MacBook heating up and folder with question mark flashing
Almost every time I leave my MacBook (early 2016) plugged in over night (I rarely do that) I find a flashing folder with a question mark on the screen and a overheated casing (not extremely hot, but uncofortably warm). The heat seems to be evenly distributed so it could be the battery heating up. The OS is from a clean install, initially, and I already tried an OS reinstall twice, but problem persists. A error report is generated my the OS each time. Any similar cases? Thoughts or solutions?
MacBook, macOS High Sierra (10.13.2), Early 2016, 1.2 GHz Intel Core m5
