Why Should I turn my Computer Off?

Should you turn off your computers everyday?

Why turn your computer off after using it?

The Pro’s to switching your Computer off,

  • A reduced energy bill.
  • Whether you use an SSD (Electronic Drive) or HDD (Mechanical drive), turning your computer off will prevent the hours (wear and tear) from building up. SSD’s are rated for tens of thousands if not hundreds of thousands of hours, but it all counts right?
  • Most computers will respond well being shut down occasionally, it often fixes little bugs or software processes/resources that are not performing correctly.
  • Often, different programs/software updates will require a restart to install correctly.
  • Windows Updates will have a better chance of installing and being kept up to date. Even though Windows 10 has an “Active Hours” function which is designed to install and auto-restart your PC when you are not using it. We have found a lot of PC’s can go up to 6 to 10 months without installing any updates. This function does not always work as it should.
  • Although it falls under software, your Anti-Virus program will require restarts to install some of its new updates to keep you are your PC safe.

The Con’s to switching your PC off,

  • If you have an older computer or a worn hard drive, it will take longer to boot when you turn the computer on each time.
  • Some lesser developed parts will wear quicker when being turned on and off which is usually a result of the part’s temperature becoming cold, then hot, then cold etc.
  • Having to spend the time reopening programs and what you are working on.
  • Updates for Windows & Software can’t download when switched off, which means they will consume a portion of your internet bandwidth while your PC is turned on.
  • You can’t run disk defragmenter and any other tasks you require while you are asleep or away from your computer.

  • Turning my computer off will prevent power surges. This is untrue. Power surges from faulty appliances in your house or even a lightning strike only require your power cord to be plugged into the wall for your computer to be damaged. A lightning strike can travel through your Ethernet (internet) cable that is plugged into your modem/router. We have seen this firsthand. Quality surge protectors are recommended to prevent surges.
  • When I turn my computer on, it uses more power. This is untrue. A standard consumer computer does not use more energy when booting.

In Summary,

If you are only using your computer a few times a week, we recommend turning your PC off after each use.

If you are using your computer a few times a day or for lengthy periods each day, we recommend you turn it off once a day, or if you are exceptionally busy, at least 3 times in a 7-day week.

These suggestions are what we find to work best and be reasonable & practical for most users.
