This article contains a debate on “Is it Ok to leave the computer on or turn it off?” Letting the users decide for him or herself.

All of us require to move away from our computers at some point. A lot of users think if it is ok to leave the computers on, or we should turn them off. Its answer depends on various factors ranging from electricity bills to many other.

Is it Ok to leave the computer on or turn it off?

Associated costs

The major contributing factors when deciding whether or not to turn off your machine is the price of leaving it on. A bill for electricity can be costly and a computer—like many household electronic devices—is a contributing factor. So, if you are thinking to save a few dollars a month, shut down the computer when you are not using it.

Time to resume

In my opinion, the time for your computer to resume working is a more significant factor in the cost of electricity. For example, if you open and close your laptop frequently, you don’t want to have to reboot it thoroughly each time. Knowing about the different power states of a computer should help you with your decision.


Opened applications and files are saved in Ram. The rest of the computer components are put into a lower power state. This is the excellent option when you are just going to be going away from a computer for a short time.


In this mode, all of the open files and applications are copied onto your computer’s boot drive. The rest of the computer is shut down essentially. This is a good option if you are going to get away from your computer for a normal period.

Shut down

When your computer is shut down, all files and applications are closed. Shutting down is the best option if you will be away from your computer for a long time like more than eight hours.

Leaving your computer on overnight

My opinion for users is to switch off your computer when you go to bed to save money on your electricity bill.

Will switching off a computer wear down moving parts (e.g., fans)?

No. The only moving parts that caused problem internally were within a component, not the computer itself. In older hard drives, the head would come into contact with the disk platter upon shutdown, which caused it to wear. However, any hard drive manufactured today doesn’t have this problem.

Does switching off a computer cause soldering cracks?

No. Solder is meant to withstand changes in temperature; switching a computer off will not harm it. For example, many individuals turn their TV on and off each day, sometimes several times. Much like a computer, components within the TV get hot and cool down, and these devices have no problems.

Computer power misconceptions

“As the computer boots, it takes more power.

This statement is not true at all.

“Turing off my computer causes power surges.”

This statement is also not true.

“Leaving a PC on can cause the computer to overheat.”

It can get overheated only if the fan in the computer stops working.

“A laptop is different as compare to  a desktop; it should be shut down when not in use.”

A laptop can remain on for as many hours as a desktop. The exception here is if you are running a laptop off of the battery. In this scenario, the laptop will not be able to run all day.
