HP ProBook 455 G2

What can I do?

Hello:

You will probably need to manually install the driver.

I know that is the one you need, because if you look at the contents of the driver file folder you can see that this driver has support for the hardware ID you have posted.

[AMDIOV. NTamd64]
% IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1002 & DEV_5A23
% IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1419
% IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1577
% IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1423
% IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1437
% IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1449
% IOMMU. DeviceDesc%=NULL_DRIVER,PCI\VEN_1022 & DEV_1611

Sometimes the automatic installer does not install the driver, so you must outwit the PC.

Go to Device Manager and click on the device IOMMU requiring the driver.

Click the driver tab.  Click on set to update driver.

Select her browse my computer for driver software option and navigate to the folder of the driver that was created when you ran the file.

This file will be located in C:\SWSetup\sp67924.

Make sure that the include subfolders is selected and the driver should install.

Restart the PC.
