Bonjour à tous,

J'ai le souci suivant : mon iMac (8,1, Intel Core 2 Duo, 2,8GHz, 24"), se met en veille tout seul, mais toujours à des moments précis. La nuit, je le met en "suspension d'activité", quand je le ré-active le matin, environ 1/4 d'heure après, il se met en veille tout seul, juste une seconde, puis se rallume quelques secondes, puis se remet en veille... etc. pendant quelques minutes, ca dépends des fois.

J'ai bien fouillé les forums et autres, j'ai vu plusieurs autres personnes ayant des soucis un peu similaire, j'ai essayé plusieurs "trucs" qui ont marché avec d'autres, mais chez moi, rien...
Ca fait 2 mois environ que j'ai ce souci.
Passé cette période, il fonctionne normalement tout le reste de la journée, mais bon, dès que je suspend l'activité, ou l'éteint, j'ai le souci 1/4 d'heure après.


Je me permet de copier/coller ci-dessous un bout d'historique du SystemLog, des quelques minutes pendant lesquelles il m'a fait ça ce matin, si jamais ça parle à quelqu'un...
(une version complete des quelques minutes ou il y a eu le souci est visible ici : http://test.atelier36.net/rezo/histo.txt

J'avoue que certains matins, quand il me fait ça alors que je sus en train de travailler et que je suis à la bourre et pas tout a fait réveillé, j'ai envie de le jeter par la fenêtre... :rateau:

Donc merci d'avance pour toute aide ou pistes pour régler le souci :)

David

Comme ça, intuitivement, je dirais que c'est un problème d'alimentation. C'est le message "Sleep: Success - AC - Low Power Sleep" qui m'y conduit.
Dans la mesure où c'est un iMac, il n'a pas de batterie : une situation de "Low Power" est donc due à une alimentation défaillante [ou vue comme telle par le système].

Mais je ne sais pas comment tester la chose sans aller au SAV.
