Como verificar no sistema Windows se ele suporta o estado desligado suave do S5 e ativa os alarmes?

Question

Eu pesquisei no MSDN e encontrei estado S5 . Mas eu não encontrei nenhuma linha de comando através da qual eu ainda poderia encontrar se o sistema que estou tendo que suporta o estado S5 ou não?

C:\WINDOWS\system32>powercfg /L

Existing Power Schemes (* Active)
-----------------------------------
Power Scheme GUID: 381b4222-f694-41f0-9685-ff5bb260df2e  (Balanced)
Power Scheme GUID: 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c  (High performance) *
Power Scheme GUID: a1841308-3541-4fab-bc81-f71556f20b4a  (Power saver)

C:\WINDOWS\system32>powercfg /waketimers
There are no active wake timers in the system.

Como posso saber se o meu sistema suporta estado S5 ou não?

Todos os sistemas suportam S5, pois S5 é definido como Full Shutdown .

Estado de desligamento do sistema S5

In the S5, or shutdown, state, the machine has no memory state and is not performing any computational tasks.

The only difference between states S4 and S5 is that the computer can restart from the hibernate file in state S4, while restarting from state S5 requires rebooting the system.

State S5 has the following characteristics:

Power consumption

• Off, except for trickle current to devices such as the power button.

Software resumption

• Boot is required upon awakening.

Hardware latency

• Long and undefined. Only physical interaction, such as the user pressing the ON switch, returns the system to the working state. The BIOS can also awaken from a resume timer if the system is so configured.

System hardware context

• None retained.

Estado Desligado (S5)

The soft off state is when the system fully shuts down without a hibernation file. Soft off is also known as a "full shutdown." During a full shutdown and boot, the entire user session is torn down and restarted on the next boot. Consequently, a boot/startup from this state takes significantly longer than S1-S4. A full shutdown (S5) occurs when a system restart is requested (or an application calls a shutdown API).
