• HP mini5102 interruption using high CPU after sleep / resume

  I have the same problem described recently (without solution) on the Forum of Support HP Business. After resume from sleep, 5102 HPmini consumes constantly about 30% of the capacity of the CPU even with the system at idle. Sunny (0-3% CPU use at idle) before going to sleep. As Roderick Laird (copied below) I've already got rid of wireless assistant that caused a different problem of high CPU usage (100% CPU use even before you sleep / resume, now fixed by an update of the version unless served for those who want to keep the wireless assistant).

  Consumption of futile processor by 30% after standby/sleep is due to material interruptions (revealed by Sysinternals Process Explorer). I understand that may be due to problems such as several drivers attempting to control a device (for example, after a faulty update). But I have no idea how find the offending device or drivers.

  My guess is that many owners of this model simply did not notice the problem and they areassuming the poor performance is due to the atom processor netbook. You must use Task Manager or performance monitor to view CPU usage high, and process Explorer to find it hardware interrupts.

  If anyone has found the cause / solution?

  HP, help to resolve this issue please--nobody wants netbooks HP fall into the category "do not buy" due to persistent problems with the futile CPU usage. The HP mini 5102 is the flagship model!

  Ref:

  "Author subject: HP mini5102 interruption high CPU usage after standby Roderick Laird 24 March 2010 04:03:03 GMT - I see of other HP5102 users having problems with high use of the processor of the Wireless Wizard operation amok; I avoided this by disabling the corresponding services. But one problem remains. The system works beautifully/effectively from a cold start. However, if I go back I think that interruptions are consumes about 35% of the cycles CPU. Not something that I want to pass battery on. I made sure that all the drivers are the latest versions according to the HP support site. I also tried disabling the obvious drivers that might be wrong (wireless, ethernet, audio, non-touchpad mouse)... »

  Update the Intel AHCI 9.6.4.1002 driver (iastor.sys) removes the futile CPU usage after sleep from 30% to 20%. This is not in the drivers of HP, but is available at Intel. Subsequently the chipset driver updates might solve the problem. In the meantime:

  Disabling in BIOS Drivelock completely eliminates the problem!

  Apparently users who want a computer that is useful after sleep / summary to know somehow ignore the advice of stern of HP in the BIOS that Drivelock is recommended for safety.

  It cost a lot of time to resolve, with no whatesover help to be published by HP. My consolation is that by systematically eliminating all the bloatware and other services-waste of unused resources, pilots and scheduled tasks automatically loaded on the system (while trying to find the cause of the CPU / interrupt use) I now have a mini 5102 (SSD) that:

  * Cold boots Win 7 Pro 32 in less than 30 seconds (including wireless access)

  * Stops in less than 8 seconds

  * Beds / back in 1-2 seconds

  * Consumes less than 600 MB of RAM at idle

• High CPU usage after upgrading to ESX 4 Update 1

  I just upgraded 2 hosts (IBM HS21 blades) 4 ESX to ESX 4 Update 1, and now I experience high CPU usage.  Before use on each host would turn around 10%, but now after the upgrade, it's about 80 percent on each and now all the virtual machines are running very slow as a result.

  The only change that has been done is that I demoted local readers of hard drives of 500 GB SAS drives to 7 200 RPM 73 GB SAS drives mirrored, 10 000 rpm mirrored and performed a clean installation of ESX 4U1 on each host.  As the VMs 14 are located on a SAN disk array I thought only, it would improve the performance of the hosts.

  Has anyone else had a similar problem or a potential solution?

  See you soon,.

  Josh.

  Seems very strange.

  You have the same number of VM? You have to upgrade the VMware tools?

  There are other changes?

  Local disk is not so important to the overall performance.

• Safari uses excessive CPU after upgrade to Sierra on Macbook Pro

  Hello

  After the upgrade to Sierra, I noticed that Safari uses a lot of CPU, causing the fans to be very strong. I tried almost everything that I could find on this issue, including using Firefox, but nothing has changed. Do I really need to reinstall everything?

