MBP sehr langsam und schaltet sich ab

Hallo zusammen,

ich arbeite auf einem MBP von 2009, das leider sehr langsam geworden ist. Vor allem beim Laden aufwendigerer Internet-Seiten, inzwischen zB aber auch schon, wenn ich nur in einer Textverarbeitung viele Zeichen schnell lösche und/oder überschreibe.

Außerdem ist natürlich der Akku nicht mehr so doll, die Statusanzeige lautet "bald austauschen". Aber selbst wenn die Anzeige noch bei 20% oder mehr steht, schaltet sich der Rechner manchmal unvorhergesehen ab. Ich kann ihn dann zwar mit ein paar Tastenanschlägen wieder aufwecken, aber das Aufwachen dauert dann mehrere Minuten lang.

Ich hänge mal das EtreCheck-Protokoll von heute an - bestimmt könnt Ihr mehr damit anfangen als ich.. Und vielleicht habt Ihr ja ein paar gute Tipps, was ich tun kann, um die Probleme zu beheben.

Achja, und gibt es Erfahrungswerte, ob bei einem so "alten" Rechner der Akku-Austausch sinnvoll ist?

Schon jetzt vielen Dank und viele Grüße,

Steffi
