Could prove the purchase with the bank statement, but there's only the dealer and the final amount on it and not the purchased goods.
It is a power supply unit that also burned the laptop's charging socket. Of course I would have gladly reimbursed the repair costs. I bought the power supply at the end of January, so it happened within the legal six months, so a deficiency must already be assumed when buying.
Well.
Strictly speaking, the receipt / invoice is not necessary to assert your statutory warranty claims.
Then there's a witness, the entry in their cash register system or simply an account statement.
But, being right and getting right…
If you e.g. Bought from a branch, you can't even prove that you just bought THERE.
If you no longer have a receipt, the guarantee is in the bucket. This is the lesson to be paid. It is up to the dealer to decide whether to grant goodwill. Most of the time, they are very accommodating because every five minutes of discussions with people who provide their bank statements are too expensive and waste time that could be spent on more important things.
The so-called "warranty" does not extend to consequential damage to third-party products. If the power supply itself is not broken at all, you won't get anywhere with the "warranty" anyway. So you have to prove in the first 6 months at the request of the dealer that the part is broken at all. The damage to the connected device may well have arisen because the connected device itself is broken.
But even then, the "warranty" only covers the defect in the power supply and not in the connected device. The manufacturer or importer of the power supply could then be considered as part of its product liability. Here, however, the requirements are significantly higher than with the "warranty".
