Bus SM driver and USB Ports can Point of Yellow Exclamation

H8-1020 Desktop

Windows 7, 64-bit

Looked in Device Manager and that's what I see:

Bus SM driver with yellow exclamation point

The USB drive letter even have

Looked at the HP website for the Chipset drivers and only saw the BIOS drivers.  Tried this update.  No change.

A run DXDIAG.  Don't see where USB or SM Bus drivers are listed.

Note the system has a discreet graphics card.

Other suggestions?

Thanks to all the proposals.  But good ' ol Google saved the day.  I googled "hpe sm bus controller driver update" and it adds Windows 7.  One of the HP forum reply recently was to go to the Intel download page and download the Intel chipset drivers.  Did.  Exclamation point is more ugly next to the SM Bus controller.

Don't you think that it would be under the drivers for the MOBO or BIOS?  Or Chipset drivers?

The audio device is another problem.  Looks like the sound card has a dead chip.  Installed a new card his discreet and now music to my ears.

(Historical note: it all started when the original Pegatron Carmel mother died.)  Ordered a new one on ebay (same model and revision).  If I had the Intel chipset first, I wouldn't have had to wipe and re-install the operating system.

Thanks again.   I always learn a lot!

  • HP ENVY 17 t-k000 CTO Notebook: 1missing driver and USB ports Plug and unplug every 5 minutes on the left side

    This laptop has 3 USB ports and the 2 on the left side to keep disconnection and reconnection, but recently it has begun to cut the full power of the 2 on the left even if I use a different mouse it will even turn and I have to use the touchpad. I tested with other mice, and the issue remains the same for the USB ports.

    I was told 2 solutions where I have to reapply thermal paste and take it apart to remove the dust in the motherboard and fans.

    The second solution is to get the driver missing 1 of Device Manager and make install in the hope that the USB ports are linked to it. I reinstalled the USB 3.0 driver and he got one of them then down to 1.

    Power management suspend state link and selective are both disabled so this isn't the issue. And my computer did not freeze or close from overheating what happens in computers with severe cases of overheating.

    Need help.

  • Driver files that run the parallel port and USB port

    In the system information utility where to look to find the parallel port and the port driver USB, name of file that manages these?

    Know the drivers specific, is only half the story.  Why you looking for these drivers?  You have problems with your parallel port or USB port?  This can be caused by problems with drivers or it could be a hardware problem (hard to diagnose a hardware problem without good parts to swap and test).  If you need to update the drivers, you must use device (not msinfo32) Manager - or maybe clicking on an executable file that loads the drivers automatically (depends on how it is sent by download).

    Go to the Device Manager by going to start / find and type Device Manager and enter and then double-click on the program icon that appears.  Check each device to a red x, yellow! or white?  These identify devices with problems probably (drivers, but also of conflict or something else).  Click on each for more details and troubleshooting tips.  If you need drivers (I assume that you want to the parallel port and USB ports), get the computer dealer or the manufacturer of the device (NOT of Microsoft Updates).  In fact, you must disable automatic updates in Windows Update driver as follows: http://www.addictivetips.com/windows-tips/how-to-disable-automatic-driver-installation-in-windows-vista/. Follow these steps to get the drivers: http://pcsupport.about.com/od/driverssupport/ht/driverdlmfgr.htm.  Once you have the drivers, you can install them via the Manager device as follows: http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html.  Or run the Setup program of driver provided by the vendor of the computer or the manufacturer of the device.  Be VERY careful get Vista compatible drivers for these devices are difficult to identify (they usually come with the numbers of model or something like that if they can have serial numbers) and using the wrong drivers could make the problem (whatever that is) worse.

    If you update the drivers succerssfully and the problem persists, then it is probably a hardware problem.  In this case, contact the manufacturer of your computer for technical support (hopeully it is still under warranty) or bring it to a professional computer repairman (NOT Geek Squad or one of those big store centers because they don't really know what they're doing and charge a lot for this level of expertise) to have the components tested and possibly replaced.

    I hlpe that aid.

  • Satellite M30-604: USB Port can not find the driver

    Hello

    I keep having the same problem on my Satellite M30 604 when connecting to a USB device.
    It does not really matter with this kind of device, the problem still.

    Whenever I have insert the USB plug into one of the slots, my home XP keeps popping up the wizzard software.
    Even with devices without drivers such as USB keys, it keeps bothering me and finally tells me that it cannot find the right driver.

    If I try to install a printer, it installs the software found, but finally stops the operation because it can't find the driver (?). I don't know in what direction I should look at to solve this.

