Missing Notebook hardware drivers

[RandallW]

Installed Windows 7, applied all available Windows Update, the following hardware drivers were not installed:

• Ethernet Controller
• SM Bus Controller
• (Unknown Device)
• AMD USB 3 Extensible Host Controller

Please let me know where I can download these drivers.  Thanks.

Hi:

For the smbus and usb3 controllers, download and install the AMD Chipset drivers and restart the PC.

You want the first file listed on the webpage.

Ethernet:

This package provides the Realtek Local Area Network (LAN) Driver that enables the Realtek Network Interface Card (NIC) Chip in supported notebook models that are running a supported operating system.

File name: sp71268.exe

In order to provide the driver for the unknown device (there can be a few devices that show up as unknown), please post the hardware ID for the unknown device.

To find the hardware ID, click on the Unknown Device in the device manager.

Then click on the Details tab at the top of the unknown device window.

Now you will see a Property drop down list and it will be set to Device Description.

Drop down on that list and select the 2nd item (Hardware ID's).

Post the top string of characters that you see in the window.

Thanks.  Using HP Support Assistant cleaned up the Unknown Device.  The other links you provided worked as expected.