• High CPU consumption (always between 12 and 30%)

  I am running Firefox 9.0.1 for Mac. Until the upgrade to version 9.0.1 I had no use of high CPU problems... I've now must constantly between 12% and 30% of CPU and up to sometimes use much further than that, which really slows down my Mac to a point where I have to kill Firefox to use other applications.

  I have a new Mac mini with fast CPU and 8 GB of RAM.

  I tried to reinstall and also to disable the 4 Add-ons I have installed. After a new installation and all 4 disabled add-ons, I see exactly the same problem even with one tab open to google.com

  Any help from the community is very much appreciated.

  Thanks in advance...

  I've upgraded to Firefox 10 and this issue is now resolved.

• Tecra M2 - stop hard on high CPU (turns off with no BSOD)

  Experienced stops consistent when the CPU is running at full during a little while.
  -J' mean 'stops' complete power cut with no blue screen of death where all is lost and the computer must be restarted manually.
  -by "high CPU", I mean when the processor locks to full use such that when you insert a column in a big Excel sheet with errors or if you want a large number of files and you open a video from the network or when you run a registry scan and antivirus analysis at the same time.

  The problem took place regularly for a few months and I can now make a case with greater predictability. Using the hardware monitor suite 'Everest', it seems that the problem occurs when the temperature of the CPU is located at 99 for more than a minute or more.

  This happens with some, but never when batteries run - then attempts to force the error, it will not be stopped if the power cable is released just before the drop point.

  In the cases of the problem, it seems to be a small error message appearing only a fraction of a second before the death of the computer.

  Each reference forum and help that I read would suggest the problem is related material and that the chip or the motherboard is overheating and need replacement. While the laptop is almost 18 months old, I bought a new ' everything except the screen and HDD "earlier this year, and was not prepared to accept the explanation without more tests.

  Kantonix Linux works very well and the CD starts seems to tax the processor as much as the same events that kill for me under XP.

  A few weeks back, I installed Windows XP on a second HARD drive in the Bay of hotswappable and noted the installation seems to work pretty hot computer and he died during the process. It has experienced no difficulties for while but, a few days after moving the HARD drive reinstalled in the primary position and after you have reinstalled a lot a lot of applications, the error started happening again.

  Last night I caught a few fractions of a second before the death, the pulling power and stop the process and allow me to see the error message (as mentioned above):

  -first message came from "TOSHIBA Power Saver" saying "a fatal error occurred at x 06" (not sure about the last bit) ".

  -second message was "THotkey.exe' saying 'could not load powrprof.dll.

  -monitoring of several hundred cases of the second message.

  Because of the error messages, I was not able to get a print screen.

  Solutions or even on ideas that would be very appreciated!

  Hello

  According to your explanations and the information in your ad, I think that the problem is related to the software.
  You wrote something about energy saving. This Toshiba utility controls the speed of the CPU and the use of cooling modules.
  I think that this request could be responsible by the judgments. Try reinstalling this utility.
  In addition, check the configuration of the unique power plans. If you work only with battery energy saver using another mode of power supply as working on AC.
  I think you could check these consumption patterns and configure it.

  Verification of the cooling module is also not a bad idea. Maybe fans cannot work properly because of the dust and debris inside the books.
  I use the vacuum cleaner to clean the fans. CA? s an easy way to make it free of dust.
  But if you get it, you must be careful.

• Satellite A 110 is suspended due to high CPU temperatures

  Hello

  My computer is hung up on me while running certain applications (such as Dreamweaver CS3) or other situations in which work the CPU at maximum performance. I suspect that the reason is high CPU temperatures and indeed download several CPU, monitor applications (like thermal analyst intel) my average CPU temperature is around 61 degrees (Celsius), and before the computer hangs (instantly - just completely stop lose power), it reaches very high and not necessairly after working for a long time.

  My questions:
  1. is this a known problem with this model?
  2. is there anything I can do to limit this problem and avoid data loss?

  Thanks in advance,

  URI

  I think you will need to contact the ASP in your country for assistance.
  In your case maybe the cooling module may not work correctly. Probably the thermal grease that is placed between the CPU and the cooling module must be renewed.

  All these things need to be clarified.
  So call it the ASP.

