COM Bluetooth port 90-100% CPU load

I ' am running a PC application via a COM port normal, nothing complicated 38 kbaud. The CPU load is about 4%.
Then I try to do without this thread, that oops the CPU rises to 96% of the load.

I use a different computer manufacturers with Toshiba stack and module internal BT. Win XP SP2. Yes I have updated to the last stack of Toshiba.

The same problem on my second computer (since it is a dual core I get 50% CPU) also with Toshiba stack.

If use an external RS232 Bluetooth adapter everythings works fine at 4% of CPU load. I have however to connect a USB Bluetooth, same problem 96% CPU adapter.

I'm doing something obviously wrong?

/ B

Each laptop manufacturer typically feature test prior to the distribution of laptops. Have you tried to know what say the support from the manufacturer of this problem?

I use for Toshiba laptop and BT works well and something like that doesn't happen to me.

  • Ghostery addon causes 100% CPU load on a carrot for a few seconds for each hyperlink that you clicked.

    For many months now and with several versions of Firefox and firefox profiles, turning the Ghostery add-on causes each hyperlink clicked to have 2 second break. In the Task Manager, I see 25% cpu usage, which equals 100% of CPU on my Quad Core cpu load.

    If I disable Ghostery and restart Firefox, all problems disappear. So I have either the choice between a slow browser, or privacy-enabled navigation. Both are unacceptable.

    I can't find anyone with this problem; is it me?

    I did not use of Ghostery but I guess it could be the preload page and inspect and possibly break URLS to protect you before posting. Maybe if you set the settings so that it does less, allows you to balance the objectives of performance and privacy?

  • BT stack file TosBTMng.Exe generates 100% of CPU load

    I am also facing the problem that the Toshiba Bluetooth Manager (TosBtMng.exe) very often starts a loop and causes a 100% CPU load.

    This has happened with older versions of the Toshiba Bluetooth stack and the current version (5.1.0.12).

    The affected system is a Tecra S1, BT-Modul and Windows XP SP2.

    BT battery installation went well and the laptop starts succesfull while BT is enabled. I also checked for hidden COM-Ports and other tips in this forum, without success.

    Blocking seems to occur at different times. Sometimes just after are restarted, by clicking on the tray icon of BT with the right button of the mouse. Then the context menu is shown all too the white box, no entries. He can also try to connect to a device already associated. If I kill the process with the Task Manager, I can restart and he continues to work for a while.

    As found in another thread here, I enabled the registration of the API of the Bluetooth Manager and found the following when connecting with the Nokia PC Suite for my mobile phone:

    A new COM port is created successfully (COM23) and a few seconds later the CPU of TosBtMng load goes up to 100%, but no API calls are made. And if you wait long enough the phone are connected and data can be transferred. However, very slowly.

  • RT FIFO results in 100% of cpu load?

    Hello

    I am trying to replace some RT-FIFO queues on a target of cRIO9074 (via LV2011), which should be fairly easy because the API is very similar for both:

    This example VI works for sure: the lower loop puts an I32 in the FIFO every 100ms, the upper loop must wait before trying to read a new element of the "timeout" (the value 50ms) FIFO. For this example the upper loop should run (roughly) 2 - 3 times for each iteration of the lower loop because of 50ms timeout.

    The problem I have is: it shows 100% cpu load and I don't understand why he says:

    Where this example VI does not burn 100% cpu load? The RTFIFORead question just the current state of the FIFO?

    Have you checked whether a time-out to > 100ms also creates 100% CPU load?

    Please note that create the FIFO provides the configuration of reading and writing for the vote against blocking. See Help for more information.

  • 100% high CPU load and memory usage

    Hi all

    My company bought a new appliance IPS 4510 and after initial installation, I see that the CPU load and memory is 100%. The device is not in a production network. Is this normal or there is a hardware problem? Enjoy a Counselor about it.

    Concerning

    Christine

    Hi Damien,.

