kernel32.dll and GetSystemPowerStatus

[Grovkillen]

Code: Select all

LibFunc>kernel32,GetSystemPowerStatus,Test,powerStatus

Gives a weird string in return. Could someone guide me to how to interpret it?

BTW, this only return the array "TEST_1=powerStatus":

Code: Select all

LibFuncW>kernel32,GetSystemPowerStatus,Test,powerStatus

I found the syntax here: https://docs.microsoft.com/sv-se/window ... owerstatus

Code: Select all

LibFunc>kernel32,GetSystemPowerStatus,DecimalOfBinary,REF:0

This gives me the byte wise data as a decimal, unassigned meaning I need to first convert it into ones and zeros and then pad it with leading zeroes accordingly.

I found out that this is possible with a bit of head banging... not completely accurate with the bit wise lookup but I post this as a work in progress to document my progress and perhaps someone else will pitch in.

Code: Select all

LibFunc>kernel32,GetSystemPowerStatus,DECIMAL_VALUE,REF:0

FYI:
I want to know the computer's battery status in order to act on it. So current percentage (which I seem to get with my script so far) plus if it's charging or not is what I'm looking for.

Ok, VBScript did the trick:

Code: Select all

VBSTART
Function BatteryInfo()
On Error Resume Next
strComputer = "."
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set colItems = objWMIService.ExecQuery("Select * from CIM_Battery")
For Each objItem in colItems
    BatteryInfo = BatteryInfo & _
                  "BatteryStatus=" & objItem.BatteryStatus & "|"  & _
                  "Description=" & objItem.Description & "|"  & _
                  "Voltage=" & objItem.DesignVoltage & "|"  & _
                  "DeviceID=" & objItem.DeviceID & "|"  & _
                  "Percentage=" & objItem.EstimatedChargeRemaining & "|"  & _
                  "MinutesLeft=" & objItem.EstimatedRunTime & "|"  & _
                  "Status=" & objItem.Status & "||"
Next

End Function

VBEND

Separate>TEMP,||,TEMP_BATTERY

Let>b=1
Repeat>b
  Let>TEMP_BAT=TEMP_BATTERY_%b%
  Separate>TEMP_BAT,|,TEMP_INFO
  Let>i=0
  Repeat>i
    Let>i=i+1
    Let>TEMP_VAR=TEMP_INFO_%i%
    Separate>TEMP_VAR,=,TEMP_VALUE
    UpperCase>TEMP_VALUE_1,TEMP_VALUE_1