• High CPU usage by "System outages" and missing keystrokes in IE on all new HP laptop 15-r085nd

  I recently bought a HP15-r085nd (Win 8.1 with Bing), and right out of the box, I encountered this problem:

  After the awakening of the mode (usually after the first time to wake from sleep mode, but always after the second time), the process "System outages" has high utilization of the processor, up to 45%. The laptop then responds very, very slow. In addition, in Internet Explorer (but only in Internet Explorer, it seems!) strikes are missing out.

  I tried the following:

  -Implementation of all the updates of Windows, all McAfee updates and all of the updates from HP Assistent. No results.

  -Reinstall all the drivers, no results. Windows system restore: no result. Factory reset the recovery partition: no result. Then implemented all the updates again: no result.

  -J' tried to use Microsoft Xperf to diagnose the problem: it seems wdf0100.sys to blame for the high CPU usage. (In other words, if I have interpreted the results in the right way).

  -J' then did some troubleshooting with Microsoft Support: they asked me to disable all startup items in the Task Manager and disable all non-Microsoft services in msconfig. The result was that the high CPU usage of "System interrupts" occurred less frequently after the first time out of the way 'sleep', but still she always had after the second time to wake off mode 'sleep'. Uninstallation of McAfee seems to have the same effect, by the way.

  -J' then did some troubleshooting with the store were I bought it. They used a pilot program to install newer versions of the drivers. Also, in vain.

  Then they gave me another laptop of the same model (r085nd). It had exactly the same problems. So I think that all laptops of this model have the same problem! Does anyone know of a similar case with a laptop similar?

  -J' then did some troubleshooting with HP support. We have updated the BIOS (F.24), without result. We have made a few updates to additional drivers on the HP site, no results. We wanted to update the graphic driver Intel HD (sp65598), but we couldn't install it, an error message saying: minimum system requirements were not satisfied.

  I hope that the HP support can arrive at a solution (they wanted to deepen this). If so, I'll promise to post it here, because it affects probably other r085nd HP as well.

  In the mean time, I'd appreciate any suggestions, because I'm totally confused now. Someone at - it ideas? I will answer all the answers!

  I was contacted by HP Support again. After a new series of updates which included some updates everything new on the site of HP is solved the problem with high CPU usage by "system outages"!

  We have done several updates, so I know not that exactly solved the problem, but it is those:

  -New firmware BIOS: version F.33 (my bet would be that is the one that solves the problem)

  -New Intel chipset driver: 1.20 (sp69575.exe)

  -New driver Intel HD Graphics: 1.20 (sp69589.exe): 10.18.10.3958 (this one tried earlier, without solving the problem)

  -New driver Realtek card reader: 1.20Ap3 (sp69610.exe)

  I hope this helps other people with the same problem.

  Thanks to the HP Support team for their help with this problem!

  Moreover, the problem of lack of strikes in Internet Explorer (more use of CPU (any reason), the sequences of keys more are not registered!) still exists! I work around this problem by using Google Chrome. Again, I hope that this issue might get resolved as well! I nevertheless marks it as "Resolved" as the main problem is resolved.

• High CPU Powerconnect 6224P - envMontask and boxes Req

  Hi all

  A for our Powerconnect switch has very high CPU usage, about 96% average.

  There are only two processes that generate this use: envMonTask and Req boxes each about 46 to 48%

  

  

  As they are followed by process, I don't know what can cause this CPU usage and how to solve this problem,

  I remember recently 10 gigabits is installed when the switch is on and after that nothing has been restarted, would that be the reason?

  Duplication of port is configured on a single port

  Thank you for your help

  The rear modules are not designed for the addition with the switch, so even if this is not the cause of this, unplug the switch before you add modules is the recommended method to add. EnvMontask and BoxReq are for surveillance of the fans and the temperature, so adding a module could be the cause. With what is a PoE switch, it could be a device drawing too much power.

  Reloading is probably the best first step to take. In addition, remove the module and update firmware would be the next steps. Is probably not a device connected, but unplug the cables and see if it causes a change in the CPU usage can also be useful.

• Windows 7 update - slow download, svchost high CPU usage

  I have a problem downloading by using the Windows Update application. This problem started after January 2016.  In the past, the request of update seems to work without the use of the svchost high CPU and with a reasonable download time.  There is usually a delay until the download has started, but then they ended quickly.

