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;
