Electricity cost for laptop?

[nissangtr786]

Does anyone know if lets say I used my laptop for 2 hours a day for gaming at 70w power consumtpion and 4 hours at an average of 50w lets say browsing the web, using office and watching iplayer hd I checked iplayer hd takes 50w and I believe my laptop idles at 30w with full screen brightness.

So with that use how much killawatt would I use in a day and 7 day and 4 weeks and 1 year.

Unfortunately the silvercrest power consumption reader broke after only a week so I can't test anymore unless I get another battery lol and I know its cheap unless its the fuse or something if it has a fuse lol.

Also anyone else seen there power consumption readings and I know notebookcheck is a good site but does anyone have pentium 4 laptops and pentium m centrino cpu's to see the difference.

Also I reckon the most power hungry laptop components are i7 940xm and gtx 580m/675m single gpu wise so if anyone has anything like this it would be interesting to see if it takes 240w stress test.

Gaming: 70W x 2hours = 140Wh
Office work: 50W x 4hours = 200Wh
Idle with screen on: 30W x 10hours = 300Wh
8 hours sleep/computer turned off
Total: 640Wh per day

640W x 31 days = 19840Wh per month = 19.840 kWh
Cost per month: 19.840kWh x price per kWh (lets say $0.15)
Cost per month: 19.840kWh x $0.15 = $3

x12 = price per year for the use of your notebook = $36

So around £23.35 lol.

lol you beat me cloudfire...he is spot on depending on your location and prices for electricity. laptop gaming is by far the most economical. i wouldn't even think twice about leaving it on 24/7. ifyou can't afford that then you dont need a laptop lol

Sorry
Yeah I think anyone can afford 3 bucks a month lol. I do wonder about the desktop SLI guys with 24inch screens and everything though. Too lazy to look it up

We just did that calculation here about a month or so ago, question seems to come up frequently. If you just think about it, most laptops come with 65W/90W/120W PSU's even gaming notebooks come with 180W PSU's although are only draining probably less than 20W most of the time which is very minor power consumption. Pretty amazing if you think about it. Very little cost to run these machines.

hehe. mostly idle on my desktop at the moment, drawing 170 watts with one monitor on. gaming with single monitor...hrm...spiked up to 420 watts during a Dawn of War 2 benchmark (WoW doesnt stress my gpu's enough)

on average, i'm on WoW ~6 hours a day, rarely ever see my kill-a-watt monitor above 300 watts while playing that.

I read on some xps 9100 dell forum I believe that they used to take 105w and some seller on ebay sold them 2-3 years ago going by d......90 (leave ..... just in case you are not allowed to name) sold them for $1000 trying to make them look like supercomputers and then got and xps m1730 and sold them for double how much they usually go for. Imagine how many pentium 4 pc's are out there when an atom or basic c50 cpu will do the job on full load taking 80w less on full load then a p4 3ghz system on idle.
