So increasing the threshold was a good thing (reveal the problem, not hide the problem); As for the cause itself, is there any tool that can be used to at-least gain any info on this? >>From looking at the situation from here with a macbook, the interaction with the battery seems to be the cause, but then on other notebooks it's another situation.(making this problem very intricate). Anyways I don't have a problem changing the threshold or using a boot param, to keep this in somewhat control for the time being until there is a solution. let me know how I can help. regards; -- Justin P.
