Subject: Lenovo P1 suspend to ram regression

Dear all,

(please Cc, thanks)

since some time, probably some kernel revisions, my Lenovo P1 Gen6
goes to sleep (suspend to ram), but produces considerable heat even
in sleep mode. Not surprising, it also drops battery level within
short time.

I am not sure where to report this bug, as well as which information I
can provide. 

Kernel is 6.15.4-zen2-1-zen on Arch Linux

>From the dmesg:

[    0.000000] DMI: LENOVO 21FV002EUS/21FV002EUS, BIOS N3ZET48W (1.35 ) 02/25/2025

The supported sleep state seems to only be s2sleep:

❯ cat /sys/power/mem_sleep
[s2idle]

What other information can I provide to debug this issue.

Thanks for any pointer, and please Cc.
