Can't wake up pc from suspend to sleep

hi.
Since a few weeks, I have an issue with my pc desktop (optiplex 7060) where I can't wake it up from suspend to sleep.

I have to force a shutdown by pressing power button 10s or more. and reboot. If I manually trigger `systemd suspend`, it is fine.

It happens when gnome shell triggers an automatic suspend after 30 minutes.
In fact, it does not happen all the time, and most of the time, it works fine. But at least once a day (so say 1 in 5), it fails.

I can see in the log that it tried to go to sleep.
The last line being "systemd[1]: Starting System Suspend...". I don't know if it failed or not.

The led power is not blinking as expected when I come up later to wake it up; I have switched from zen kernel to vanilla. Changed nothing.

Sometimes fsck is run and had to clean some orphaned inode and stuff like that.

The method to go to sleep is [deep] in /sys/power/mem_sleep

I have added intel_lpss_pci to /etcmkinitcpio.conf MODULES line. Chaged nothing

any idea?
