Once installed, here's how to create an alert to monitor your power connector:
- Launch Proxi and open an Editor window (if it is not already open).
- At the bottom of the Triggers column, click on the Gear menu » Insert Trigger, and select Battery Monitor. This will add a Battery Monitor line to the Triggers column; select it.
- In the Settings column, where it says Trigger If, select Power Source and Changes to Battery.
- In the Tasks column, click on the Gear at the bottom and select Play Sound. In the Settings column, select Submarine (or other sound of your choice).
[robg adds: A couple of other options for monitoring the power supply connection are Unplugged, and (my personal choice) Growl plus the HardwareGrowler, which can monitor a lot of other hardware-related changes as well. I'm sure there are more out there...]
