Windows 7: StandBy / Hibernation off - Computer still powers off.

StandBy / Hibernation off - Computer still powers off.

Hi all,

I am using Win7.
I occasionally use
powercfg -h off
to disable Standby / Hibernation. Most often if I am running some long-time activities in the background where I am away from the screen.
I noticed, that the computer still powers down (not shutdown). This is confirmed with Event 42, Category 64, Keyword 4 (Information)

If I do
powercfg -a
I get (roughly translated)

Mode S1 not available
Mode S2 not available
Standby has not been activated
Hybrid Standby-mode.

Tha last line of this output catches my eye and I do suppose that instead of doing a normal StandBy, the system goes into hybrid standby.
This, however, is astonishing, since it is stated that
powercfg -h off
disables normal standby just as well as it does disable hybrid standby.

Does anyone have a clue as to why my system still powers down?

Thanks in advance!
Regards,
P.

w7 Has hibernation, sleep or a combo, hybrid sleep. powercfg -h off disables hibernation and therefore hybrid sleep, but not sleep.
Go to Control Panel\All Control Panel Items\Power Options\Edit Plan Settings and set put computer to sleep to never.

I think anything can be done by cmd line, but I'm not versed in the commands.

I think if you set minutes to 0 (zero) this'll do it for you:

powercfg -change -standby-timeout-ac minutes

Use dc in place of the ac as appropriate.
