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.
