[ISSUE]
I have a dual boot acer helios laptop (windows is on the nvme, ubuntu on
an SSD). Once I boot into Ubuntu (SSD) my drive works as expected.
But once I set my laptop to sleep and wake it back up again the nvme
drive power state is set to max rather than the default low power state.
This causes a lot of heat to be generated and the smartctl tool reports
the tempSenor#2 as 80-90C when in low power mode it runs at 40-60C.
I've observed this behaviour under Ubuntu 20.04.6 LTS and via live USB
(22.04.3 LTS, 23.10)
BEFORE SLEEP:
sudo nvme get-feature /dev/nvme0n1p1 -f 2 -H
get-feature:0x2 (Power Management), Current value:0x000004
Workload Hint (WH): 0 - No Workload
Power State (PS): 4
AFTER SLEEP:
sudo nvme get-feature /dev/nvme0n1p1 -f 2 -H
get-feature:0x2 (Power Management), Current value:00000000
Workload Hint (WH): 0 - No Workload
Power State (PS): 0
[Fix]
If i run the following command i can manually set the drive into a low
power mode which dramatically effects both the onboard nvme temps and
system temp (PCH chip)
sudo nvme set-feature /dev/nvme0n1p1 -f 2 -v 4
