Power Management with APMD

I am running Mandrake 7.1 on my machine ( AMD Athalon 650 +128M+30G )

I am also running apmd with what ever standard configuration provided in /etc/sysconfig/apmd I have also enabled my BIOS power management settings

I have noticed that after about 20 mins of idle time my machine goes into standby but it wakes up when I do something like moving the mouse or pressing any key.

But recently I had noticed that if I leave it idle for a longer time even the power LED goes out and I cannot revive it by any of the above methods . ( though the CD drives work fine and I can here the fans inside )

I had to reboot my machine. after it started up I noticed the following line in /var/log/messages

>Jul 21 09:50:10 hobbes apmd[360]: System Suspend

What is happening here ? is there a proper way to revive it from its deep slumber (with our rebooting) and should I be concerned about any hardware or settings fault. ? I don't have windows on my machine so I have no way of checking if I am alright otherwise!

Any comments will be appreciated ..

My motherboard manual briefly describes my BIOS APM settings, it talks about the Suspend timeout settings and boot up based on the network card access. but nothing about waking from suspend without booting up again.

All I wanted was to have some way the system goes into some sort of low power mode after some specified period of inactivity . Since I am running linux I wanted to keep it up 24x7 and hopefully access it over the network.

yesterday I had tried using kapm a applet interface to apm . I could not wake the system up after intentionally suspending it through that either.

I will still do some exploring and see if I can figure out anything useful.

Thanks again
