If a private person offers and writes an article on ebay as new, there's still a 1 year guarantee…

In the v.e. Case is about a laptop, it is optically really like new. Unfortunately, he only switched on once, since then he can no longer be switched on, the charger "ticks" when charging…

The seller claims that he sent the Läppi in perfect condition, before that even a "specialist" checked and reset it…

VK says: Since he once (!) Got involved with us, he is now out of it all, and he also accuses us of having broken it, maybe we dropped it? Or emptied liquid over it? - we're accused…

The package did not include an invoice to enforce the warranty claims.

What are our rights in the case? Is he bound by the guarantee offered? Does he have to take the device back and transfer the money back?

Payment was made via PayPal. Ebay buyer protection is activated.

If the part were a private sale to the exclusion of liability for defects, then the seller would be clean - device arrived and went first.

However, since here as a guaranteed property "one year guarantee" was probably also sold, and the lack of proof of purchase was not delivered, I would start right there.
