--- Comment #7 from Mario Limonciello (AMD) (mario.limoncie...@amd.com) --- > amd_s2idle.py --acpidump Your system doesn't support s2idle at least in the current BIOS configuration. Here are log entries from test script confirming it. 2023-07-22 16:59:22,373 DEBUG: Fetching low power idle bit directly from FADT 2023-07-22 16:59:22,373 ERROR: ❌ ACPI FADT doesn't support Low-power S0 idle 2023-07-22 16:59:22,375 ERROR: ❌ PMC driver `amd_pmc` not loaded 2023-07-22 16:59:22,377 ERROR: ❌ System isn't configured for s2idle in firmware setup 2023-07-22 16:59:22,422 ERROR: ❌ NVME SK hynix is not configured for s2idle in BIOS 2023-07-22 16:59:22,422 ERROR: ❌ NVME SK hynix is not configured for s2idle in BIOS 2023-07-22 16:59:23,185 WARNING: 🚦 The kernel didn't emit a message that low power idle was supported 2023-07-22 16:59:23,185 WARNING: 🚦 AMD-PMC driver is missing 2023-07-22 16:59:23,185 WARNING: 🚦 The system hasn't been configured for Modern Standby in BIOS setup 2023-07-22 16:59:23,185 WARNING: 🚦 SK hynix missing ACPI attributes 2023-07-22 16:59:23,186 WARNING: 🚦 SK hynix missing ACPI attributes > Update: adding s2idle.prefer_microsoft_guid=1 to GRUB_CMDLINE_LINUX_DEFAULT > and setting pm-suspend sleep module to kernel allows Lenovo Legion Pro 5 > 16ARX8 to suspend. This parameter doesn't do anything in the newer kernels and has been dropped. I suggest if you want to use s2idle you need to look for a BIOS setting related to it. Lenovo usually calls it "Sleep Mode" and refers to it as "Windows" or "Windows 10". If you don't have one you won't be able to do hardware s2idle and I suggest you use S3. -- You may reply to this email to add a comment.
