Analysis of the handheld was completed on 11/03/2015.During the analysis, it was identified that the handheld would not power on.The cause for the anomaly is associated with a swollen main battery.The swollen battery bent the battery cover causing the battery latch switch to register that the latch was unlocked, thus preventing the handheld from powering on (this condition can also cause the handheld to power off intermittently, but cannot cause the handheld to freeze while in use).No further anomalies were identified.Analysis of the software was completed on 11/03/2015.No anomalies associated with flashcard software were identified during the flashcard analysis.The flashcard and software performed according to functional specifications.
