Energy: VS desktop computer laptop




by sangonesall6 » 08/09/09, 17:40

Good evening, I have two computers a laptop toshiba satellite m305-s4819 (we did not mark on the DC battery 10.8V = 3700mAh and on the input adapter: 100-240v output 19v). the desktop is an HP compaq dx2300 microtower with a hp L1908w display and an XPSoHo 650 inverter. I would like to know which 2 I should use the most to reduce my consumption. thank you in advance

Hello,
logically it should be the laptop that consumes the least! The best thing would be to take measurements ... especially since we have very little information on the computer. How much amps delivers power from the laptop?

on the laptop's power adapter we have marked: input: 1,3A and output: 3,95A
on the screen hp: 1,1A
on the inverter input: 3,9A output: 2,7A
I have nothing on the tour

: Arrow: Laptops are optimized to consume as little as possible, ON THEIR BATTERIES.
But the same is true of the performance of the power supply and charging cycles.
:?:

For the moment the central units have very disparate consumptions. A standard has just been created to put things in order ...

I have just discovered "all in one" type PCs and I think my next PC will be in this category.

I hope his consumption will be related to the concept. :?:

Hello

the higher the frequency of the processor, the more consumption and heat dissipation.

the ideal would be to have a CPU with a high frequency of operation and the sub-clocker (inverse of over-clocking) so that it dissipates less heat, may even be without fan on the radiator. as well as choosing an integrated video card (with dedicated memory, better performance) because the video card consumes a lot too. as well as allowing the hard disk to be put on standby: 5 to 10w all by itself, etc ...

every W saved is important. likewise, I now use the "hibernation" function. thus, I artificially put my computer into hibernation as soon as I have to be away from the screen, if only for 5 minutes. some central unit accepts a standby, where only the RAM remains supplied with low power: ideal standby because the restart of the PC is very fast, return to the workspace, for my computer, in less than 5 seconds after pressing the power button on the computer.

do not forget that a flat screen consumes almost as much as a CRT screen. also knowing that the small tubes for the backlight of the flat screen have a life time between 15 and 20 000 hours, between 2 and 3 years, lit 24 / 24. so think about putting the screen on standby as soon as you need it more.

..........

for a laptop, the standard power supplies are mainly 90 W of power, compare with PC power supplies happily delivering 150 to 500 W depending on the type of power supply and the need of the person in front of the computer: a " gamer "is the one who will make his machine consume the most. without forgetting the consumption of the screen that must be added !!!

otherwise, if the use of a hard drive is superfluous for you (no update of the system), a live CD is a good compromise, total insensitivity to the virus and other junk of the same ilk.

to achieve one to your measure, use PEBUILDER on http://www.nu2.nu/pebuilder/ , open access program and well documented (English only). the result of a disk create with this program depends on the version of Windows that you will use.

in this case, you can have your PC without a hard drive, but with a CD or DVD drive, just a USB key to save your data. and to shut down your machine, all you need to do is turn off the power to the computer, no need to use the Windows procedure to shut down.

Hibernation saves a memory image on the hard drive equivalent to your computer memory capacity, so the more RAM you have in the computer, the larger the file. prefer Windows XP to VISTA, which is much lighter as operation, especially more, that Windows 7 just released or will be released shortly.

the disadvantage of PC all in one is that they are often made with a motherboard with integrated processor, so office exclusively, any improvement being impossible, a single port for the RAM.

if your use is limited to office automation, choose a more classic configuration, with more RAM ports, 2 or 4 depending on the cards, by putting a slower processor, therefore less heating, and especially less expensive. you can thus build yourself a tower for a price practically equivalent to an "all in one" but with much better performances. keep the XP system, but by limiting the services installed: the less loaded in memory, the more the processor is free for your applications.

On average a laptop, charged battery, from taking to the user, consumes half the power of a desktop PC.

50 to 60W for the laptop
90 to 130W for the desktop PC

For 90% of uses (excluding games) a laptop is enough!

There must be a lot of comparisons on the net above.

Otherwise here is a calculator for estimating the consumption of your pc or laptop here

Otherwise notice to specialists: I will be interested to see a curve of evolution during the last years of (k?) Wh / Mflops ! In my opinion it has dropped!

In any case me since I bought my netbook, I do not start my desktop PC anymore.

To surf is enough.

Ben I envision an all in one for the following domestic applications:
- surf on the net
- spreadsheet
- word processor
- Streaming video and radio programs
- podcast
- management of personal finances
- archive management of image and sound files
- ...

For the software suite and the operating system, I boycot microsoft and use Linux and open office.
after 2 years of use of mandriva, I just spent very recently under ubuntu with great satisfaction even if I still have some details to settle ...

Good evening

all in one or classic desktop pc, that's the question!
if it's a question of aesthetics or place, it's sure that an all in one will be ideal, otherwise, this afternoon (9 / 9 / 2009), while surfing on cdiscount, I recover the data to make a complete assembly of a tower.
Here's what I found:
Gigabyte 73PVM-S2H 50 € 3ans
Intel Pentium Dual Core E5200 55 € 3ans
Kingston KVR667D2N5 / 1G x 2 30 € 10ans
Hitachi 500 Go 16 Mo 42 € 3ans
Samsung SH-S223E / BEWE 18 € 2ans
Mad-X Black Nightfever 29 € 1an
Speedlink Meteor Multimedia Keyboard Black 10 € 1an
Logitech RX250 Optical Mouse OEM 8 € 3ans
Asus 21.5 "VH222D 117 € 3 years

which gives in all, screen included 359 € as well as a guarantee of 3 years on the main parts, except the DVD player, the box, and the keyboard
