[Economie batterie] Les meilleurs solutions pour PC portables (en cours)

Message par sullivan5959 »

Bonjour à tous,

Je n'ai pas particulièrement de problèmes mais je souhaiterai savoir quels sont les meilleurs moyens pour économiser et augmenter la durée de vie par différents outils.
J'utilise actuellement TLP qui fait du bon taf car il m'a fait gagné quelques minutes d'autonomie (une vingtaine) et mon pc portable ne chauffe quasiment plus sauf pour une utilisation plus gourmande. Cependant je voulais savoir si d'autres outils comme Powertop, Thermald, ou encore Laptop-Mode-Tools pouvait être plus efficace? Et est-il possible d'utiliser plusieurs outils en même temps? J'avais vu par exemple que Powertop pouvait poser problème avec TLP.

Avez-vous d'autres conseils pour encore économiser de l'énergie? Je vous demande vos conseils car avec Windows 10 installé en dual boot aune durée plus longue de quelques minutes (10 à 20min)

Je poste aussi le fichier de config de TLP voir si vous avez des changements à proposer:

Code : Tout sélectionner

# ------------------------------------------------------------------------------
# Set to 0 to disable, 1 to enable TLP.
TLP_ENABLE=1

# Operation mode when no power supply can be detected: AC, BAT
# Concerns some desktop and embedded hardware only.

# Hint: CPU parameters below are disabled by default, remove the leading #

Je ne connais pas Thermald, mais c'est Laptop-Mode-Tools qui je trouve est le plus complet par rapport à Powertop et TLP. Il est en effet conseillé de n'utiliser qu'un outil à la fois !
Pour Laptop-Mode-Tools, si tu as besoin d'un script supplémentaire tu peux lui en rajouter un facilement.
Attention à bien le configurer, il y a de très très nombreuses options, personnellement je n'ai rien en auto, j'ai passé en revu l'intégralité des options que j'ai modifié par rapport à mon besoin, je n'aime pas trop ce qui est fait par défaut surtout au niveau du disque.
Pour Powertop l'indication des valeurs optimals est étrange, si c'est différent de ce qu'il préconise, même s tu es plus agressif que ce qu'il propose, il te dira que ta config n'est pas OK. Donc il ne faut pas se fier au résumé. Et tout ce que fait Powertop est normalement géré par Laptop-Mode-Tools

D'accord, merci pour tes renseignements, j'essayerai Laptop-Mode-Tools prochainement.

Pour te renseigner Thermald est un outil qui empêche les CPU de surchauffer sans impacter les performances (je crois que cette outil vient d'Intel eux même).

Salut
Hier on a lancé chromium OS (linux 4.0.5) sur le notebook 17" Intel d'un pote, qui tient 2h sous Wiwi 8/10. On a bossé 2h+ dessus; il restait 45% de sa batterie =)
Le potentiel est là !
