Do you have to turn off your computer?

It depends how long you are planning on leaving it for. If it is for overnight or longer then, yes, turn it off. If you are leaving it for less then an hour then you don't need to turn it off. If you need to leave it but are planning on going back on then there should be a hibernate or sleep option to use on your computer. Hope this helps!

If you are not planning to use the computer for a long period of time, Turn it of.

f it may be idle for an hour or less, use the hibernate setting,
