Hola, ultimamente sto testando questo interessante progetto, YogaSMC L'ho provato prima su un Lenovo Ideapad 330s (i7 8550u), perché ero interessato alla Conservation Mode, che permette di bloccare la carica della batteria intorno al 60%, preservandone la salute. Non avendo riscontrato alcun problema con questo dispositivo, passo al più recente Ideapad s540 (i5 10210u), e qui sono sorti i problemi. Sebbene non faccia fatica a controllare la backlight della tastiera e la modalità di gestione delle ventole (tramite DYTC), purtroppo la Conservation Mode non funziona in alcun modo Andando ad analizzare i logs.zip ad esempio con log stream --predicate 'processID=0 && (senderImagePath contains "YogaSMC" OR senderImagePath contains "ACPI")' si nota che c'è un problema con POWS, che non riesce a trovare il metodo \_SB.PCI0.LPCB.EC0._Q37 2020-10-19 12:23:02.280493+0200 0x193 Default 0x0 0 0 kernel: (YogaSMC) YSMC - Info: IdeaVPC::VPC0 ReadEC timeout 0x10 2020-10-19 12:23:02.280526+0200 0x193 Default 0x0 0 0 kernel: (YogaSMC) YSMC - Info: IdeaVPC::VPC0 Failed to read VPC 38 2020-10-19 12:23:03.282571+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) ACPI Error: 2020-10-19 12:23:03.282581+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) ACPI Error: 2020-10-19 12:23:03.282594+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) [POWS] 2020-10-19 12:23:03.282596+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) [POWS] 2020-10-19 12:23:03.282599+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) Namespace lookup failure, AE_NOT_FOUND 2020-10-19 12:23:03.282601+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) Namespace lookup failure, AE_NOT_FOUND 2020-10-19 12:23:03.282607+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) (20160930/psargs-463) 2020-10-19 12:23:03.282608+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) (20160930/psargs-463) 2020-10-19 12:23:03.282617+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) [_Q37] @0003C #002D: 2020-10-19 12:23:03.282619+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) [_Q37] @0003C #002D: 2020-10-19 12:23:03.282622+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) A 2020-10-19 12:23:03.282623+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) A 2020-10-19 12:23:03.282625+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) D 2020-10-19 12:23:03.282625+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) D 2020-10-19 12:23:03.282628+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) P 2020-10-19 12:23:03.282628+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) P 2020-10-19 12:23:03.282630+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) T 2020-10-19 12:23:03.282631+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) T 2020-10-19 12:23:03.282633+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) 2020-10-19 12:23:03.282634+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) 2020-10-19 12:23:03.282637+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) No Local Variables are initialized for method [_Q37] 2020-10-19 12:23:03.282639+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) No Local Variables are initialized for method [_Q37] 2020-10-19 12:23:03.282643+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) 2020-10-19 12:23:03.282644+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) 2020-10-19 12:23:03.282647+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) No Arguments are initialized for method [_Q37] 2020-10-19 12:23:03.282648+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) No Arguments are initialized for method [_Q37] 2020-10-19 12:23:03.282652+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) 2020-10-19 12:23:03.282653+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) 2020-10-19 12:23:03.282656+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) ACPI Error: 2020-10-19 12:23:03.282658+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) ACPI Error: 2020-10-19 12:23:03.282661+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) Method parse/execution failed 2020-10-19 12:23:03.282663+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) Method parse/execution failed 2020-10-19 12:23:03.282668+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) [\_SB.PCI0.LPCB.EC0._Q37] (Node ffffff803cd692a0) 2020-10-19 12:23:03.282670+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) [\_SB.PCI0.LPCB.EC0._Q37] (Node ffffff803cd692a0) 2020-10-19 12:23:03.282674+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) , AE_NOT_FOUND 2020-10-19 12:23:03.282675+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) , AE_NOT_FOUND 2020-10-19 12:23:03.282679+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) (20160930/psparse-632) 2020-10-19 12:23:03.282679+0200 0x190 Default 0x0 0 0 kernel: (AppleACPIPlatform) (20160930/psparse-632) Inoltre, si notano diversi problemi del tipo: kernel: (AppleSMCLMU) AppleLMUController::smcReadKey Error: received error 0x84 when reading key 'MSLD' kernel: (AppleSMCLMU) AppleLMUController::smcReadKey Error: received error 0x84 when reading key 'ALV0' Il fatto è che MSLD ed ALV0 non compaiono nelle mie ACPI. Allego ACPI ed EFI e vi chiedo aiuto per fare un po' di chiarezza sulla questione. Thanks in advance EFI + ACPI.zip
