TEST RESULTS

During testing the screen was adjusted to 4/8, more or less equivalent to 4/10 on our reference laptop, the Gateway EC1803h.

Running on AC power, the N220 used slightly more power than the 1005HA when idle, but slightly less on load. This is a bit disappointing as Intel's dual core Pine Trail D510M0 motherboard delivered some considerable power savings compared to its predecessor, the D945GCLF2 which was based on the first generation Atom platform.

The N220's power consumption was much impressive during video playback, in some cases using up to 3W less than the 1005HA. Unfortunately, Pine Trail didn't give the N220 the ability to play any of the high definition videos in our test suite that the 1005HA couldn't. If anything, playback was slightly worse as most of the clips were very choppy and the audio frequently went out of sync. The 1080p H.264 clip suffered from the occasional frame rate slowdown on the 1005HA but was watchable; on the N220, it was much worse, with the same problem afflicting 20~25% of the clip. The only video that would play smoothly throughout was the 720p x264 clip, but like the 1005HA, the software decoder CoreAVC was required.

Given that much of the hardware is basically the same, we would guess that operating system, Windows 7 Starter edition is in some way to blame.

Battery Life

To test battery life, we ran a series of tests to simulate real life web surfing and movie watching. The critical and low battery actions were disabled, so the system would simply shut down once the battery was exhausted as far as Windows would allow. WiFi was enabled obviously for the web browsing test.

For the web browsing test we loaded three websites into Firefox on separate tabs: Google News, Yahoo News, and CNN International. Using the ReloadEvery add-on, we set each tab to do a staggered reload every minute. This is essentially one page reload every 20 seconds.

For video playback we used an XVID encoded AVI (1324kbps video, 448kbps AC3 audio) played with VLC Player in a loop.

The N220 ran for 8:31 during our web browsing test and a tremendous 8 hours flat playing Xvid video, beating the 1005HA by 0:13 and 1:26 respectively. Our AC power tests showed that the N220 uses less power when playing video and on load, so if any kind of stress is involved, the N220 will probably outlast older netbooks and CULV laptops alike.
