I am curious to know which one my computers does and if doing either one of them hurts my SSD. Currently after so many minutes ( I have no idea how many, it just does it) the screen goes black and all I need to do is hit a key or a mouse button and it goes directly to the log in screen for my desktop since I have a password. Other times, like when I go to sleep it will show a blue screen, probably b/c the T.V. ins't turned off and I still just need to hit a key and it goes to the log in screen. Which mode is this? BTW...it's not a BSOD jsut fyi. Should I hibernate, sleep or turn it off every night?
