Recently my macbook has suddenly been going to sleep out of the blue while I'm using it and Im not sure what could be causing it. Only two things that I'm thinking is either my harddrive is starting to go (which was replaced maybe two years ago?) or the logicboard is (which was also replaced two years ago, but it'll be three in march).

Also, no, I don't have any thing setup to send my macbook into sleep from doing any actions.
 
Bumping this back up as now my battery has suddenly dropped from 99% capacity to 83% and I just got this battery from apple back in february. I'm at 146 charge cycles and it was 100% capacity until I hit 140(yes I've been calibrating it). Any ideas on what's going on?

This doesn't strike me as abnormal. Resetting the SMC may bring your battery's health back up.
