CPU monte en flèche et surchauffe sur une 18.04

Bonjour, j'ai un problème sur une machine nouvelle achetée où j'ai installé Ubuntu 18.04. En effet, la moindre action fait monter le CPU de manière très importante (par exemple, la navigation dans Chrome/Firefox, le changement d'espace de travail, ...)

Tout d'abord, voici quelques informations sur ma machine:

J'ai soupconné des problèmes avec les pilotes de ma carte graphique, j'ai donc mis à jour les pilotes:

Je sais plus trop quoi faire ou tester, si vous avez des pistes je suis preneur. N'hésitez pas à me demander plus de précisions, je suis pas expert donc je ferais mon maximum pour vous fournir ce dont vous avez besoin.

Re : CPU monte en flèche et surchauffe sur une 18.04

Salut jouby,

Tu peux essayer de déterminer quel processus consomme autant de CPU au moment où ça arrive, cela te permettra de trouver une piste assez concrète sur le problème.
Pour cela utilise la commande suivante, par défaut, les processus sont listés en fonction de leur consommation en CPU.

Je reviens vers toi.

Re : CPU monte en flèche et surchauffe sur une 18.04

Salut DarkBahhh,

Alors le truc c'est que ça dépend de l'action effectuée. Si je navigue sur Chrome (chargement d'une page, changement d'onglet, scroll sur une page) , ca sera le processus de chrome qui monte en flèche. Si je switch plusieurs fois de bureau, ca sera gnome-shell. Si j'utilise firefox, ca sera firefox etc etc

Je ne suis pas arrivé à identifier un processus en particulier qui poserait problème.

Re : CPU monte en flèche et surchauffe sur une 18.04

Salut,

D'après les logs fournies (dmesg), le problème est que ta CPU surchauffe. Tu peux le vérifier en ayant installé lm-sensors et en lisant cette documentation.

Si ce PC est sous garantie, après vérification des T°, il faudra probablement le retourner au fabricant.
Si le PC n'est plus sous garantie, il faudra le démonter ou le faire démonter pour changer la pâte thermique de la CPU.

A+


Un problème résolu ? Indiquez le en modifiant le titre du sujet.

Re : CPU monte en flèche et surchauffe sur une 18.04

J'ai contacté le fabricant, je vais renvoyer le PC. Y-en a pour 2 à 3 semaines, on verra bien ce qu'ils disent. Je vous tiendrais au courant.

Merci pour vos retours.