  I have 4 computers: 3 running Windows 7 Pro (CPU - Intel dual, i5 & i7) and 1 running Windows 7 Home (Intel i3).  If the problem is not related to the CPU hardware as best I can tell.

  My update setting is 'check for updates but let me download and install ".

  The Windows Update process includes 3 steps:
  1. identify the important and recommended updates for your computer.
  2. the selection and download updates.
  3. the creation of the restore point and of the installation, the selected updates.

  My problem is step 2, download the selected updates.  This happens on all 4 systems, and I do not expect a download to be this CPU load.  The download time is too long on all systems 4.

  My online search for answers has been frustrating, but several posts said search for viruses, malware and Trojans.  I ran Malwarebytes (free), Windows Defender, Norton Security and ESET (online) on systems and no objects are found.

  My most recent experience involved my Lenovo 7847 system (Intel dual core). Monday, May 23, I checked the updates and there were 15 updates important and 3 optional updates listed.

  After reviewing the updates, I chose the 15 updates and started the download process.  The svchost.exe that is associated with the update happened to 45-60% CPU usage, update status showed no size or % finished and the task manager - network or explore the process did not show any activity download for a long time.

  Finally, after about an hour, the update showed the download size and the % downloaded.  Svchost usage remains high during the time of whole download.  Once the download is complete, the restore point was created and updates have been installed, who also took some time (but it would be I/O CPU & Drive dependent).

  The download status has not changed during most of the time that the download process is running.  The Task Manager and process explore both show very little network activity up to that very near the end of the download procedure. There is therefore no real indication that the process is blocked or just turn very slowly.   It almost seems that the Microsoft servers are overloaded, they delay the download for some reason, or the process svchost and sub-process fail to create good handshake with the server for download.

  My Questions:

  1. Why is svchost usage so high when nothing seems to happen?
  2. Why does take an hour or more to download the updates?  These aren't the huge file sizes, and this attempt to update was almost 2 weeks after Patch Tuesday, then Microsoft servers should not be overloaded.
  3. Why is the situation unchanged for so long during the download process?
  4. most important, what can I do to change this situation?
   
  Thanks in advance for your help.

  My 'update problem' seems to have changed.  Checking updates takes a lot of CPU resources and a lot of time.

  We will leave well enough alone for now. [It took 3-4 hours for MU download/install updates of June on my Win7 boxes].

  But please bookmark this thread. If the behavior persists in July - and especially in August, respond to this thread instead of starting a new. Good luck!

• Windows 7 high CPU wuauserv

  I was just going about my day when I noticed abnormally high CPU usage, something has been using 12%.

  So I check my monitor of appeal and wuauserv was the problem I read it was the windows updates

  so I let it run.

  It does not stop so I restarted and then I stop but it kept rebooting and everything would not stop so I went to check updates tab

  and he was stuck on checking for updates, so I've restarted and my pc this time stop wuauserv always does the same thing but

  This time, he said no update necessary so I tried to install optional updates not important to see if it will address the problem

  but it was stuck at 0% and it's premiering in atm im do not know what to do any help would be greatly appreciated thanks.

• Windows Update causes high CPU AND not let me install Windows 10

  Windows 7 update has several issues:

  1 Windows Update Service causes the CPU usage high - CPU usually works 50% or more with a single SVCHOST.exe running.  I click with the right button on the SVCHOST entry in Task Manager-processes and saw all the services that SVCHOST is still running.  One at a time, I stopped and restarted them.  Finally, when I stopped the Windows Update service, the cpu immediately fell to almost nothing.  I rebooted and tested several times, and each time, it was Windows Update service that was causing the high CPU.

  2. Windows 10 Upgrade Advisor says I could upgrade to Windows 10, and get the icon Windows 10 is in the toolbar.  But it has failed to install several times.  Now, after stopping and restarting the service of updating (and I checked, it is started), the window get Windows 10 rises, is empty and goes.

