PC shutdown or stand-by?

PC shutdown or stand-by? – This question is relevant if you think about energy saving. Switch on and off frequently a PC may bring damages to the computer’s hard disk or the power supply.

The best for your computer is keeping it on while you think you may need it.

Reducing the on/off cycles is better for your computer health. However, keeping your PC fully on may be energy consuming.

If leaving a computer on all the time doesn’t sound well to you, think about an automatic way to bring it to one of the best states for energy saving: shutdown or stand-by.

Shutdown

Manually, you can do it by clicking your Windows start button and after, in the start menu, clicking the link with the same name: shutdown.

What happens then? Your computer will start shutting down every program you may have running and then switches off almost all its hardware.

This is the best state for energy saving. However, this is the most time consuming either for the shutting down phase and the resume one.

If this longer time for start/stop is not relevant for you, take shutdown as your solution.

Automatically, you may use your Windows scheduler application (Scheduled Tasks) and type into the run field a command like

according to instructions you may have a look at here.

This Windows application, Scheduled Tasks, give you many options including the precise hour you want to run a shutdown on your computer.

Like this, you can go to bed and Windows will take care of your energy cost reduction.

Stand-by

Manually, you can do it by clicking your Windows start button and after, in the start menu, clicking the link with the same name: stand-by.

What happens then? Your computer will not shut down any running program, it just keeps them in memory (RAM), but will switch off a major part of its hardware (hard disk and peripherals management).

Yes, in this case there is more electrical activity than the previous one but the difference in energy consumption it is not much relevant (in our opinion, of course).

Gains of this state? Much faster going off and going on, running programs before stand-by will resume smoothly.

Automatically, you may use your Windows scheduler application (Scheduled Tasks) and type into the run field a command like

according to instructions you may have a look at here.

This Windows application, Scheduled Tasks, give you many options including the precise hour you want to run a stand-by on your computer.

Like this, you can go to bed and Windows will take care of your energy cost reduction.

Automatic WakUp after StandBy

What about putting your PC everyday on a stand-by state by 9:30pm and start it up at 8:30am?

Yes, the idea here is to put your computer on an energy saving state all night long.

Here, we propose a small third-party application, very effective and freeware.

It comes with a good instructions pdf document and it works on Windows XP for sure.

We didn’t test it on Windows 7 but we guess it will work.

The freeware program we recommend is called WakeUpOnStandy and you may download it here. We wish you good savings, mainly if you have more than one computer at home.
