SleepStudy
Manually put your computer into sleep for at least 10 minutes. Then generate a sleep report using powercfg /sleepstudy
and view at sleepstudy-report.html
.
Find the last few entries with a title System Power State: Modern Standby
. If DRIPS is available, there will be a DRIPS Histogram
followed by some diagnostic data.
If your computer is S0ix enabled and enters S0ix mode successfully, STATE
will be Modern Standby
. The entry's color will be either red, yellow, green or grey depending on how fast the battery is drained. (Grey means charging.)
If DRIPS is enabled, % LOW POWER STATE TIME
will have 2 columns (SW
and HW
) instead of one (SW
only). Both cases are shown on the screenshot above. Differences between SW
and HW
see DRIPS.

Name(DEVY, Package()
{

Package() {"\\_SB.PCI0.RP02", 0x0, /* ... */ }

- If you have virtual network interfaces (VMWare VMnetN, etc.) and they are shown as connected, no IP configured and no DHCP leases acquired, this can happen. Allocate static IPs for them, disable IP stacks or simply disable them.
- Your NIC might not have DHCP offload capabilities.
