Re: HP PROBOOK 450 G5 da0x8cmb6e0 need ratings components
The referenced parts appear to link to the USB connector and specifically, the EMI shield.
Review the following reference diagram and you should be able to trace the pads to confirm that these parts are for EMI grounding of the USB metal shell / pads.

Re: HP PROBOOK 450 G5 da0x8cmb6e0 need ratings components
If you are confident that the resistor is on Vbus then it is a bleed resistor to allow for the Vbus to discharge to 0v when it is not powered / local USB load switch is OFF on the PCB.
Apply a 20k-30k resistor that can fit onto this size of pads. Try 0402 or 0603 SMD size for this resistor.Comment
