So I have this 2013 MacBook Pro running Yosemite. Sometimes it will randomly shut down when running on battery power. It shouldn't be a battery issue, because it can be drained fully over several hours without random shutdowns. Sometimes it just happens completely randomly. It shuts down more often when the computer goes to sleep and I attempt to wake it up again (eg closing and opening the lid).
Does anyone have any idea what might be causing this? Any kind of diagnostics I can do?
