Se o cabo de rede estiver desconectado do computador ou o cabo de internet estiver desconectado do switch, a interrupção funcionará bem.
Existe uma porta encaminhada para essa máquina e aplicativo de torrent funcionando. Mas há problemas com a suspensão antes de entrar no perfil quando o torrent é iniciado.
Parece que algumas mensagens de broadcast estão interrompendo a suspensão via LAN.
Por favor, aponte alguns problemas para pesquisar. Obrigado.

Houve um problema no BIOS. Encontrado no site da Gigabyte (fabricante MB) correções para esse problema para revisões mais recentes do meu MB. A atualização do BIOS com o firmware mais recente da minha versão de revisão não tem efeito. Pediu fabricante para suporte.
O problema não está relacionado ao sistema operacional.
