Hello, everyone!

I have a MacBook Pro 17" 2010 - it has recently started shutting down randomly only when running on battery. Battery has 80% health.


In the console is says Previous Shutdown Cause: -128, but I can't find anywhere what that code means.


If anyone has any idea what this could be, I would be really grateful!

Thanks in advance!

MacBook Pro, OS X Mountain Lion (10.8.2)
