MobileMark 2005 Battery Benchmarks Conclusions

The Fujitsu Lifebook P1510D's 28 Watt Hour standard battery kept the little laptop running for three hours and 10 minutes in the Research and Reading test, which is the least battery intensive test in the MobileMark 2005 battery benchmarking suite. Battery life dipped to three hours and four minutes for the Office Productivity test and only two hours and 35 minutes in the more hardware intensive wireless Web browsing test.

The P1510D performed decently in the Office Productivity test. It delivered a productivity score of 165 and an average response time of 1.47 seconds, which compares well with the scores of most of the other laptops in its class. Differences of even 10 points on the Office Productivity performance tests are minor.

With its high capacity 56 Watt Hour battery in place, the P1510D ran for six hours and 14 minutes in the Office Productivity test with a productivity score of 169 and average response time of 1.44 seconds. Based on the Office Productivity test, the high capacity battery should run the laptop in other situations at least twice as long as the standard battery. And here's the clincher: Even with its high capacity battery in place the P1510D still qualifies as an ultra lightweight laptop with a weight just a tad over 2.5 pounds. The high capacity battery does add ½" to the computer's depth.

The P1510D doesn't have a built-in DVD drive and Fujitsu included no dedicated external DVD drive. So the MobileMark 2005 DVD benchmark test was not run.
