system powers down due to low battery life. At the 7 percent battery life setting, MobileMark 2007 records a
timestamp once per minute. At the end of the benchmark, it compares the beginning timestamp to the final (last
recorded) timestamp. MobileMark 2007 derives its system battery life rating as the number of minutes between
the start and end timestamps.
We followed the run rules that MobileMark 2007 specifies here:

Test results

Figure 3 presents the MobileMark 2007 Productivity 2007 median battery life rating for the Acer Aspire Timeline
4810TZ notebook system. We conducted one conditioning run followed by three Official MobileMark 2007
Productivity 2007 runs. (Complete test results appear in Appendix B.)
Because screen brightness can affect the amount of energy a system consumes, we check the brightness of
every system we test and adjust it when necessary. We set the levels of brightness to match as closely as
possible and to meet MobileMark's required minimum brightness of 60 nits. We tested the system at 76 nits.

Workload
Our goal was to see how long the Acer
Aspire Timeline 4810TZ notebook battery
would last running BAPCo's MobileMark
2007 Productivity 2007 battery life
benchmark test. MobileMark 2007 is an
industry-standard benchmark BAPCo
created to measure system battery life and
performance.
MobileMark 2007 Productivity 2007 consists
of the following applications and
corresponding tasks: Microsoft Project 2003
(project management), Microsoft Excel 2003
(calculation sheets), Microsoft Outlook 2003
(emails, calendars, scheduler), Microsoft
PowerPoint 2003 (slide presentations),
Microsoft Word 2003 (formatted text
documents), WinZip Computing and WinZip
Pro 10.0 (compressed archives), Adobe
Photoshop CS2 (manipulated and
compressed images), Adobe Illustrator CS2
(manipulated images), and Adobe Flash 8
(vector graphics, animation).
MobileMark 2007 measures system battery
life in minutes. MobileMark 2007 records
system battery life at the start of the
Productivity 2007 benchmark, and repeats
the benchmark workload until the system
battery life is depleted, or until the notebook
Acer Aspire Timeline 4810TZ (76 nits)
