What distribution are you using? You may try booting with the kernel argument acpi=off or acpi=force to see if those help. (Some notebooks have buggy acpi that require these)
In Slackware, you have to edit /etc/rc.d/rc.modules to enable APM.
Specifically, uncomment the last line of this section:
Code:
#### APM support ###
# APM is a BIOS specification for saving power using several different
# techniques. This is mostly useful for battery powered laptops.
#/sbin/modprobe apm
If you didn't compile the kernel yourself, then chances are you chose 'bare.i' for the installation and for booting afterwards. 'bare.i' carries only APM support and needs '/sbin/modprobe apm' to be enabled in '/etc'rc.modules' .
The ideal, though, would be to have used 'bareacpi.i' or else recompile your kernel with ACPI support - assuming your hardware supports it, which is the case for almost everything from pIII and over.
