[MacBook Pro] Kernel Panic, Lüfter und schwarzer Bildschirm

[Nosh]

Moin,

ich bekommen seit einiger Zeit auf meinem Macbook Pro Kernel Panics (siehe unten). Diese gab es ca 2-3 mal am Tag, tageweise aber auch gar nicht. Ich habe die Festplatte gecheckt (alles OK) und Ram (auch).


Mir war generell aufgefallen, dass der Lüfter fast immer läuft.


Vor 5 Minuten kam es dann zum Supergau: Lüfter wird lauter und plötzlich schaltet sich der Computer komplett aus (ohne Kernel Panic). Das Macbook liess sich auch nicht mehr anschalten.

Schweissgbadet habe ich es nochmal versucht, mit Pram-Reset, und siehe da, es funktioniert. Der Lüfter ist gar nicht mehr zu hören.


Nun meine Frage: Weiss jemand woran dies liegt ? Ist dies damit gelöst, oder steht der Supergau vor der Tür ? Vielen Dank schon mal.

Der Bericht ist unspezifisch, d.h. es lässt sich keine genaue Fehlerquelle ablesen.

In fast allen Fällen heißt das leider, dass kein Software-Fehler, sondern ein schwer zu findender Hardware-Fehler vorliegt.

Oha, ich hab´s schon befürchtet. Anbei nochmal ein neuer:

Hi,

was sagt istat ? Ist es berechtigt, daß die Lüfter hochdrehen? ist die cpu / gnu tatsächlich zu heiß?

Einfach ausgehen wenns zu heiß wird ist ein Schutzmechanismus! Auch ohne Panic...
Apple Diagnosis ? Spannungsschwankungen in der Stromversorgung?

 

[Nosh]

Wenn der Computer ausgeht mit schwarzem Bildschirm ist das auch Schutz?

Momentan habe ich 59º - 70º.
Spannungsschwankungen schliesse ich aus

Hast Du jetzt schon mal die Hardwaretests durchgeführt? Taste D auf der Notebooktastatur beim Einschalten drücken und gedrückt lassen.

Die einfachste (und statistisch vermutlich häufigste) Fehlerursache: kaputter RAM.

 

[Nosh]

Ja, "leider" sagt der Hardwaretest das alles in Butter ist. Leider sagen die schwarzen Bildschirme etwas anderes...

externe Festplatte mit sauberem OS X booten - und keinerlei Backup oder Software installieren. Stürzt das System auch damit ab, Apple auf den Tisch knallen, wenn Garantie vorhanden ist. Alleine schon für diese entspannende Möglichkeit bezahle ich gerne die Garantieerweiterung.

Ständig laufender Lüfter kann auf defekte Sensoren und/oder Akku hindeuten, vielleicht ist der Lüfter aber auch hinüber.
