Hi,

I am using my laptop and want to config power manegment system to sleep
down my computer when its battery is running low.

I found there are two packages, APM and ACPI, both can do the job and
both got installed in my slackware. To save my learning time, I want to
get know from your experts, that what package is the standard or
perferable tool to do the job?

Thanks in advance.

It depends on your BIOS, so on your _specific_ laptop.
APM (Automatic Power Manament) is the older tool, quite reliable
but a bit less powerful, ACPI (Advanced Configuration and Power
Interface) is more recent and powerful, but doesn't work with BIOS'es
that don't support that interface.
Normally you should try ACPI first, and only if it doesn't work
reliable, you have to disable it in the bootloader (acpi=off and
arguments like that) and startup the APM daemon instead (APM will
NOT work when the kernel already initialized ACPI).

Thanks for the tips.  So I think I will try acpi, since my running of
'acpi -B' get good results.
