Because I work on it in 3DS, Unreal and Photoshop so ill be working for hours and we found that it is cheaper to run my laptop because I can run these programs in the laptops eco mode. It was costing close to £1 (I think) an hour on the meter to run the PC.
Either way I havent used the machine because the past few times ive used the PC there's been a big chun taken out of the leccy meter and the laptop doesnt take much.
I know what you mean, my laptop, clocked down to 900Mhz in eco-mode, is more than fast enough to run everything I use it for (intensive user - core2duo) and only uses 27w in eco-mode and 36w it full throttle.
When you consider the average PC uses 100w+, it makes a massive difference, the bigger the screen, the bigger and brighter the CCFL, hence the more power used to operate.
Wow, didn`t know that I thought desktops used little power, SO does that mean (my last pc had a 600w power supply, normaly they are around 400w) it would have been using around £1:50 per hour?
Afaik, the average price per Kw is ~13p, so even pulling 1000w it would only be £3.12 per day.
But over a month thats when you start to realise how much you can save - people change eletric supplier to save £20 - £50 per year, you can easily save in excess of that by using devices correctly.
How do you work this out guys? there are two of us here so the laptop and the PC is on very regularly at the same time so would be interested to see how much this is costing me.
