[python-win32] Standby/Hibernate

[Rickey, Kyle W]

Thanks Tim. That did the trick. I need to do more digging on MSDN. Most
of the google results I hit were people trying to prevent
standby/hibernate. Thanks again.

You need the SetSystemPowerState [1] function from kernel32. 
(And your process will need to enable SeShutdown as well).

<code>
import ctypes
import win32api
import win32security

#
# Enable the SeShutdown privilege (which must be present in your
# token in the first place)
#
priv_flags = win32security.TOKEN_ADJUST_PRIVILEGES |
win32security.TOKEN_QUERY
hToken = win32security.OpenProcessToken (
 win32api.GetCurrentProcess (),
 priv_flags
)
priv_id = win32security.LookupPrivilegeValue (
   None, 
   win32security.SE_SHUTDOWN_NAME
)
old_privs = win32security.AdjustTokenPrivileges (
 hToken,
 0,
 [(privilege_id, win32security.SE_PRIVILEGE_ENABLED)]
)

#
# Params:
# True=> Standby; False=> Hibernate
# True=> Force closedown; False=> Don't force
#
ctypes.windll.kernel32.SetSystemPowerState (True, True)

</code>
