Por que meu laptop é retomado imediatamente após a suspensão? [fechadas]

Parece que estou tendo algum problema com o modo de suspensão. Toda vez que tento suspender meu laptop, ele bloqueia a tela. Ou talvez ele seja suspenso com sucesso apenas para retomar apenas um instante depois. O que poderia causar esse comportamento?

Estou executando o Ubuntu 12.04 de 32 bits com o kernel 3.2.0-25 em um laptop HP dv5-1178er Pavilion (Intel Core 2 Duo).

Fri Jun  1 10:42:22 MSK 2012: Finished.

No HP Envy dv6, o seguinte funciona na 13.10 (após a atualização do 13.04; 13.04 não apresentava problemas de suspensão) usando o acpitool (1).

1. use acpitool -wpara listar dispositivos com capacidade de ativação.

Nó Sysfs do status do estado S do dispositivo

  ---------------------------------------
  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

Os dispositivos USB são 4,5,6. Como eu sei? Comparei os valores do nó sysfs com a saída delspci|grep USB

1. Use acpitool -Wpara desativar os dispositivos USB:

acpitool -W 4; acpitool -W5; acpitool -W 6

O problema semelhante ao acordar imediatamente após a suspensão existe no ASUS Eeepc 1201n:

A solução postada lá sugere adicionar dois comandos ao /etc/rc.localarquivo:

A solução que encontrei é muito simples e eficaz. O único problema que faz com que o laptop seja ativado são dois componentes USB que precisam ser desativados. Para fazer isso, edite o arquivo /etc/rc.local:

sudo gedit /etc/rc.local

Deve ficar assim:

 #!/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

Tudo o que fiz foi adicionar esses dois comandos:

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

Esses pedidos são para componentes USB que não permitiram que o laptop permanecesse suspenso. Desativá-lo do arquivo local não afeta o sistema

Se você deseja ver todos os componentes USB ativados para ativar o laptop, este é o comando. Você notará que esses dois não estão mais ativados (é claro após a reinicialização):

cat /proc/acpi/wakeup

Esta solução muito boa e simples, encontrei este fórum e o adaptei ao meu eeepc. Eu acho que é para muitos laptops com esse problema. Você só precisa adaptar o truque a cada máquina testando quais dispositivos USB são o problema. Você pode testar executando o comando acima mencionado para cada dispositivo e testando a funcionalidade de suspensão. Encontrei-o neste fórum: http://ubuntuforums.org/showthread.php?t=1969615

No meu Asus 1201N, adicionando apenas

echo US15 | sudo tee /proc/acpi/wakeup

para /etc/rc.localcorrigir o problema com a suspensão.
