So I've got 2 UPSs connected to 3 PCs and with the USB connectors to 1 PC. The load is not even and they discharge at different rates. _WinAPI_GetSystemPowerStatus() gives me an average reading ( 1 UPS can be at 90% and the other at 10% ) but is lighter than WMI. WMI Win32_Battery gives me independent readings but is heavier to run. My question is: is there a DLL way ( as in the WinAPI call ) to get independent reading as WMI does ? ( This WMI code below is not needed to answer my question, but here it is anyway ) #include "Array.au3" Opt("MustDeclareVars",1) Opt("TrayIconDebug",1) Opt("TrayAutoPause",0) Global $_nice_COMerrorArray, $_nice_COMerrorObj _nice_COMerrorHandler(1) ; COM error handler.

Description = The availability and status of the device. For example, the Availability property indicates that the device is running and has full power (value=3), or is in a warning (4), test (5), degraded (10) or power save state (values 13-15 and 17). Regarding the power saving states, these are defined as follows: Value 13 ("Power Save - Unknown") indicates that the device is known to be in a power save mode, but its exact status in this mode is unknown; 14 ("Power Save - Low Power Mode") indicates that the device is in a power save state but still functioning, and may exhibit degraded performance; 15 ("Power Save - Standby") describes that the device is not functioning but could be brought to full power 'quickly'; and value 17 ("Power Save - Warning") indicates that the device is in a warning state, though also in a power save mode. 1.3.

CIMTYPE = boolean 26.2. Description = Boolean indicating that the Device can be power managed - ie, put into a power save state. This boolean does not indicate that power management features are currently enabled, or if enabled, what features are supported. Refer to the PowerManagementCapabilities array for this information. If this boolean is false, the integer value 1, for the string, "Not Supported", should be the only entry in the PowerManagementCapabilities array. 26.3. read = -1 27. SmartBatteryVersion 27.1. CIMTYPE = string 27.2. Description = The Smart Battery Data Specification version number supported by this battery. If the battery does not support this function, the value should be left blank. 27.3. MappingStrings = MIF.DMTF|Portable Battery|002.10 27.4. MaxLen = 64 27.5. read = -1 28. Status 28.1. CIMTYPE = string 28.2. Description = The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states. 28.3. MaxLen = 10 28.4. read = -1 28.5.

Units = minutes Win32_Battery Class Methods and Method Qualifiers ------------------------------------------------- 1. SetPowerState 1.1. Description = SetPowerState defines the desired power state for a logical device and when a device should be put into that state. The desired power state is specified by setting the PowerState parameter to one of the following integer values: 1="Full Power", 2="Power Save - Low Power Mode", 3="Power Save - Standby", 4="Power Save - Other", 5="Power Cycle" or 6="Power Off". The Time parameter (for all state changes, except 5, "Power Cycle") indicates when the power state should be set, either as a regular date-time value or as an interval value (where the interval begins when the method invocation is received). When the PowerState parameter is equal to 5, "Power Cycle", the Time parameter indicates when the device should power on again. Power off is immediate. SetPowerState should return 0 if successful, 1 if the specified PowerState and Time request is not supported, and some other value if any other error occurred. In a subclass, the set of possible return codes could be specified, using a ValueMap qualifier on the method. The strings to which the ValueMap contents are 'translated' may also be specified in the subclass as a Values array qualifier. 2. Reset 2.1. Description = Requests a reset of the logical device. The return value should be 0 if the request was successfully executed, 1 if the request is not supported and some other value if an error occurred. #comments-end
