Recently, we heard from a BenchmarkXPRT Development Community member who was testing Chromebooks in their lab. On a few of the Chromebooks, they saw sporadic CrXPRT 2 battery life test failures where CrXPRT 2 would successfully complete a battery life test and produce a result for the initial run, but then fail at the end of later runs.
After a considerable amount of troubleshooting, they determined that the issue seemed to be related to the way some systems automatically shut down before the battery is completely exhausted, and the way some systems will automatically boot up once the tester plugs in the power adapter for charging. This member found that when they added a few system configuration steps before battery life tests and made slight changes to their post-test routine, the systems that had previously experienced consistent failures would successfully complete battery life tests and produce results.
The added steps are quick and straightforward, and we decided to add them to the Configuring the test device and Running the tests sections of the CrXPRT 2 user manual. We hope this updated guidance will help to prevent future frustration for CrXPRT 2 testers.
