Surchauffe du PC: problème logiciel?

Support Debian
#1

Bonjour à tous, j’ai un problème sur mon Thinkpad X60 qui tourne sous Crunchbang Wheezy. Ce Thinkpad a un BIOS Coreboot, et, bizarrement, lorsque je veux rédiger un message pour un forum de discussion comme celui-ci, le ventilateur se met à tourner à la vitesse maximum, la température du CPU augmente à toute vitesse, et la machine finit par s’éteindre.
Le phénomène est moins apparent lorsque je veux regarder une vidéo sur Youtube.
Bien sûr, j’ai pris les mesures habituelles: démontage de la machine, dépoussiérage soigneux, et changement de pâte thermique, avec un résultat mitigé.
J’ai remis à jour le BIOS, ce qui a eu des effets assez spectaculaires car la température a chuté de 25° au moins. Mais malheureusement le phénomène est revenu au bout de quelques mois.
Est-il possible qu’il s’agisse d’un problème logiciel? La commande Top me montre que ce qui prend le plus de ressources, c’est Xorg, et Chromium lorsqu’il tourne.
Merci d’avance pour vos idées!

[edit] je donne le noyau: Linux debian 3.2.0-4-686-pae #1 SMP Debian 3.2.65-1+deb7u1 i686 GNU/Linux

Bonjour

regarde du coté de flash player.

Plus ca va plus il devient gourmand en ressource

As tu essayé avec un autre navigateur?

#3

Salut Minus,

Oui, j’avais regardé. J’utilise pepperflashplugin-nonfree. Mais je ne vois pas trop ce que je peux faire s’il consomme trop de ressources. Y a-t-il une alternative?

Pas de différence avec un autre navigateur.

Bon, heureusement qu’il y a cette discussion: installer-flash-pour-grand-nouveau-venu-t51227.html

J’ai remplacé pepperflash-plugin par browser-plugin-lightspark.

Verdict: un léger mieux, le ventilo s’emballe moins vite et la température du CPU se stabilise aux alentours de 86° pendant que je rédige ce message. Ce n’est quand même pas glorieux.

Xorg et chromium consomment la majorité des ressources, mais changer de navigateur n’apporte pas d’amélioration.

Bonjour Minerve.

Sur mon ordi:
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03)

J’avais déja vu que mon ordi semblait ramer un peu (beaucoup) en éditant un message, et entendu le ventilo à chaque coup.
Je n’avais jamais porté attention au pourcentage de mon CPU (environ 60%).

Je pencherai pour les Smileys sur ta gauche (en éditant un message), ou ci dessous, comme très gourmand en ressources.

:slightly_smiling: :laughing: :smiley: 8) :open_mouth: :angry: :stuck_out_tongue: :unamused: :blush: :confused: :wink: :007 :005 :arrow_right: :083 :smiling_imp: :115 :119 :mrgreen: :013 :016 :12 :118 :023 :049 :018 :033 :030 :017 :041 :108 :008 :079 :075 :114 :078 :119

Fait un test fenêtre réduite.
Fait un test sur d’autre sites avec des émoticônes.

Ton ordi devrait normalement pouvoir tenir 100% des ressources CPU, sans atteindre sa limite de température, même en plein été.
=> Problème matériel

La majorité des processeurs actuel sont suffisamment puissants pour que même du “mauvais code” passe assez facilement, ce qui n’encourage pas certain développeur à optimiser leur code.
=> Problèmes logiciels

Peut être qu’il manque à nos processeurs un jeu d’instructions, pour que certains logiciels s’exécutent correctement?

#7

J’ai l’impression que sous Linux la gestion ACPI merde un peu…mais peut être est ce qu’une impression…

ps: il me semble que normalement c’est le sous le BIOS que s’effectue cette gestion mais bon je me fourvoie peut être

#8

J’ai telechargé un émoticône du forum, ce sont des gifs 15x15.

Suite à une rapide recherche google:
http://mikedafunk.over-blog.org/article-desactiver-les-gifs-animes-pour-gagner-en-ressources-autonomie-77321686.html

=> Solution: Désactiver les gifs animés dans Iceweasel. (Pour Chromium c’est à voir)
about:config
Changer la valeur de la ligne “image.animation_mode” de “normal” à “none”.

J’ai fait le test => plus de ventilateur, CPU à 4% en éditant ce message au lieu des 60% habituel.

#9

Très intéressant, merci! Je viens d’essayer ça. Tout ce que j’ai trouvé pour désactiver les animations Gif, c’est d’installer une extension supplémentaire dans Chromium. Si quelqu’un a une méthode plus “propre”, ça m’intéresse (je cherche encore).

Bien joué, j’ai un PC portable un peu daté qui te remercie !

