dmesg

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

dmesg with rst

I read somewhere that intel raid could have an impact, so here is the dmesg with intel raid enabled (like it was actually last night)
