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 T43 uses the same battery format as the R52 notebook, which is why they share the same batteries. In part because of the use of a discrete GPU, our T43 sample scored lower than the previously reviewed R52. Used as primarily a business/professional notebook, the T43 keeps pace with our expectations for battery life, ranking in at 3 hours and 39 minutes for a 6 cell battery. A 9 cell battery increases the time spent away from the wall jack up to 5 hours and 18 minutes.


As we noted before, 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 pack for the notebook's Ultrabay, but this will mean you can't access CDs/DVDs. The charge times were roughly the same, but each charge time varies a small time percentage due to the battery and timing margin of error.

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

  • 6 cell primary - 3 hours and 15 minutes
  • 9 cell primary - 3 hours and 53 minutes
