DELL Precision 7650 - unknown items in Device Manager

Hi, I have problem with my new DELL Precision 7560 laptop. I already installed all drivers and updates using DELL Support tool, Windows Update and Intel support tool, but still I have 3 unknown devices in the Device Manager: 

- PCI Device

Device PCI\VEN_8086&DEV_43A4&SUBSYS_0A691028&REV_11\3&11583659&0&FD requires further installation.

- SM Bus Controller

Device PCI\VEN_8086&DEV_43A3&SUBSYS_0A691028&REV_11\3&11583659&0&FC requires further installation.

- Unknown device

Device ACPI\INTC1051\2&daba3ff&0 requires further installation.

Do you know what additional drivers I should install to solve these issues?

Update=That driver helped with 2 of these unknown items.
