Can anyone give me short explanation on whats the difference between
apm and acpi?
Apparently ,I am using apci on my Toshiba laptop but I am getting this error
in my syslog file:


May 12 22:32:11 spark modprobe: FATAL: Error inserting apm (/lib/modules/2.6.3-1-686/kernel/arch/i386/kernel/apm.ko): No such device

Any suggestions or explanations would be appreciated.
