Thanks to YouTube The installation is very simple, you only need a Phillips precision mechanic, a small flat-head screwdriver (or knives) and a plastic card to open the housing and already everyone can build with reasonably fine motor skills this part.
The delivery was fairly quick (a few days), the package in a thick cardboard envelope I found a little adventurous, but the spare part works fine.
When installing you should bring the screws in the original holes, as they are of different lengths.
Although one wonders what is broken in this part, but on the other hand, it is also nice to be so simple it can repair itself. My battery lasts anyway yet, so I did not have to replace him.
Repairing makes in any case more fun than buy new, here you can still be a real hero of the family :)
