Had this annoying problem in my linux Xubuntu 20.04 when putting on suspend the system then starts even though I put it in suspend and sleep. Using acpitool to turn off wake-up from unnecessary devices. But the problem the change is not permanent and does not survive a restart. So I used cron @reboot to make sure it is always off: @reboot acpitool -W 3 && acpitool -W 9 && acpitool -W 10 && acpitool -W 17 && acpitool -W 63 && acpitool -W 64 && acpitool -W 66 && acpitool -W 68 && acpitool -W 74
Points regarding computing that I always forget - so I write them here to find them easily and maybe other could benefit too.
