I've using my lenovo laptop for almost a year but lately i've noticed a small line on my screen , I connected it with my tv via HDMI and the line wasn't there , I did a printscreen and the wasn't there.
I tried to upload my graphic cards and nothing has changed .
Here is the problem :

lol... that irritates! Hope you are using windows 8. If you close that windows explorer, did you still see it. If you open any other thing such as, browsers, words file, etc.. is that little thing on the screen, if so, that could be hardware issue, I mean the screen it self.

If you open any other thing such as, browsers, words file, etc.. if that little thing is not on the screen, then try to change the view setting, such as 'Details, Tiles, Contents...etc'.
