O laptop liga novamente após a suspensão, mas somente quando conectado

Question

Estou executando o Ubuntu 16.04. Eu posso colocar meu laptop em suspensão por vários métodos ( pm-suspend , menu de energia canela, suspender botão de hardware).

Isso funciona como esperado quando o laptop está funcionando com bateria, mas quando eu o suspendo enquanto estou conectado à energia CA, ele volta a ligar-se alguns segundos depois. Quando inicializado no Windows, no entanto, a suspensão funciona normalmente na alimentação CA.

ATUALIZAÇÃO: /var/log/pm-suspend.log não mostra nada.

Veja o que eu vejo em /var/log/syslog : poder parece retomar imediatamente após suspender 3/4 núcleos de CPU.

/var/log contém todos os arquivos de log do sistema. É provável que o arquivo syslog seja o que você deseja verificar.
