one question about ACPI

hi, I installed archlinux on my macbook 2013 late, and I found dmesg | grep ACPI,  outputs is ACPI: (supports S0 S4 S5), does that means that my laptop does not support S3 (deep mode), or any other change or config for my macbook that could open this S3 option? thanks a lot

Re: one question about ACPI

That is the *only* ACPI line in your dmesg???

freeze standby mem disk
cat /sys/power/mem_sleep

Shallow sleep is btw S0iX, you can try passing "mem_sleep_default=deep" to enforce S3 sleep (you can also write into /sys/power/mem_sleep at runtime)

To figure whether the system properly S3's, just try to "systemctl suspend"…

For the future please pick more meaningful and less generic subjects.
