I have been running sleep studies to try to diagnose why this laptop is consuming more power than expected while asleep, and have narrowed it down to the secondary NVMe SSD I added. The sleep study reports that with the secondary SSD inserted, the system never enters a low power HW state:
And the power consumption increases 3-4x. Looking through the details puts the culprit as the “SOC Subsystems,” which can be expanded to blame the PCIe root port:
Is there any setting I can try to get the system to properly sleep (get the HW to >90% low power time)? Or is this a limitation of the particular SSD that could be resolved by buying a different model? Or am I SOL and there’s nothing to do other than take out the SSD?