    It is actually normal behavior for an IPS sensor.

    To measure the actual load of an IPS sensor, you will want to monitor the "percentage load treatment" of the analytical engine that processes all inspection processing for the sensor.

    You can view these statistics by using the command 'display the scan statistics-engine '.

    Also, the sensor running version 7.0000 E4 5,0000 E4 (or later version), you can check the load percentage value Inspection displayed by the command "Display inspection-load" in its place.

    Hope that answers your query.

  • Windows Update Service consume 100% of load on a kernel (Windwos 7)

    Hello

    This Monday week Windows update service (wuauserv) is constantly consuming 100% of load with one heart. The system is completely updated, all the updates are applied. I know that Windows update is generally the software kind of crap (sorry guys, but there are a lot of things to improve) and usually consumes CPU high for a long time just check the updates (installation also last very long), but this time he keeps everything simply.

    Restaring the service did not help. Restart does not help either. I tried to re - install all the com - dll, restarted the service,... nothing helps. Then I tried to apply the tool but this Fixit tool seems to be "smart" enough and starts the wuauserv service in order to detect problems--> same charge again.

    My system is Windows 7-64 and is usually very fast (Core - I 7, 2.6 GHz, 8 GB of Ram, 512 GB SSD) is NOT the PC.

    Thank you

    (2) disable graphics hardware acceleration in Firefox and Flash

    (A) in Firefox, uncheck the box here and restart:

  • Satellite Pro T130 - 14L: 100% CPU use of acpi.sys after changing the HDD to SSD

    Hello

    because I changed my for one SSD HARD drive and reinstalled Windows 7 with 64 bit on this subject, my system works frequently in 100% CPU utilization caused by kernel module acpi.sys, I discovered with process Explorer and confirmed by recording an ETL file.

    This problem occurs once an hour on average, sometimes after 10 minutes of functioning of the system and sometimes after two hours, no matter which programs are running and whether or not I is actively using the computer. When I noticed a hanging and see this 100% cpu core in the process Explorer window are currently in use, I always need to save my work (which may take a few minutes) and restart the computer.

    I could live with that, but it's pretty nasty. My bios is up to date (version 2.70), as well as my other drivers (no error and no virus found). In other forums I've read, these problems could be avoided by changing the energy registers something Windows settings as never go to sleep of the SSD, but it works in my case as I disabled all energy saving options in Windows and I still have this problem.

    Is there maybe an update of the unofficial bios that could solve this problem?
    I read in another forum, that an unofficial bios update Dell fixed a similar problem on a Dell computer.

    Can someone help me solve this problem please?

    Details of process Explorer:
    The wire with TID 160 and the start address:

    ACPI. SYS + 0X1AF7C

    suddenly starts using 100% CPU and does not stop until you restart.
    Similar problem as in this forum for a Dell PC:
    https://social.technet.Microsoft.com...UM=w7itproperf

    Unlike the Dell problem, there is no appropriate-updated bios for me, could you help me if you could tell me how to stop the kernel module (if it starts hanging or even before). Then I could at least avoid frequent restarts.

  • In the latest version of Skype's huge CPU load

    I have installed Skype on 2 different PC running Windows (freshly installed) 8. When using Skype in combination with Chrome CPU load goes up to 100% of all the minutes or more for a few seconds. It's really irritating and my not-so-rare configuration tells me that more people should have this huge problem.

    The only way to stop this behavior must close Skype. I read the topics (from 2012 and 2013) on how you can disable interaction web browser in the Skype settings, but it does not work (or more).

    Development of Skype in recent years is just tragic

    As of October 15, 2014, with the last update of Skype these amazing huge bugs seem to have been fixed after many, many months (years?). After you install the update and change nothing else on my system, Skype seems fine now. No freezes, no more huge processor and the burden of memory, leaks memory is no longer. Amazing that it took so long to get it, but hey, Microsoft can't complain now that it works.
