FWIW...
I have experienced the same thing on my Dell Inspiron 5100.  I'm not 
currently running it that way, but was. Until I read that ACPI and APM 
will not run together.  Supposedly the last one up notices the first and 
bails.  So I opted for ACPI... which has left me wishing I was back with 
both even though they are not supposed to work together.

I'm interested too, in other's opinions/explanations of this phenomenon.
