Do I need to set my ACPI as S3 supported?

[Envying]

Mac OSx needs S3 or S1 for Wakeing up?

 

Could this be the reason why my computer won't wake up from sleep, with default setting to S1 not S3?

 

Found some stuff about it...

7. Description and modification of the different hibernate modes

When the computer goes into sleeping mode, its behavior depends on a power management

variable called hibernate mode. The hibernate mode can be set to different values:

• 0 : Default sleep behavior on most Apple computers. RAM is still powered on while sleeping.

Wake up is fast. Safe sleep is disabled.

• 1 : Hibernation behavior. System is totally shut down while sleeping. RAM contents are

dumped to disk. Wake up is slow.

• 3 : Default behavior on Powerbook HD and later computers. RAM is still powered on

while sleeping. Wake up is fast. Safe sleep is enabled, so RAM contents are also

dumped to disk before going to sleep.

• 5 : Same as mode 1 for systems with encrypted virtual memory.

• 7 : Same as mode 3 for systems with encrypted virtual memory.

Only a single mode can be activated at a time. In order to check what hibernate mode is

currently active, the following command can be used in the Terminal application:

pmset -g | grep hibernatemode

In addition, users with administrator privileges can choose the hibernate mode. In order to

do so, the following command can be used:

sudo pmset -a hibernatemode X

with X replaced by the value of the hibernate mode to set.
