Hi All,HPAA tool is developed by HP Diag team. It has been applied for all sustaining NB DT platforms to facilitate EOLA Functional testing for all ODMs. It’s quite similar with pre-test Diag test, but it works under customer image to instruct OP item by item. Test ( If I’m wrong, please correct me, Liz). So firstly factory need clarify issue could be replicated on those units which have never been run HPAA tool.
