I don't really know how to describe it, but the Fn key effect seems to be always on and I have to press it to undo the effect. It really bothers me because it converts a bunch of keys in the middle into numpad and I don't know any effective solutions right now. Also re-installing the windows is out of the question until I get an external hdd because the hard drive is full.
