The reported complaint of the autopulse platform (serial # (b)(4)) does not power on was confirmed during functional testing.The root cause of the power issue was due to loose connection between the power switch cable and processor board likely due to wear and tear.The autopulse platform is a reusable device and was manufactured in june 2015 and is 6 years old, past its expected service life of 5 years.Upon visual inspection, a cracked front enclosure was observed, unrelated to the reported complaint.This physical damage is likely attributed to user mishandling such as a drop.Archive data review showed no significant issues.Initial functional testing could not be performed due to platform not powering on, thus confirming the reported complaint.The connection between the power switch cable and processor board was loose.The power switch cable and processor board were replaced to remedy the reported problem.During further functional testing, it was noted that the encoder driveshaft could not rotate smoothly, exhibiting binding and resistance, unrelated to the reported complaint.The root cause was due to the sticky driveshaft clutch area, which is usually caused by sharp edges from all 12-hex edges of the armature plate, or due to burrs on the surface of the clutch rotor, likely attributed to wear and tear.The impact of the sticky clutch was not severe enough to make the platform non-functional.The clutch plate was deburred to remedy the problem.After service, the autopulse was subjected to the run-in test using the 95% patient large resuscitation test fixture (lrtf) with good known test batteries until discharged without any fault or error.The autopulse passed all other functional testing.Historical complaints were reviewed for service information related to the reported complaint and there was no previous history of complaint reported for autopulse with serial number (b)(4).
