Sorry, I read the guidelines after posting. My flicker starts everytime the processor hits around 45°C and doesn't stop until the SP coools down. The problem is that this is my primary work device and because of the awful thermals my regular work session manages to heat the tablet beyond filckering temperature after 3 hours. I have the SP4 with a Core I7 with 8 gigs of RAM and 256 gigs of HDD space and a type cover that is starting to fall apart just from typing (all the cloth corners begun to tear) Needless to say I payed a hefty price for this piece of junk
