Hello Ged, Thanks for the informative message!
Unfortunately, since I'm using ACPI which (by my humble understanding) is mutually exclusive to APM, I believe none of those APM settings make any difference to me? (I have all APM turned off, as I thought ACPI was completely different than APM; Toshiba APM support is broken, I have to use ACPI).