[quote=“minerve”]Bonjour à tous, j’ai un problème sur mon Thinkpad X60 qui tourne sous Crunchbang Wheezy. Ce Thinkpad a un BIOS Coreboot, et, bizarrement, lorsque je veux rédiger un message pour un forum de discussion comme celui-ci, le ventilateur se met à tourner à la vitesse maximum, la température du CPU augmente à toute vitesse, et la machine finit par s’éteindre.
Le phénomène est moins apparent lorsque je veux regarder une vidéo sur Youtube.
Bien sûr, j’ai pris les mesures habituelles: démontage de la machine, dépoussiérage soigneux, et changement de pâte thermique, avec un résultat mitigé.
J’ai remis à jour le BIOS, ce qui a eu des effets assez spectaculaires car la température a chuté de 25° au moins. Mais malheureusement le phénomène est revenu au bout de quelques mois.
Est-il possible qu’il s’agisse d’un problème logiciel? La commande Top me montre que ce qui prend le plus de ressources, c’est Xorg, et Chromium lorsqu’il tourne.
Merci d’avance pour vos idées!

[edit] je donne le noyau: Linux debian 3.2.0-4-686-pae #1 SMP Debian 3.2.65-1+deb7u1 i686 GNU/Linux[/quote]

Je commencerais par installer un noyau plus récent (depuis les backports) pour voir si cela améliore la gestion de l’énergie, ainsi qu’un outil de diagnostic comme powertop.

J’ai installé un kernel plus récent: 3.16.0-0.bpo.4-686-pae. Bof. J’ai même l’impression que c’est pire.

Ce qui est curieux, c’est que la température du CPU peut grimper même lorsque ce dernier n’est pas surchargé (p ex entre 5 et 10%).

#13

Tu as laptop-mode-tools installé?

#14

Non. Mais c’est pour la batterie, ça?

Je n’ai plus de batterie, elle a lâché sans crier gare il y a quelques semaines. J’utiliser mon PC sur secteur.

[quote=“cedric058”]=> Solution: Désactiver les gifs animés dans Iceweasel. (Pour Chromium c’est à voir)
about:config
Changer la valeur de la ligne “image.animation_mode” de “normal” à “none”.

J’ai fait le test => plus de ventilateur, CPU à 4% en éditant ce message au lieu des 60% habituel.[/quote]
Je viens d’appliquer cette option sur mon vieux X60 (équipé d’un CPU monocore cadencé à 1,67 GHz), et j’ai pu observer un gain similaire : de ~60 % de charge CPU à moins de 5 % sur la même page de rédaction de message du forum.

Maintenant je me demande si je ne vais appliquer cette même option sur ma bête de course… Le gain de disponibilité du CPU sera négligeable sur celle-ci (un quad-core cadencé à 3,40 GHz), mais je n’ai jamais été un grand fan d’avoir des images animées en train de me distraire quand je lis/écris.

#16

Je confirme, la différence est flagrante. Cette manip’ a résolu le problème de surchauffe sur mon portable, lorsqu’on rédige un message sur un forum.

En revanche je n’ai toujours pas compris pourquoi Agentsteel me parlait de laptop-mode-tools. J’avais regardé la doc, ce qui m’avait laissée perplexe.

En tout cas, j’ai l’impression qu’il n’y a pas de solution miracle, juste des “petits trucs” qui améliorent les choses!

#17

l’intérêt de laptop-mode-tools c’est qu’il applique automatiquement (et dynamiquement) des optimisations pour la gestion de l’énergie, selon que l’on est sur batterie ou sur secteur.

Mais effectivement en l’absence de batterie on ne verra pas de grande différence :stuck_out_tongue:

#18

Cette discussion est en train de virer à la mine d’or pour mon vieux PC portable !

Sans compter que je me sens moins seul à faire tourner mon X60 avec un BIOS alternatif (libreboot dans mon cas).

#19

[quote=“agentsteel”][quote=“minerve”]Bonjour à tous, j’ai un problème sur mon Thinkpad X60 qui tourne sous Crunchbang Wheezy. Ce Thinkpad a un BIOS Coreboot, et, bizarrement, lorsque je veux rédiger un message pour un forum de discussion comme celui-ci, le ventilateur se met à tourner à la vitesse maximum, la température du CPU augmente à toute vitesse, et la machine finit par s’éteindre.
Le phénomène est moins apparent lorsque je veux regarder une vidéo sur Youtube.
Bien sûr, j’ai pris les mesures habituelles: démontage de la machine, dépoussiérage soigneux, et changement de pâte thermique, avec un résultat mitigé.
J’ai remis à jour le BIOS, ce qui a eu des effets assez spectaculaires car la température a chuté de 25° au moins. Mais malheureusement le phénomène est revenu au bout de quelques mois.
Est-il possible qu’il s’agisse d’un problème logiciel? La commande Top me montre que ce qui prend le plus de ressources, c’est Xorg, et Chromium lorsqu’il tourne.
Merci d’avance pour vos idées!

[edit] je donne le noyau: Linux debian 3.2.0-4-686-pae #1 SMP Debian 3.2.65-1+deb7u1 i686 GNU/Linux[/quote]

Je commencerais par installer un noyau plus récent (depuis les backports) pour voir si cela améliore la gestion de l’énergie, ainsi qu’un outil de diagnostic comme powertop.[/quote]

J’avais essayé, ça chauffait encore plus (et difficile de revenir en arrière :confused: ).
