Checking the log files after the next boot told me that cron is waking up the computer and runs a (standard) job at 01:00am every day and then suspends the computer.

I don't think cron is doing this - there are no processes running maybe
some very low level equivalent - like the timer for the wakeup at a
specific time (even though it's disabled)

not in my experience - i can have it suspended for quite a while
but it runs out of batteries in less than a day when suspended via acpi.
(so it's not really suspend)
