Guter Akku, einfacher Tausch

Der Akku des Asus VivoBooks meiner Frau war defekt. Der Laptop ließ sich nur noch mit Netzteil betreiben. Der Akkutausch war wirklich sehr einfach und erfordert keine großartigen Technikkentnisse. 2 Schraubendreher und 1-2 Plektren sind hilfreich und liegen auch dem Set bei. Beim Entfernen der Schrauben am Laptop am besten ein Foto machen, damit man die Schrauben mit unterschiedlichen Längen hinterher wieder an der richtigen Stelle reindreht. Laptop läuft wieder ohne Probleme. Die Laufzeit entspricht dem Original.
