The ACPI method for the Toshiba is not the same as for the Dell. Toshiba use \_SB_.VALD.GHCI() method in order to access the HCI whereas Dell use \SMI() (and other methods).

Depend. If APM work better for you there is no reason to enable ACPI after all. Cheers, -- Bruno Ducrot -- Which is worse: ignorance or apathy? -- Don't know. Don't care.
