Hi: I do not know under which section this post goes but my question is that I have decided to put my both pcs (one with windows 7 ultimate 64 and the other with linux mint 13) to sleep instead of shutting it down at night and turning it on the next day. So my question is this. IS it ok to put pc in sleep mode? I mean in regard to over-heating and shortening its lifespan or any other issues? Thanks in advance for your answers.