    So if anyone can help me on this, I would be very grateful!
    Edwin

    Hello, Edwin

    It's very strange because it is not necessary to install a USB driver and standard Microsoft USB driver should work well. I put t know if this can help, but please check this page

    This fix is also part of the factory settings (recovery image on the delivered CD). By the way: your device is about three years old and it will be interesting to know since when you have this problem. Just for example: I have more Satellite 1900 with USB 1.0 and use USB keys and drive external HARD without any problem.

  • Satellite P200 1EE problems with playback HD video and USB ports

    I bought the laptop Satellite P200-1EE dixons for and I'm happy with it in many ways, but the main reason I bought the 1EE P200 was because of its potential to play and edit the video high defintion.

    I can't seem to play or watch video clips high definition without them being clumsy and with a frequency of images at 3 frames per second, and not the 30 frames per second, he must turn.

    The clips I'm playing are some MOV files record on my camera at 1280 by 720 resolution at 30 frames per second and the two Quictkime player and Realplayer they simply are not quite smooth. Given that the laptop has a DVD player high definition and a high-end graphics card ATI HD 2600 ispecifically intentional for high defintion watch a DVD high defintion to 2040 by 1080 I do not understand why he should fight with playback relatively low resolution video files.

    I would edit 720 video high definition and the speed of the processor, the speed of the bus, ram and graphics card should be enough for this high defintion video simple editing, so if he can not even play video high defintion, what chance does he have to edit video high defintion?

    After only 2 days of working completely fine Vista Vista completely crushed and the computer refused to restart. I had to use the recovery disk and completely wipe the hard drive. not a good introduction to vista which, apart from that, it was very slippery. After you have installed Office 2003 it works completely fine on Vista Home premium

    Does anyone have suggestions or solutions?

    Hi Daniel

    To be honest you message confuses me.
    The recorded movies (.mov files) are not format true high definition as in movies on HD DVD or Blue ray!

    I think you need to convert these files first in a format mpeg mov or avi format and then you can try to play with ordinary players like WMP, Real player, etc.

    Here are some useful tools;

    Converts mov to mpeg
    http://www.radgametools.com/binkhcon.htm

    Convert mov to avi
    http://www.JakeLudington.com/ask_jake/20051003_convert_mov_to_avi.html

    With regard to the question of the USB.
    Try to remove the USB port on the Device Manager and restart the laptop. After restarting again the USB ports should be recognized again and the USB driver should be updated.
    In most cases, this enables the USB flash drive.

  • Installed Windows & 32 Bit drivers and USB ports don't DO NOT WORK.

    I bugh a laptop HP Pavillion 14 TS who came to preinstall Windows 8.1 64-bit I hate so wiped the drives and installed Windows 7 32 bit and now I have a big problem.  None of my network drivers work and 2 uSB ports where I plug in my mouse and other devices of SB to do more work.

    I did a back up of the established SW leader who has all the HP dvers for my laptop but will not install the network and video of divers. And when I try to install the drives, I get the error message saying that they are not compatible with this version of Windows.

    I loked on the HP site under my model of laptop that s as above, but HP don't do my notebook drivers for Windows 7 32. And I looked on both the Realteck site for network wireless Realteck and Ethernet Realteck drivers but none of them work or install on my OS. Intel video drivers do not work either. So I'm really stuck one I can not return to 8.1 Windows as if that 32-bit Windows 7 works on my laptop but most of my drivers is not compatible with the operating system and I don't want not to install 64-bit Windows, I like 32-bit.

    Drivers that do not work on Windows 7 32-bit are:

    Realteck RTL8188EE 802 - 11 b/gn witeless lan

    Die Ethernet Realteck and

    Intel High definition graphics driver

    That don't work at all under Windows 7 32 bit because they are the only 64-bit drivers.

    So can you please post me a link network bth and drvers of graphics from Intel that works with my laptop. I tried many different drivers Realteck and raphics for Windows 7, but none of them DOES not work on my system. And none of my USB ports are no longer works. So, how can I fix this?

    Hello:

    Should be no problem to get W7 32 bit to work on this model.

    Just use all the drivers and software from the HP Probook 450 G0 on your model, except the Audio, BIOS and firmware files.

    Your model uses only the Intel HD graphics driver.

    The first pilot, you need to install the Intel chipset installation utility and reboot.

  • XP hangs after connecting an external hard drive via USB port

    When I connect an external hard drive of 250GB via a USB port on my system XP - SP3, the computer crashes immediately after the sound signal from the recognition of a normal connection PnP. There is no assignment of the station. I don't know that he had worked as can be expected before. A new 500 GB external hard drive is recognized as new hardware, the driver installed and ready to use, but after that, the PC shuts down completely new. However, when I do a system startup after connection of the same two drives, everything looks OK. Also, no problem with a USB stick of 2 GB. How to find what's the problem?

    Well - it's Windows for you, sometimes. :/