  3. I ran the Update Diagnostic and got 1 error:

  Windows Update error 0 x 80070003(2016-04-04-T-04_56_09P)

  the Details of the Diag Windows Update window said:

  RootCause: RC-DataStore

  Error code: 0 x 80070003

  4. I tried to launch the 'Fixit' for update, but it did nothing.

  5. I tried to update Windows Update WindowsUpdateAgent30 - x 64 .exe Agent,

  but it fails with this message:

  "Windows Update Agent Installer has met a fatal error"

  6. when I try to start Windows Update-check for updates, it displays the dialog box "check for Updates" and activity indicator green runs and runs and runs for more than 10 minutes but nothing happens.  And when I check the view update history, it shows no updates, even though I know that I've run a LOT of updates in recent years.

  7. I thought to reinstall Windows 7.  I went to download from Microsoft, and when repair installation it activated my key it says that it wasn't a retail version, so check with the supplier (in this case HP).  I checked with HP and they said that this machine was is no longer supported.

  8. on the way I've renamed the folder C:\Windows\SoftwareDistribution-Windows SDOLD, force it to create a new (probably why it does not find the old updates).  IT did not help.

  So it seems to me this machine is expandable to 10 Windows (it meets the specifications and the Advisor to update Windows-10 said yes and installed the toolbar).  But something is wrong, probably with Windows Updater, and now nothing will be update or upgrade.  And I can't get a new copy of Windows 7.

  So, any thoughts?  I'm out of ideas.

• Use high CPU (35% average) while System Idle process CPU about 98% but frustrated by "[name of the prog] has stopped working".

  Hello

  I am trying to help someone with a laptop HP model g6-1202sa (Windows 7 Home Premium 64 - bit, another record at the end of the post).

  I think that Windows is now updated and drivers, but the problem remains also.

  The laptop has the symptoms mentioned in the title I found the Manager tasks.  Laptop fan is on a large part of the time, and the owner says that, during the execution of something more intensive than Skype for example of internet browsing, they get a warning from Norton on high CPU. Resource monitor shows that system interrupts are on average about 31% CPU.

  The results, I found the task manager has led to some research on Google, which in turn led me to want to run adksetup.exe (Windows Assessment and Deployment Kit) in the hope of discovering if a particular driver is causing the problem. (Various threads on the internet point to what is the way to go).

  However, after downloading adksetup.exe, when I try to launch it I get the initial screen of Toolbox and then 'assessment of Windows and the deployment for Windows 8.1 Kit has stopped working ". (Verification of the solution finally gives the only option to "Close the program").  Similarly, I have now discovered that if I try to look at the properties of the computer, i.e. start > right click on computer > left click on properties, I get "Windows Explorer has stopped working". Do more research on Google I find sometimes I get "Internet Explorer has stopped working" sometimes (Chrome is ok).  More out of curiosity than anything specific I ran AMD VISION Engine Control Center after right click on the desktop and ended with 'Catalyst Control Center; The host Application has stopped working".

  So before going any further, does anyone have any ideas what's happening?   I do not understand the problems 'has stopped working"in safe mode, but the high utilization of the processor with System Idle Process around 98% is still there.  It appears so that I can run adksetup.exe in safe mode while this would be the way to proceed and continue to try to tackle the problem of CPU?

  For the record, some of the things I've done along the way include update of Windows, updating drivers, running the file system (no violation of integrity) checker, a regular chkdsk ("CHKDSK discovered free space marked allocated in the master file table (MFT) bitmap. Correcting errors in the volume bitmap. Windows has made corrections to the file system").  Swapped the only module memory 4GB 2 x 1 GB modules I had to hang out, all the symptoms remained 4 GB then reinstalled.

  As you can see there are at least a dozen of them which are probably related to the high utilization of the processor.

  The drivers are not updated (Bet you checked in the Manager device or with a sweeper driver as app)

  To be honest I don't see how SFC returned no breach of integrity account required to this type of problems.

  It might just be easier to re - install win 7, but I'm happy to help anyway

• Cisco 4506 high CPU usage

  Hello

  Yesterday afternoon, one of our 4506 switch has climbed to 96% CPU usage. I did not the configuration changes. Here is the process with high CPU usage

  Hello Salman,

  If DHCP requests are taken over by clients, you will probably want to focus on the limiting of requests DHCP using DHCP snooping.
