Determining Input Voltage

Post by IntensePC_User »

Hello,

I'm wondering if it is possible to determine whether the IPC is running from a power supply or battery.

For example, we run our IPC's with a 13.8VDC power supply that only switches over to a battery when AC power is lost. The battery voltage under load is around 12VDC, so there is certainly a measurable difference in input voltage under this condition.

Is it possible to detect when the system changes to the lower battery voltage? I'm running Windows 7 and would be perfectly happy to use WMIC or PowerShell if necessary.

Thanks.

The system doesn't incorporate such mechanism as designed to be always on wall power supply.
