This is a question to which there is no definitive answer -- You'll get a
somewhat different response from just about everyone you ask
IMO, there is very little reason for anyone to leave *any* computer powered
on 24/7/365, whether it be a laptop or desktop system. If it isn't going to
be used for several hours -- such as over night -- shut it down. At the
least, shut down/restart once or twice per week.
Modern operating systems do a certain amount of "housekeeping" during
startup/shutdown which doesn't happen during 'sleep'. Unless you take the
necessary steps to get that stuff done it can contribute to odd behaviors.
