For people that use a laptop at home for personal use, do you shut it down after each use or let it go into sleep mode and leave it on all the time? I know some laptops get warm or hot after a long period of time, so is it best to shut them down daily? It's only used at home for various times. Some days it will be used for 10-15 minutes and other days it may be used for 1-2 hours.
