I recommend to use default settings. By disabling ACPI you'll only cripple many internal hardware functions of your laptop.So if you have the latest version of debian and it is logging on and off ok , what are the acpi setting, kernel parameters.
You can find this out by pressing 'e' when the grub screen is showing.
I should have taken note when I had debian installed.
