Pourquoi mon ordinateur portable reprend-il immédiatement après la suspension? [fermé]

Il me semble que j'ai un problème avec le mode suspension. Chaque fois que j'essaie de suspendre mon ordinateur portable, cela verrouille simplement l'écran. Ou peut-être qu'il réussit à se suspendre juste pour reprendre seulement un instant après. Qu'est-ce qui pourrait provoquer un tel comportement?

J'utilise Ubuntu 12.04 32 bits avec le noyau 3.2.0-25 sur un ordinateur portable HP dv5-1178er Pavilion (Intel Core 2 Duo).

Sur le HP Envy dv6, les travaux suivants sur 13.10 (après la mise à niveau à partir du 13.04; 13.04 n'ont eu aucun problème de suspension) en utilisant acpitool (1).

1. utiliser acpitool -wpour répertorier les appareils capables de se réveiller.

Nœud Sysfs d'état de l'état S du périphérique

  ---------------------------------------
  1. P0P1   S4    *disabled
  2. KBD0   S3    *enabled   pnp:00:07
  3. PS2M   S3    *disabled  pnp:00:08
  4. EHC1   S3    *enabled   pci:0000:00:1d.0
  5. EHC2   S3    *enabled   pci:0000:00:1a.0
  6. XHC    S3    *enabled   pci:0000:00:14.0

etc

Les périphériques USB sont 4,5,6. Comment puis-je savoir? J'ai comparé les valeurs du nœud sysfs à la sortie delspci|grep USB

1. Utilisez acpitool -Wpour désactiver les périphériques USB:

acpitool -W 4; acpitool -W 5; acpitool -W 6

Le problème similaire avec Awake immédiatement après la suspension existe sur ASUS Eeepc 1201n:

La solution publiée ici suggère d'ajouter deux commandes au /etc/rc.localfichier:

La solution que j'ai trouvée est très simple et efficace. Le seul problème qui fait que l'ordinateur portable se réveille est deux composants USB qui doivent être désactivés. Pour ce faire, modifiez le fichier /etc/rc.local:

sudo gedit /etc/rc.local

Ça devrait ressembler à ça:

 #!/bin/sh-e
 # Rc.local
 # This script is Executed at the End of Each multiuser runlevel.
 # Make sure the script That will "exit 0" on success or Any Other
 # Value on error.
 #
 # In order to enable or disable this script just change the execution
 # Bits.
 #
 # By default this script does nothing.

 # Added by Carlos TD

 echo US15 | sudo tee /proc/acpi/wakeup
 echo USB0 | sudo tee /proc/acpi/wakeup

 exit 0

Tout ce que j'ai fait, c'est d'ajouter ces deux commandes:

echo US15 | sudo tee /proc/acpi/wakeup
echo USB0 | sudo tee /proc/acpi/wakeup

Ces commandes concernent des composants USB qui n'ont pas permis à l'ordinateur portable de rester suspendu. Le désactiver à partir du fichier local n'affecte pas le système

Si vous souhaitez voir tous les composants USB activés pour réveiller l'ordinateur portable, voici la commande. Vous remarquerez que ces deux ne sont plus activés (bien sûr après le redémarrage):

cat /proc/acpi/wakeup

Cette solution très bonne et simple J'ai trouvé ce forum, puis je l'ai adapté à mon eeepc. Je pense que c'est pour de nombreux ordinateurs portables avec ce problème. Il vous suffit d'adapter l'astuce à chaque machine en testant les périphériques USB qui posent problème. Vous pouvez tester en exécutant la commande mentionnée ci-dessus pour chaque appareil et en testant la fonctionnalité de veille. Je l'ai trouvé sur ce forum: http://ubuntuforums.org/showthread.php?t=1969615

Sur mon Asus 1201N, en ajoutant seulement

echo US15 | sudo tee /proc/acpi/wakeup

pour /etc/rc.localrésoudre le problème de suspension.
