Why is my computer shutting down for no reason?
My aluminum MacBook is about 2 years old now. I use it very often, so perhaps this is just normal? It turns off randomly, without warning, with more than enough battery power left. It's happened 4 times in the past month or so and I'm beginning to get worried! It just happened today, after I unplugged my adapter for about 15 minutes. I left the computer off for 4 hours. When I returned to it, I plugged in the adapter and turned on the computer...turns out there was still 55% of the battery left! I really hope someone can help me figure out what the problem is...
Here is what my System Profiler says about my Power:
