searched
http://www.linuxquestions.org and tryed out these:
root:# modprobe apm
FATAL: Error inserting apm (/lib/modules/2.6.22.14/kernel/arch/i386/kernel/apm.ko): No such device
also people there quite frequently asked for outputs of "ps aux | grep acpi" and "ps aux | grep apm", so I'll include them here, too.
root:# ps aux | grep acpi
root 3971 0.0 0.5 2004 636 pts/0 R+ 22:38 0:00 grep acpi
root:# ps aux | grep apm
root 3973 0.0 0.5 2004 640 pts/0 R+ 22:39 0:00 grep apm
and also
root:# ps aux | grep apmd
root 4050 0.0 0.5 2004 636 pts/0 R+ 23:00 0:00 grep apmd
root:# ps aux | grep acpid
root 4052 0.0 0.5 2008 640 pts/0 R+ 23:00 0:00 grep acpid
also I am thinking about kernel and/or bios upgrade, if it could help.
one more thing:
in bios I turned off bios power management, because I have read it helped someone with similar problem. still have no result.
