Bonjour,
J'ai depuis plusieurs semaines un Asus BX425EA avec Ubuntu 20.04 LTS et Windows 10 en dual boot. J'ai récemment remarqué que la batterie se décharge vite lorsque l'ordinateur est en veille : elle perd environ
12% en 10h de veille. Ça me semble beaucoup ! (À titre de comparaison, avec mon ancien Macbook pro, après 7 ans d'utilisation de la batterie, elle perdait moins de 10% en 20h de veille).
Je suis donc allé voir le type de veille effectuée :
cat /sys/power/mem_sleep
Et je vois que c'est s2idle :
[s2idle] deep
Je me dis que la décharge rapide de la batterie peut venir de là, donc j'ai voulu essayé le mode veille profonde :
echo deep > /sys/power/mem_sleep
s2idle [deep]
Puis, je met s l'ordinateur en veille, mais quand je le réveille, tout ne se passe pas bien : le son ne fonctionne plus, les touches F1-F12 sont bloquées comme si la touche FN était toujours active sans que j'ai la possibilité de changer...
Pour essayer de voir ce qu'il se passait, j'ai fait après le réveil :
dmesg | tail -50
Et voilà ce qu'il me renvoie, à partir de la mise en veille profonde :

À ce stade, ça dépasse ma compréhension des choses, quelqu'un saurait-il m'aider ?
Merci de votre aide
