O desktop Dell adormece em poucos minutos, ignora as configurações de energia / proteção de tela

Question

A torre Dell Inspiron dos meus pais entra em suspensão dentro de ~ 3 minutos de inatividade, apesar de todas as configurações de energia no Windows (protetor de tela, desligar a tela, entrar no modo de suspensão, desligar o disco rígido, etc.) ou desligado ou definido para 60 minutos.

Esta resposta afirma que a Dell é conhecida por empacotar seus computadores com software que pode substituir essas configurações, mas não fornece quaisquer detalhes (o problema para esse usuário era estar inconsciente das configurações avançadas; estou ciente disso). O único software da Dell que posso encontrar em execução no computador é o Dell Backup & Recuperação, o que certamente não parece ser um provável culpado.

Checando o Visualizador de Eventos para eventos de sono, eu acho que é apenas um evento do Kernel-Power dizendo "O sistema está entrando em suspensão. Motivo da Sono: Sistema ocioso".

Answer 1

O conteúdo da sua entrada no registro de eventos mostra:

Description:
The system is entering sleep.

Sleep Reason: System Idle

Isso parece indicar que você possui um plano de energia que diz ao sistema para dormir após um período de tempo ocioso. No seu caso, provavelmente cerca de 3 minutos ou 180 segundos.

Comece executando powercfg -q em um prompt de comando. O que você verá são todas as configurações do plano de energia ativo para o usuário conectado. A primeira linha da saída dirá qual plano é nomeado, seguido por todas as configurações individuais. Você provavelmente está interessado no valor Sleep After , listado em segundos hexadecimal - 3 minutos seria B4. Verifique duas outras entradas relacionadas a tempo para ver se algum outro pode corresponder ao ciclo de sono de aproximadamente 3 minutos que foi perdido .

Se não for encontrado acima, você pode usar powercfg -q para listar os planos de energia disponíveis no computador. Você pode copiar e colar cada GUID do esquema de energia no comando powercfg -q <guid> para ver as configurações de quaisquer outros esquemas de energia no sistema.

Aqui está um exemplo de consulta do esquema Power Saver :

C:\WINDOWS\system32>powercfg -l

...

É possível que você tenha perdido alguma coisa ou tenha cometido um erro com relação ao plano de energia ativo. Mas, a entrada do log de eventos é bastante clara que é um valor de tempo limite ocioso colocando o sistema em suspensão e não alguma outra parte do software ou driver, etc.

O Dell Power Manager e Dell Command | O Power Manager é instalado e usado apenas em laptops. Você indicou que tem um desktop, portanto, não há nenhum software de gerenciamento de energia incluído e é improvável que qualquer outro software de gerenciamento de energia esteja em um computador desktop.
