And comes down ...

Samsung France no longer refers to this product on its support site. He probably wants to hear about.
I expect myself to be returned after repair parts (LCD fucked and damaged hard drive) to determine what really happened but one thing is sure: it exploded in flight, all alone and I 350 euros in my pocket. The computer suffers impact. Except he traveled by train in a cover itself in a padded bag and placed on the seat next. I am more than suspicious.
Especially since the failure has been slow: first a black spot the size of a piece of 10 cts and cracks and other stains and only then freeze a system increasingly long.
And each time, the situation deteriorated following the opening and closing the cover (which rather makes me suspect a problem in the relationship: I have the same problems with my shower door and it p ... flow seal that does not take up one day my door glass will explode in rain).

When the Samsung support, there are only the No. Telephone worthwhile (operators are friendly, attentive and knowledgeable). For cons, the chat is never open and the contact form is intended only to waste your time (probably a robot with a phony name Claude SALOMON kind that redirects you, or rather invites you to dem ** * alone, on the phone #).

I put a bad score for several reasons:
- Windows 8 is rotten
- The robot to waste time
- Suspicion: the computer which disappears showcases (amazon, fnac etc.) after dying suddenly after two months.

Eventually the answer:

The computer came back repaired and I could watch the parts.
The hard drive is in perfect condition and did not deserve to be replaced (except to consider that windows 8 is either a sign of failure).
The screen is actually striped like he is twisted which makes me doubt the fact that the shock is outside. Rather, it is what happens when you force closing the cover when we left a USB stick between the hood and the slab ... I will have a chat with my daughter.
I keep my note to WTF as it was perfectly useless to replace the hard drive (I have saved 100). Samsung has only audit partners (repair shop) to find they put the thumb on the scale.
