RAM4:
This laptop has a DDR2 800MHz of 2GB.
Considering that the CPU of this laptop is just

The power duration for this Dell Inspiron

after Ididasmall survey formy friends, allof

How We Test and Data1. GraphicsCard
Forthegraphicscard,wedidatestfor
it to get the result. The test was done by
PerformanceTest7.0,whichisanobjectively
benchmark test software. We did theAdvanced 3D Graphics Test to benchmark
howwell the graphicscard performswhen
usingthemostcommonfeaturesofDirextX.

2. AudioCard

AudioAnalyzer,itsoneofthebestaudiocard
test software, RMAA uses audio card to testsample signals and then analyze the output
signalstogetaccuratelyperformancedata.
We did and cared more about the Total
harmonic detection and intermodulation
detection + noise, which should be low if the
audiocardisgoodenough.
Above is a screen shot of the RightMark
AudioAnalyzer test results (we did test again,

the test result of the four laptops, and lower
percentage better audio card performance.
There may have some error, since we cannot
make sure that all of the laptop in the same
testing situation, but we tried to insure that
theyareinthesimilarsituation.
Obviously, the old Gateway earned the
highest score of both criteria, and it was true
thatwhenusingthelaptopwecouldeasilyfind

and Toshiba, thesetwo laptops get the similar

5. HeatThe heat is hard to measure accurately
without thermometer, but some benchmark
software allow us see the temperature of the
CPU, thus, if we located the CPUs position of
the laptop and we could get the higher
temperature. We did the temperature test
