I'm a newbie to this forum so maybe my problem seems abit trivial to some of you guys but its been keeping me busy for 3 full days now.
I recently installed windows XP pro. on my HP 6735s. I managed to find all the drivers online on HP website but I did not find any driver for "SM Bus Controller"
and this is the only component in device manager which is not installed properly and I have no idea what to do about it. I googled it and tried all the websites I could think of but didn't find this driver.
any help would be greatly appreciated.
here is my system info:
Model: HP Compaq 6735s
OS: Windows XP Professional
Processor: AMD Athlon X2 DualCore QL-62 2.0 Ghz
ATI Radeon HD 3200 Graphics

I just want to ask two questions of you regarding your 6735s laptop, since I own the same machine and has the same problems. (Win-Xp OS)
How were you able to install your sound card correctly? Whatever driver I install, the driver manager keeps telling me that "a modem on High Definition Audio bus" is an unknown device. What driver do you use for audio?
Were you able to fix your error with ATI SMBus? If yes then what did you find as a fix? I found a download at HP's website (sp29374) for this known issue, but the issue itself was for Pavilon laptops and such, and since the file is a BIOS flash/update, I don't realy want to just test it out on my 6735s.

Did you install the MS UAA driver for your audio card?

But check this post from me please, it describes the problem with some more specifics.:

I think we are overlooking the obvious here.
You say the missing device states it is a Modem on High Definition Audio bus... well, here is what I looked into.
First, I looked at the driver download page for your notebook. There are no modem drivers.
Then I looked at the quickspecs for your notebook, and indeed the specs show where a modem jack is on your notebook and it lists that the notebook comes with a modem.
Well, since there are no modem drivers listed, I did a seach on the internet for 6735s modem driver and found several postings about this problem.
One posting led me to this link to download modem drivers which supposedly will fix your missing modem problem.
Please give it a try and let us know if that solved the problem.

I have the same laptop and I believe the same problem.
I cannot connect to the internet through LAN, only wireless. I have installed and updated every driver. The only device in device manager that is not running properly is Other Devices - SM Bus Controller. The network card is not being found yet the laptop recognises that there is a cable plugged in(the lights are flashing on the port)
I have checked the BIOS and it is enabled.
This problem has only appeared since I replaced Vista with XP.
I'm really unsure how to fix it, does anyone have any ideas? Thanks.
