A getinge field service engineer (fse) was dispatched to evaluate the iabp unit and the fse could not duplicate the issue (it was plugged in and fully charged when he arrived) but the fse did find that the power log indicated power/charging was swapping between a/c power and battery power frequently while it indicated the source to be the bulk supply.The batteries were at 14% & 15% from 14:57 to 16:10 while the power source remained on bulk sr.The fse replaced the power management board and completed a full system test (pm protocol).All tests passed to factory specifications.The fse left the unit powered on (ac power) all weekend and there were no additional power activities, the batteries remained charged.Returned to the customer and released for clinical use.The following investigation was performed by technician of the maquet failure analysis and testing dept.(fat) wayne, nj.The failure analysis and testing dept.Received pcb, power management, rohs with a reported unit failure of the unit switching to battery power unexpectedly and ran the batteries down until it shut off.The failure analysis and testing dept.Performed a visual inspection of pcb, power management, rohs and observed white residue on component l10.Based on pas experience, this residue is consistent with saline.Capa 14-ca-0097 has been initiated to address this issue.Due to the saline spill on the board and the risk it poses, this part cannot be investigated any further by the fat.
