The fact that you can only shutdown with pressing the power button is a direct consequence of booting without ACPI, since that's one of the things that ACPI is for, besides FN-buttons, reaction on closing your lid, standby modes and so on. So this is kind of the plan. Hence a more or less modern system is pretty much useless without ACPI. Pretty bad..The second symptom sounds pretty odd, though..
