  • Pavilion G4 w / AMD processor - where can I find a driver for the SM Bus controller?

    Bought a G4 Pavilion - 1164CA and upgraded the HD with SSD

    and did a new install of Windows 7 x 64 Premium.

    The model has a processor AMD A6 - 3400M.

    Device Manager shows that a driver is missing for SM Bus controller.

    I checked the drivers HP page for the model but no chipset or the SM Bus controller driver is...

    http://h10025.www1.HP.com/ewfrf/wc/softwareCategory?OS=4063&LC=en&cc=us&DLC=en&sw_lang=&product=5148...

    Note: I did a clean install of Windows 7 x 64, not a recovery, read a recovery to a smaller HD would not be possible and also would prefer a clean without all the extras install as the SSD space is limited at first.

    Suggestions to find a driver for SM Bus controller for this model with an AMD processor and chipset?

    Looks like the SM Bus driver is part of the graphics driver.

  • HP Pavilion dv6-6b26sa Windows 7 - SM Bus controller driver missing

    Hello

    I have a HP Pavilion dv6-6b26sa.

    I love the laptop.  I did a clean reinstall of Windows 7 64-bit.

    Everything installed perfectly, except the SM Bus controller - I have a yellow! next to him - no drivers...

    I did the update of the autopilot in the Device Manager, found nothing.  I read that some people have tried to install the latest AMD / ATI graphics and chipset drivers.  So I made this using automatic detection and install the AMD software - he advised that I have installed the drivers of mobility.  Yet the SM Bus controller has no driver.

    Can someone help me?

    Thank you very much
