Well I haven't, but I Googled for "WMi power management", found this as the 3rd hit: http://www.vbsedit.com/scripts/desktop/info/scr_233.asp which led me to look at this page in MSDN: http://msdn.microsoft.com/en-us/library/windows/desktop/aa394102%28v=vs.85%29.aspx and the PowerState attribute: """ PowerState Data type: uint16 Access type: Read-only Current power state of a computer and its associated operating system. The power saving states have the following values: Value 4 (Unknown) indicates that the system is known to be in a power save mode, but its exact status in this mode is unknown; 2 (Low Power Mode) indicates that the system is in a power save state, but still functioning and may exhibit degraded performance; 3 (Standby) indicates that the system is not functioning, but could be brought to full power quickly; and 7 (Warning) indicates that the computer system is in a warning state and a power save mode. This property is inherited from CIM_UnitaryComputerSystem. Value Meaning 0 (0x0) Unknown 1 (0x1) Full Power 2 (0x2) Power Save - Low Power Mode 3 (0x3) Power Save - Standby 4 (0x4) Power Save - Unknown 5 (0x5) Power Cycle 6 (0x6) Power Off 7 (0x7) Power Save - Warning """ which looks to me very similar to the SYSTEM_POWER_STATE struct you referenced from MSDN. Can you say whether this is what you're looking for? <code> import wmi c = wmi.WMI() for sys in c.Win32_ComputerSystem(): print sys.PowerState </code> TJG _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
