Are there any Magsafe alert apps?

[Yr Blues]

Sometimes when I'm in a public place like a coffee-shop, someone that plugs into the same outlet I'm on would accidentally bump my adapter slightly off so that it doesn't get any juice. But I won't notice until my battery finally runs out and dies.

Is there an alert app for this?

It just happened. I lost about 15 minutes of work, oh well. My battery was already low, so it died pretty quickly.

You could always turn on the setting that dims the screen when you switch from AC to battery power. It's in System Preferences-->Energy Saver-->Battery, something like "Dim screen when on this power source." That always clues me in if I knock the plug off somehow.

The computer should warn you ~15min before the battery dies that it's going to die as well.

Get Growl and use HardwareGrowler (included with Growl in the Extras folder)

If you don't want HardwareGrowler to show an icon in your dock, right click on HardwareGrowler.app, click Show Package Contents, and add this:

<key>NSUIElement</key>
<string>1</string>

to Contents/Info.plist using your favorite text editor.

UnPlugged is an application to notify when the power cord of the Mac is unplugged or plugged in. Notifications are done using Growl, or with a Alertwindow, when Growl is not installed.
This app is done with Cocoa and doesn't use as much RAM and CPU usage as the other tools available. It contains icons for PPC and for Intel-Macs.
