This ACPI shindig was brought into practice around 1996-97 by few industry leaders like HP, Intel, Toshiba and some others. This is for power management (Advanced Configuration and Power Interface) of current generation boxes. Many boxes have broken ACPI implimentations, or they get broken with change of h/w like addition of RAM which increases the power requirements from the preset values. In theory, a change of power status may break the built-in h/w ACPI configurations. I think the current specs (Ver 3.0) addresses the issue, though I am not very sure. This seems to be the likely explanation to me ... any hardware gurus around to correct the above assumptions ? Bish
