Is there any benefit to shutting down the computer at the end of the day?I am talking about a PC laptop. Is there any difference between simply...

If you have a program running on the computer then
naturally it makes no sense in turning off the computer or even putting it in standby
mode. every computer is meant to run programs and you can do this when you turn off a
computer.

But when you are not using the computer in any
way, that is neither actively interacting with the computer, or running some background
program, you have the option of shutting it down or just putting it in standby
mode.

The disadvantage of shutting down is the additional
time and effort of switching it on. And the disadvantage of leaving it on are primarily
the power consumption and the additional wear and tear of the computer. All this boils
down to basically money, and to some extent the the ethical issue of not wasting energy.
In any case the decision is heavily influenced by individual preferences. I personally
do not find the the trouble of restarting the computer too much if I do not intend to
use it for even for a period for an hour or two. I certainly don't keep my computer on
overnight, even if I am not working on it.
