I am building an Excel alarm clock for a laptop. I am updating the display
with an OnTime event. One of the requirements is to autonomously detect if
the laptop switches from A/C power to its internal battery.

Has anyone come across an API that will return the power state? Say TRUE if
A/C, FALSE if battery?

Thanks for any leads.

Maybe...

Private Declare Function GetDevicePowerState Lib "kernel32.dll" _
(ByVal hDevice As Long, ByRef pfOn As Long) As Long
http://msdn2.microsoft.com/en-us/library/aa372690.aspx

Private Declare Function GetSystemPowerStatus Lib "kernel32.dll" _
(ByRef lpSystemPowerStatus As SYSTEM_POWER_STATUS) As Long
http://msdn2.microsoft.com/en-us/lib...93(VS.85).aspx

Actually this looks to be the link and it contains some more info, about 2/3
the way down.
