A common question I often get asked is should I leave on my computer, or turn it off at night? It seems like the I.T. industry is very conflicted on this topic, but today I am giving my two cents on how I feel about leaving your computer on versus turning it off. The answer may surprise you!
My answer is...You should leave your computer on. Now I bet you're wondering why, and I'll get to that in a moment. I have very sound reasoning, logic, and almost a decade of experience in this business to support my answer.
Computers that are left on 24/7 are less likely to experience problems than computers that are powered on and off, the exception to the rule being portable computers (example: laptops.) The airflow portable computers have is not ideal to be left on 24/7, but desktop computers should be. Let me explain.
Before I go any further, I want to make a disclaimer. Obviously there is no way to guarantee that you won't ever have any issues with your computer, and I am not saying that. But you can put the statistics in your favor and use them to your advantage to increase the life expectancy of your PC.
Don't put your computer to sleep, don't let it hibernate, you are effectively turning it off. It's OK to turn off your monitor, but sleep and hibernation are intended for laptops and portable devices to extend the battery life of said device.
Electricity cost is very minimal. Desktop computers are sipping power from the wall. Computers today use very little power compared to computers of the past.
Turning on and off electronics will eat away at the battery life faster then just leaving them on.
There's a lightbulb that's more than 100 years old, that's been burning every single day. They have never turned the lightbulb off. That should showcase that electronics will last longer if you leave them on versus powering them on and off every day.
They actually have a livestream set up where you can watch the lightbulb live.
Here is a link to the Wikipedia article on the lightbulb as well.
