Computer or Laptop running 24/7?

Do you leave your Computer or Laptop running 24/7?

Some experts say that it is better to leave your Computer or Laptop running around the clock than to shut it down at nighttime and boot it up in the morning when you wake up. One of the reasons behind is if you never shut your Computer down, you will save any damages and extend the life of you computer?

Electricity is really expensive and if you don’t care on paying your monthly bills or consuming a lot of energy you have the option to leave your computer the whole night. It takes lesser energy to boot your computer in the morning rather than to leave it running overnight. Computers need also to do some maintenance during starting up and shutting down. Operating systems need to get the necessary updates as well.
In my own case, I make it to the point to shut it down my computer or even my laptops at night before I go to sleep. I don’t want that all of my hardwork and the sweat of my brow will just go playing my electrical bills.

"You shouldn't waste energy to extend the life of a computer by even a very small amount" and discounts the notion that "shutting down and starting up a computer puts undue stress on the components, noting that most systems are retired because of obsolescence, not because of hardware failure."
