My Device Manager currently shows an (!) next to the following:
(!)SM Bus Controller
Cause of problem:
I recently had to install a new hard drive on my HP DV9700. After doingso, I had to install the drivers for all my internal hardware manually from the HP website due to the fact that I nolonger have the original disks that came with the computer.
I managed to get everything up and running except for those two issues.
I've tried updating the drivers for both and the action has rendered unsucessful.
How do I fix this?

I would download the chipset driver from Intel to see if that makes the SM Bus controller issue go away.
Normally a missing coprocessor driver is due to a video adapter driver being needed for the GPU.
Since you haven't provided information on what operating system you are running, it is difficult to provide specific help.
So what you can do to help me help you is this:
1. List the OS you are running and if it is 32 or 64 bit.
2. Click on each missing device in the device manager. Then click on the details tab. If you are running XP, post the top string of characters you see for each missing device.
If you are running Vista or W7, in the Properties drop down list, select the second item (Hardware ID's). Post the top string of characters you see.
That batch of numbers and letters will identify the manufacturer and model of the missing devices in most instances.
With that info, I can try and find the applicable drivers for you.

Also, I just tried downloading the chipset from the link you provided and that was unsucessful.
I received an error message stating that my system did not meet the minimum requirements
and that the setup would now exit.

OK those device details reveal it is an nVidia chipset but I don't know which one because there are over 100 dv97xx models.
The dv9700 model has a Mobile Intel 965 chipset, which is why it didn't install on yours because yours has the nVidia chipset.
I believe this is the driver you need so give it a try:
If not, please post your exact model number from this list, and I'll see what I can find.

I upgraded to windows 8. I have an hp laptop. DV6338se. I have the same issue with Coprocessor and SM Bus Controller.
It worked for 2 months and then stopped working. I did not make any changes to my files or didnt install new programs. not sure how this happened...but i tried re-installing the nVidia files and it says that they were already there so i chose to override the existing and still doesnt work. I have tried newer drivers but it says that im not using correct operating system.
I cant figure out how to fix it, i know its possible since it worked for 2 months then all of a sudden stopped.
Apparently they control all 3 of my usb ports and now i cannot access my iPhone or external hard drive or mouse.

I upgraded my original HP Vista now W7 AMD 64bit Notebook dv9620ed to Windows 8 64 bit.
I found following driver for the PCI\VEN_10DE&DEV_0543&SUBSYS_30CF103C&REV_A2
File name: sp37730.exe (22 MB).
Installation doesn't work because it is for Vista. Hower the package is extracted to C:\swsetup\SP37730. The Trick: Goto Device Managerer (Right click Computer; Properties; Device Manager. Go to the yellow exclamation mark at Co processor, right click and search from there for the C:\swsetup\SP37730 folder and open the WinVista64 (or 32) subfolder.
Finish it. Now the Yellow Eclamation mark has gone. So the driver is OK but the installationprogram is not. Hope this helps.
