After only a few weeks of use, the product began to do light up sporadically then one day ... at all. This product is under warranty it was shipped for service ACER. A week later, the service contacts us asking the administrator password. But never administrator password has been entered ... what we explain to the telephone counselor, without of course being able to provide proof. ACER his side can not prove that the faulty computer would not have generated password. Why this maneuver in ACER? Well, you should know that in all ACER updating of "software" is billed, as well as the warranty does not cover software failures HDD !!! Thus, in asking the client a request that they can not honor, ACER This ensures a cash inflow 1 / you pay (60 euros) the fanciful "word search going on," 2/3 they diagnose the fault / prétexteront they undoubtedly a purely software failure (not after the components) which will also be your responsibility. Well done !! ACER AMAZON has reacted immediately contacted and offered two solutions refund or replacement product. Without hesitation, we opted for repayment and it was very fast.
