How Long Does She Last?

We are using the standard benchmark settings from Bapco, along with a few other minor system tweaks. The screensaver was disabled and volume was set at approximately 20%.

MobileMark 2002 utilizes the following applications:

  • Microsoft Word 2002
  • Microsoft Excel 2002
  • Microsoft PowerPoint 2002
  • Microsoft Outlook 2002
  • Netscape Communicator6.0
  • McAfee VirusScan 5.13
  • Adobe Photoshop 6.0.1
  • Macromedia Flash 5
  • WinZip 8.0

The white papers for MobileMark are available on Bapco's website should you want to read up on how this benchmark works. In the graph above, higher scores equal better performance.

The R52 isn't necessarily meant for a lot of road time, but it can do the job, when it comes to battery life. The standard 6 cell battery racks up about 4 hours of use, while the 9 cell can keep you away for just under 6 hours.


The down side of choosing a 9 cell battery is that it is a heftier battery pack and sticks out the backside of the notebook. Our personal choice, and other alternative to the larger 9 cell, is to chose a modular battery back for the notebook's Ultrabay, but this will mean you can't access CDs/DVDs.

Charge time for the batteries from 0% to 100% is as follows (real world numbers, not estimates):

  • 6 cell primary - 3 hours and 6 minutes
  • 9 cell primary - 3 hours and 57 minutes
