Hi, I'm running arch on a new ThinkPad T14s (3Gen Intel). Old school S3 suspend is unusable (kernel panic on resume). In S2idle the battery drain is inconsistent, raniging from 10% to 50% overnight. Seems to be related to the contents of /sys/module/pcie_aspm/parameters/policy (tweaked by laptop-mode-tools) prior to suspend. Particularly, the policies "default" and "powersupersave" correspond to low battery drain, while "performance" and "powersave" prevent PC8 during suspend. Below is an excerpt from S0ixSelftestTool output, full logs for all policies are attached. ---------------------------------------------------------------------------- Available bridge device: 0000:00:06.0 0000:00:07.0 0000:00:07.2 The PCIe bridge link power management state is: 0000:00:06.0 Link is in L1 The link power management state of PCIe bridge: 0000:00:06.0 is not expected. which is expected to be L1.1 or L1.2, or user would run this script again.
