This is my first tutorial and first screen replacement on this laptop, the model type of the computer is 3460. the screen part number is 04Y2061 (without the wwan ant.), the screen with the wwan antenna is 04Y2060.
Other option to replace the screen as it was suggested by a user:
you dont need any tools at all a finger nail pushed into the top edge and worked round the gap allows the bezel to come off very easily. The screen itself has no screws attaching it to the lid you simply lift it up from the top end of the lid remove the connector at the bottom put the new screen in put the connector back and replace the bezel.
