought that in the first case as I read exactly the number of points in the FIFO that I was tripping some kind of voting behavior in the playback feature which has been hogging the cpu.

  So I ran a business with a zero time-out, where I was reading with 0 points of data to the left in the FIFO as in the first case and waited to see if the delay of read but it never does and the CPU usage is normal.

  So what's happening? I'm puzzled!

  Thank you

  Steve.

  Hi Steve,.

  I think I can explain the use processor behavior that you are experiencing:

  Case 1: Loop with nonzero time-out

  -Your code starts with wait a multiple ms: This means that a 0-250 ms timeout occurs (on average 125 ms)

  -Then your code tries to read 500 data points in the DMA FIFO (if 500 points come in every 250 ms). All data cannot be presented yet.

  -If 500 points are not yet ready, polling occurs until they are. During the time of the poll, the CPU usage is high. Finally, the data is read.

  -The next iteration of the loop begins.

  -The code is now expected up to 250 ms after the last function call until the next ms Multiple. Roughly the same amount of data should be available by the end of this expectation as in the last iteration. Therefore, the question about the next FIFO DMA read should be roughly the same, and the CPU usage will remain high.

  Case 2: Loop with zero time-out

  -In your code, immediately after the first call to wait until the next multiple ms, you "synchronize" by reading all the remaining data from the FIFO.

  -In the next iteration of the loop, we can expect the call until the next ms Multiple wait the entire 250 m means that the data DMA FIFO (discount jitter) should be ready. If jitter is low enough, this will result in delays very little of the read DMA FIFO and a low CPU usage.

  I would recommend either using a timed loop and read the exact number of data points available (if your application can handle variable size data sets), or using a while loop as you are and make sure that the loop priorities are defined such that the CPU usage high does not affect critical functionality.

  Thank you for the very good question; I personally really like thinking through these issues! Please let me know if you have any questions that deserve further discussion and have a nice day!

  Kind regards

• Satellite R830-1GZ - CPU usage high (> 25%) and increase in the speed of the fan after reactivation

  Hi all

  The CPU usage of my laptop shoots upward to 25% (and beyond) and increases in fan speed considerably after waking up, but only when I use an external mouse (Microsoft Natural Wireless Laser Mouse 6000) - disconnect the mouse once it happened does not solve the problem, so I always have to restart my computer if I let go sleep with the connected mouse.

  I noticed that when this produces the system interrupts - delayed appeals procedure and Interrupt Service routine appears in the resource monitor > CPU > process and seems to explain the increase in the use of the processor.

  Any ideas on how to solve this problem would be most appreciated.

  I use a Toshiba Satellite R830 1GZ with Windows 7 (64-bit). This problem will not occur when I use the same mouse with another laptop (Dell with Windows XP).

  Thank you very much.

  I think that the process that controls the mouse MS WLan does not close properly.
  The system to memorize it and therefore the cooling module begins to spin faster because these processes stressed the central unit.

  Maybe its caused by the mouse driver
  Have you checked if there is an update to the driver?

• Fort Portege M800 - always at 50% CPU usage or more

  Hello

  my laptop M800 is still running with the fan at full speed, the CPU usage is running between 50% to 100% even when no programs are running, this normal?, seems the computer seems never to go to a mode of rest or inactivity.

  I hope someone can help

  see you soon

  Hello

  Do you use your Portege with factory settings?

  What you need to do is to stop all unnecessary processes running in the background. This will reduce the CPU usage.
  By the way: change the parameters of cooling method.
  You can find it in the plan advanced power settings > Toshiba Power saver > cooling method. Change it to optimized battery.
  It will reduce the cooling fan activity and cell phone will last a lot quieter.

  Test it please and post comments.

• Satellite C650D - the 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 that it was fine and dandy until a few days ago, he started having random lag spikes.

  At first he just happen when you watch movies (tried 4 different programs, all reinstalled the driver, scanned for malware, defragmented, you name) and then she started to occur outside the viewing of film aswell. Who did it for me, and I installed Windows XP. I did 3 times now, clean install it Windows XP. Initially, it seemed fine. For a few hours, and then it started lagging really bad, not like in Windows 7, but the CPU usage is jumping all over the boundaries between 1% and 99% at random, but there is no process to take it!

  He lags behind what I do, just open the Notepad can blow. I thought that it would work with a format clean, but no, of course the problem reoccured. It might be drivers, see problems in Windows 7 and XP are somewhat different. I'm in my intelligence ends here on what to do, whatever that is would be helpful.

  Hey Buddy,

  Looks like on your laptop is a background passes process that is causing this different and high CPU usage.

  What happens if you install Windows 7 Toshiba Recovery disk and look in the Manager of tasks? Directly after this installation, you should have a low CPU usage and stable because it s installation of Windows from Toshiba.
