My MacBook Pro 17" (the early 2008 model) started shutting down unexpectedly when there is a good amount of charge left in the battery (~ 30 - 40%). It started doing this a few days ago.

I read some of the posts here, and tried resetting SMC, but that didn't make a difference. I know about the battery calibration, but since it's shutting down without warning I don't think that's feasible at this point.

The only thing I would like to know is whether this is a natural decay of my battery so I need to go get a new one myself, or it's not usual so I need to have Apple look at it and replace it potentially (I'm under AppleCare). The notebook is about 1 1/2 years old. The following information is from the System Profiler reading:

Charge Information:
Full charge capacity (mAh): 3148
Health Information:
Cycle count: 571
Condition: Replace Soon
