Quero alterar powercfg.cpl
"Opções de energia" diretamente pelo registro.
Especificamente, eu quero mudar isso:
Para essas configurações:
Estou usando um computador desktop em corrente alternada, portanto a economia de energia é desnecessária e prejudica o desempenho; Desativei a inicialização rápida no BIOS.
Eu abri esta chave de registro em regedit.exe
:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
E as únicas coisas que consigo ver dentro da chave são:
HiberFileSizePercent REG_DWORD 0
HibernateEnabled REG_DWORD 0
HibernateEnabledDefault REG_DWORD 1
Eu tentei usar powercfg.exe
e isso é o que eu tenho:
C:\Windows\system32>powercfg /l

Eu realmente não entendo nada disso...
Como posso usar um script para alterar automaticamente as opções de energia para as configurações postadas acima, pois não quero fazer isso manualmente?
As
powercfg
configurações não são muito difíceis de entender. Aqui estão minhas configurações de suspensão de exibição;As primeiras linhas contêm o identificador exclusivo da configuração.
Podemos definir os valores AC (ou DC) com o
/SETACVALUEINDEX
( ou/SETDCVALUEINDEX
)/l
no seu caso, as configurações ativas são as configurações de alto desempenho, que possuem um GUID de:8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c
7516b95f-f776-4464-8c53-06167f40cc99
3c0bc021-c8a8-4e07-a973-6b14cbcb2b7e
Este é o comando que você executaria para alterar as configurações de suspensão do monitor AC;
powercfg /SETACVALUEINDEX fb5220ff-7e1a-47aa-9a42-50ffbf45c673 7516b95f-f776-4464-8c53-06167f40cc99 3c0bc021-c8a8-4e07-a973-6b14cbcb2b7e 600
Isso está usando os GUIDs da minha máquina, definindo o tempo limite de suspensão para 10 minutos (600 segundos)
Você também pode usar os Aliases GUID conforme listado com o
/q
comando;SUB_VIDEO
é alias para7516b95f-f776-4464-8c53-06167f40cc99
VIDEOIDLE
é alias para3c0bc021-c8a8-4e07-a973-6b14cbcb2b7e
Presumo que esses nomes de alias sejam os mesmos em todas as máquinas. O esquema de energia não tem um alias. Então o comando seria;
powercfg /SETACVALUEINDEX fb5220ff-7e1a-47aa-9a42-50ffbf45c673 SUB_VIDEO VIDEOIDLE 600
Não importa, eu resolvi isso, novamente (mais ou menos).
Acabei de exportar a chave de registro inteira para um arquivo de registro chamado PowerCFG.reg localizado na área de trabalho usando
regedit.exe
.O arquivo é muito longo para ser postado aqui, e eu o converti para um arquivo ps1 que é ainda mais longo, eu os enviei para o Google Drive: PowerCFG.reg e PowerCFG_reg.ps1
O arquivo de registro possui 9.232 linhas e 645.546 caracteres, o arquivo de script possui 3.491 linhas e 855.339 caracteres. Acho que posso importar o arquivo de registro.
Entender os guids e hexes é muito difícil e vai custar muita energia, não é muito eficiente.
No entanto, como todas as configurações são armazenadas nesta chave de registro:
Simplesmente exportá-lo e importá-lo deve definir as configurações para o que eu quero que sejam, não preciso entender cada uma dessas chaves e valores, só preciso dizer ao computador para importar a chave.
Confirmei, basta clicar duas vezes ou
reg import
não importará corretamente as configurações, o acesso é negado;Então eu importei a chave por:
Com o privilégio TrustedInstaller, o comando foi concluído com êxito sem erros.
PS
Tentar executar o arquivo _reg.ps1 gerará muitos erros como este:
Os infratores são valores REG_BINARY.
