Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer
to resume working quickly. Very few platforms support the S1 or S2 Sleep states.

Hi,
What is the symptom of the issue you encountered? The report shows there's a "known incompatibility with the hardware" and all "USB Suspend:USB Device not Entering Suspend" errors are caused by the prevention of Power Management (which is disabled due to
hardware issue) so have you made any hardware change rencently?
You can also manually check the Power Management setting, control panel\power options\chang plan settings\change advanced power settings, scroll down to PCI Express （check if you can set it to "Moderate Power Savings") and Process Power Management(should be
active).
