As soon as I unplug power, the computer dies. The system is also saying Replace Now. Here's a screencap from Coconut... If you can't see it, the capacity is shown as 1301% more than original. I don't think that's right. This all seemed to start after installing Lion about 6 weeks ago. I've tried resetting PMU and PRAM, conditioning, etc. Any additional thoughts before I trash the battery? This is a replacement for my original battery and isn't even a year old. Trouble is I can't find a receipt and to be honest, I don't even remember where I bought it. The computer works fine. No other issues. Upgraded HD, 2GB RAM and a new logic board about 2 years ago, following an incident with a friend's cat. Great machine. Lousy batteries.
