So i have the Dv4, just purchased September 4th. I think that this update is the cause of my sudden emotions to throw my laptop out of the window sometimes. (like in the middle of a huge research paper D=) but i did the first step and I was unable to find the correct update number, it seemed like I had every single one except that one....are there other updates that may have had the same effect like this one? Any suggestions for me? Thanks
