Yes, but these could be two separate things.  Every time you do a cat
/proc/apm the kernel module queries the BIOS for the power state.
Power_change events are separately sent by the BIOS to the kernel.  In
principle the kernel could be gobbling these up before they get out to
apmd in userland.

I think you have to edit the source directly.  There's an #undef
APM_DEBUG which needs to be changed to #define APM_DEBUG.  You will
get a lot of kernel messages this way, so it's not good for general
use.

But I agree, I think it's likely a BIOS problem.

Good luck!
