SM Bus Controller driver

[brettintherye]

Hey all!  I have a XPS420 and I've got the yellow exclamation point next to "SM Bus Controller" in my device manager.  I downloaded the chipset driver and installed it but the exclamation is still there.  Do I need a different driver?  ANY help would be much appreciated!

Hi Brettintherye,

The yellow exclamation point is an error, not a missing driver. Open the device to see what the error is.

[brettintherye]

it says "The drivers for this device are not installed. (Code 28)

To reinstall the drivers for this device, click Reinstall Driver."

I have the original cds that came with it.  Should I try those or is there a more up to date file online?  THANKS!

I also tried "reinstall driver" but it couldn't find one online

You need to install the Intel chipset driver.

I did.  I also noticed an improvement in performance after I did this but the error is still there...

Double click on the SM Bus Controller with ? or !  (Assume it shows under Other devices?) go to details tab -> Change the drop down to Hardware ID - Post the info given below in the box. We can find the driver based on the info.

Also try this

ftp.dell.com/.../R174616.exe

Uninstall the SmBus controller that shows ! mark - Choose scan for hardware changes and see. Try rebooting the computer after the installation.
