Dear coreboot folks,
the proprietary BIOS allows to disable/mute sound, when battery status
is low or the power cable is plugged in or out.
Is it possible to configure that with coreboot or ectool [1]?
src/ec/lenovo/h8 $ tail -9 h8.h
#define H8_EVENT_BAT0 0x4a
#define H8_EVENT_BAT0_STATE 0x4b
#define H8_EVENT_BAT1 0x4c
#define H8_EVENT_BAT1_STATE 0x4d
#define H8_EVENT_FN_F5 0x64
#define H8_EVENT_FN_F6 0x65
#endif
src/mainboard/lenovo/t60 $ git grep -i mute
acpi/platform.asl: \_SB.PCI0.LPCB.EC.MUTE(1)
Thanks,
Paul
