ChargerChecker is the best, most full-featured power state alert app available. It works in conjunction with Growl to give you on-screen notifications when your laptop's charger is connected or disconnected.
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.

Second that - this is not a truly "free" app and listing it as such is misleading. I think it's a nice little utility, but I'm amazed that the author thinks it's worth pestering users for money every single time you start your computer. Donationware is a great concept, but it doesn't lend itself to shareware-like harassment.
While the functionality is good (it's nice to have a visual warning when your PowerBook power supply is disconnected), this app is definitely NOT the one to use.
Problem: the application prevents the PowerBook from sleeping (Mac OS X 10.4.6 at least). I did extensive troubleshooting and finally attributed the problem to this app.
Second problem: ChargerChecker prevents the disk drive from spinning down. In addition to draining the battery more quickly (my life dropped 15-20 minutes when running this app), it made estimates of battery life unreliable.
Third problem: actually an issue rather than functional problem. This application phones home (Little Snitch revealed this).
I don't think your sleep issue is related to ChargerChecker. I use it on several laptops and have never had this problem.
The phone-home only happens once when you launch the app or when the daemon starts. This is checking what the current version is to give you update notifications. No personal information is sent.
Go to System Preferences > Energy Saver and change 'Other Options' Settings for: Battery to 'Reduce the brightness of the built-in display when using this power source'.
If the cord is unplugged the screen will dim noticeably. Of course it won't dim if originally at 1 bar, but if you're plugged into power why are you using the screen on minimum brightness?!
I use a similar piece of software to ChargerChecker. Yes, you could noticed a change in brightness, as you said, if the brightness on battery is high or both are low it wouldn't be noticable. I find though that even with differences in brightness I sometimes still don't realize the cord has been disconnected. Hence why the need for such an application.
Your method also doesn't take into account if the user has their display set to adjust to ambient light. Just because your screen dims doesn't necessarily mean that your power supply was disconnected.

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 ChargerChecker and never worry about a discharged battery again.

To the developer: I'd recommend using a disk image instead of a zip file to distribute the app.
Thanks for the review. The new version of ChargerChecker uses a disk image.
Unfortunately, useless.

Cheers.
