I've never found them useful. If it's second hand and not working right, a factory reset should take it back to the beginning and it will work unless there is pilot or a hardware error.
I have a Fujitsu Lifebook U laptop. i bought it second hand and the camera, in Skype and in another photographing program doesn't work well. the background is completely blue and i can hardly see myself. dominant blue.
How can I attach the dxdiag results here? i can't find the select file button
