MBP Battery Issues

[catgo]

Hello, im having a problem with the battery on my macbook pro. I bought my computer about 3 months ago a 2.2 SR 15'', I installed leopard about 1 month ago and everything was fine until yesterday. Suddenly my battery only lasts about 1.5 hours instead of the usual 4 hrs. This started happening all of a sudden, I notice my battery health goes from 100% to 90% in about 10 - 15 minutes which is really fast.

I was wondering if someone has had this problem and if there is a way to reset something b/c i've tried restarting the computer 3 times with no luck.

Any help/suggestions would be great.

Thanks

My MBP is about the same age. I started having the same problem up to couple days ago when the battery would no longer hold a charge. I couldn't even put it in sleep while off the charger.

Took my MBP in to the Apple store for a Genius appointment and they replaced the battery and all is good now.
