Last week I wrote about one of my pet peeves about Apple's new MagSafe power connector: the fact that it comes out too easily and if you don't notice it will cause untold hardship when you find your battery completely discharged the next day.

Chad Brantly's excellent ChargerChecker 0.2 is a new donationware application that has answered my prayers. It alerts you when your MacBook Pro's power supply is disconnected. ChargerChecker works in conjunction with Growl to give you an on-screen notification when your MacBook's charger is connected or disconnected. 

New in Version 0.2:
- Improved CPU load
- Audible and visual alerts
- Improved Installation Process

With the release of the MacBook Pro, Apple also introduced a brand new power adapter that uses the MagSafe connector.  While this innovative new feature can save your laptop from being jerked off the table by a careless passer-by, many people have complained that their power adapter becomes unplugged inadvertently without them ever knowing it.  This can be a huge problem when you pull your laptop out in the airport to put the finishing touches on your upcoming presentation only to find that it was mistakingly unplugged and the battery is completely dead.

Install Growl and ChargeChecker in System Prefs > Accounts > Login Items and you'll never worry about a discharged battery again.
