I've determined power usage on my desktop and on my server, but I hadn't gotten around to testing the power usage of my laptop. As battery life is always a concern with a laptop, I was particularly curious to see which parts of the laptop draw the most power. So I ran a few tests with my trusty kill-a-watt on my Dell Inspiron 300m. It's an ultaportable 2 pound laptop of late 2003 vintage with the following specs:
- Intel Pentium M 1.2GHz low voltage processor
- 640 megabytes of RAM
- 60 gigabyte hard drive
- 12.1' 1024x768 LCD screen
- Windows XP Pro
Let's start with some baselines:
Laptop off, battery charging | 63w |
Laptop off, battery disconnected | 1w |
Laptop off, sleeping | 1w |
Laptop on, idle at Windows desktop | 15w |

WhatsApp is free and offers simple, secure, reliable messaging and calling, available on phones all over the world. The newer Pentium Dual-Core processors give off considerably less heat (65 watt max) than the Pentium D (95 or 130 watt max). They also run at lower clock rates, only have up to 2 MB L2 cache memory while the Pentium D has up to 2x2 MB, and they lack Hyper-threading.
All subsequent tests were run with the laptop connected to AC power and the battery physically removed from the machine.

Watts Up For Laptop
Running 3dMark2001 produced a peak power usage of 29 watts. We can subtract the Prime95 number of 26 watts -- which is entirely CPU-only-- to estimate about three watts are used exclusively by the integrated Intel 'extreme'* video hardware.
Bear in mind the kill-a-watt is only accurate to plus or minus a watt. And these are all rough figures based on a sample size of one laptop. But I think the rules here can be generalized to most laptops.
Here's what I learned:
Watts Up For Laptop Touch Screen
- The CPU is, by far, the biggest consumer of power in a laptop. No surprise there. If you want to drain your battery lickety-split, run a bunch of apps that peg your CPU at 100 percent.
- Putting your hard drive to sleep isn't worth it. Ever. You save a whopping. single watt. Why bother?
- For maximum battery life, dim your screen. I was surprised that the screen alone accounted for 25% of the total power draw of my laptop at idle. You can moderate use of WiFi or your hard drive, but you can't exactly moderate the use of your screen. Plan accordingly.
Of course, your mileage may vary.
