Hello-

 

My 15" Macbook Pro (Late 2011) has started unexpectedly and randomly shutting down. I recently installed Mountain Lion and it started after that, and only seems to happen when running on battery power. I've tried an SMC reset multiple times and that doesn't seem to help. I'm running a 2.2 GHz Intel Core i7 with 8 GB of RAM, updated to 10.8.2.

 

Based on my battery report, I don't think that's the issue:

Anyone have any suggestions other than an SMC reset?
