HP C640 Dratini - Drivers missing

Hi folks,

I have installed all the drivers that are available for dratini.
I am using windows 11

In device manager I am seeing 3 devices that are Unknown device state or no drivers

  • Base system device - VEN_8086&DEV_1911
  • Unknown driver - ACPI/ACPI_DT_NAMESPACE_HID
  • Unknown driver - ACPI/PRP0001

Any ideas?

Thank you,

Any functionality missing aside from the known issues?

Some devices will always show as not working thats expected, but im not sure how many there are exactly on CML

I haven’t fully tested yet. But, it’s little annoying
