My 3rd Gen (late 2013) MBP randomly suspends.
I will be in the middle of working on my MBP and it will randomly suspend so I have to hit the power button to wake. Pressing the power button resumes from suspend but then it will do it again within a few seconds of use unless I plug it in. Does not seem to necessarily be tied to the remaining battery life (happens more often < 40% but it's happened at 68% and I've gotten down to 5% as recently as this week without seeing the problem).
This is a core i7 machine with 16 GB RAM and a 500 GB SSD. Coconut battery reports that I still have 75%+ of the original battery capacity left. This is a machine that otherwise has plenty of life left in it if I can get this resolved.
Any ideas what could be wrong?
