Does a computer use less electricity when on standby?

  • I am just curious. What about hibernation? I don't want to have to turn my computer all the way off, but I don't want to waste power either.
    windows desktop!


  • It uses the same amount of energy as apposed to when it is on.


  • It should, since the Computer is shut off, it does actually consume Less Energy, as opposed to being Turned ON.


  • it use equal electricity whether on standbye


  • Most of us in the IT field, used to do one thing before leaving for the day from office,

    Press Ctrl+Alt+ Del and leave to home happily. That means your PC is still on..

    One normal PC in the sleeping mode (Hibernation) will consume 35 watts/hr.
    Based on this we will do a small calculation.
    For one week 24 * 7 = 168 Hrs
    Of this if we consider that we are working for 68 hours, then
    the PC is in sleeping mode for 100 Hrs a week. For one month 4 * 100 = 400 Hrs
    In a normal IT office, if we assume approximately 250 PCs are there,
    250 * 400 = 1,00,000 Hrs (Sleeping Mode)
    So the power wasted in an office in a month is,
    100000 * 35 = 3500 KWH or units.
    If the charge per unit is Indian Rs. 6, then totally the wastage value is approximately 21000 Indian rupees.




    Here the sad thing is not the money loss to the company but the power loss to the country. (Hope no company is bothered about this procedure of keeping the system in sleeping mode)




    Apart from the loss to the country we need to think of the efforts people are putting for producing the power in the Mines, Thermal Stations, Hydro electric Stations, etc. If this is to continue, the cost of unit power will go up & at one stage we will not get power even if we are ready to pay any cost.

    So before leaving to home take some time to shut down the PC and do some favour to the country and the organisation.
    If you feel that this point is to be considered forward this to all your friends.





    It is not only for IT but also for all the sectors..... ...
