Product: HP EliteDesk 800 G5 Desktop Mini PC
Operating System: Microsoft Windows 10 (64-bit)

The USB power state mappings for the USB root hub appear to be incorrect using BIOS 2.13

 

Power capabilities:
0000005D
PDCAP_D0_SUPPORTED
PDCAP_D2_SUPPORTED
PDCAP_D3_SUPPORTED
PDCAP_WAKE_FROM_D0_SUPPORTED
PDCAP_WAKE_FROM_D2_SUPPORTED

 

Power state mappings:
S0 -> D0
S1 -> D3
S2 -> D3
S3 -> D2
S4 -> D2
S5 -> D3

 

but they should be set to...

Power state mappings:
S0 -> D0
S1 -> D2
S2 -> D2
S3 -> D2
S4 -> D2
S5 -> D3

 

S0..S5 represent increasing levels of System Sleep where S5 = Off and D0..D3 represent increasing levels of Device Sleep

Any idea how to report this as a bug or is posting the issue here sufficient?

Hello, and Welcome to the HP Support Community!

 

This Forum is manned by other users , sitting at home on our couches and trying to help noobs!    Reporting a supposed bug here will likely go unnoticed by HP.

 

Might search Google for "HP bug report website"?
