    Now that electricity prices are rising yet again, we're looking at ways to cut our consumption without increasing hassle. During the working day, our computers are generally left on and then put into hibernation just before bed-time.

    Would we use significantly less power if the computers were switched off instead of put into hibernation?

    What power regulation regime would readers recommend?

    I've always turned mine off even for half an hour.

    I have a device from electricty company, when I switch my computer off it turns all of my devices off i.e. printers, scaner, monitor and my skype phone. I have the same device down stairs on my tv, dvd and freesat box. so far I have had no problems.

    I can't really speak for power usage. But maybe you should ask yourself why you are putting it into hibernation rather than shutting down. Hibernation is handy if you want to go back to your computer and have programs, etc all as they were before and a slightly swifter start-up than it would be from a full shut down. If these benefits aren't really a big deal to you, shut down the computer.

    I generally always shut down my computers as I am never in need those features. I'm either on the computer for a long period of time, or not for a long period of time. I think Hibernating is probably more useful for laptops.

    I tend to use computers on an intermittent basis throughout the day. I find it a real pain to wait for a start-up every time I want to do something, hence the hibernation.

    I suggest that you read the manual. The manufacturer will tell you what power is being used in hibernation/sleep mode. It shouldn't be significant.

    Tip, The wear and tear as well as the potential for data corruption is at its highest during " Shutdown & Cold Start-ups " , The more you do, The more likely you will encounter issues, Its a bit like Russian Roulette, The heaviest power draw takes place during Start Up, Once done the power draw stabilises and is based on system load.

    That said power consumption from a machine that is just idling, Is not a big deal in the great scheme of things.

    Take the big server systems from around the world, Powered up the day of install, Then running 24/7 365 ....Wink

    Hibernating computers draw practically no power, Even the fans stop running on some systems.

    RTFM was my first move but manuals aren't always as helpful as we hope!
