Hello,
I've a Dell 5530 (DMI: Dell Inc. Latitude 5530/0C6CYC, BIOS 1.18.0 11/08/2023)
with the S3 block mode in the bios disabled, but it seems that linux is not
seeing the S3 mode:
# journalctl -b|grep ACPI|grep 'PM: (support'
fév 16 10:01:48 eriador kernel: ACPI: PM: (supports S0 S4 S5)
# cat /sys/power/mem_sleep
[s2idle]
This wouldn't be a big problem is the battery drain was not that terrible (~50%
overnight in sleep)
So the question is:
* Should the S3 mode be available?
* What is causing a so big drain?
# uname -a
Linux eriador 6.6.15-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.6.15-2 (2024-02-04)
x86_64 GNU/Linux
