are you still able to use the machine? In the vaio control manager did you keep your battery charge at 80% or go all the way to 100%? Also did you keep your canvas on high power the entire time you had it as well as use it for intensive tasks that raised the temp like adobe Photoshop work or any programs that were intensive? Sorry to hear about the problem, let us know how contacting vaio went. It seems to be a recurring problem that has cropped up countless times on this forum.
