I have mountain lion on MacBook pro mid 2012.
So if my battery dies, because I left noSleep on or just because of being sat untouched for a week off of 2%, when I turn my computer on, Instead of the picture of the screen last used with the loading bar under it, the apple logo with the loading bar. I let it sit for a while, and it stays at the last bar of the loading thing. I wait and wait and nothing. I have to reboot using the power button to get it to work. A message then appears that said "your computer shut down cuz of a problem" . I have always saved my work , but I am assuming it would all be deleted if I had an unsaved word doc on low battery.
What is going on?
Things I have tried: reset SMC Reinstall OS on network recovery
And eventually if I have to, I guesss I will have to factory reset it
