nothing special. I have syslog monitored at tty11: just portslave/pppd
activity of modem users and rare cron lines about my python tasks.
Nothing about APM or so... There is even NO "APM" WORD found by grep in
/var/log! I think it is something different. Maybe next reboot I'll
check BIOS settings again.

yes, deeply in the morning, when all night users went to their beds and
when day users are still sleeping. Approx 2-3 hours of dialup and network
idle, but cron awakes with python tasks every minute for different purposes.

It doesn't go away. I have set up crontab to ping leased client with 5
small packets every 10 minutes... Guess what? It didn't help... :(

As I have recently checked my 'make menuconfig' infos on 'APM' subject...
It is off. And there is no visible reason for my PC to sleep, but ping
from outside disappears after 1 hour or more of idle.
P.S. What next? :-\ I will check BIOS setting upon next reboot.
