The actual device has passed both pcba test and final device test.Root cause analysis done in trended case states- by visual inspection it is observed that the surroundings of the usb interface has been deformed by heating.The usb connector in the device, as well as the connector on the cable are further investigated with a microscope.Functional testing reveals that the charger works fine, when running on the internal battery.That means that the malfunction in the device is purly a breakdown of the micro usb connector.The connector is broken, probably because the user has (not intentionally) misused it, while inserting the cable.If the cable has been slightly out of specification that could have had a negative effect on this.This has caused a low ohmic connection in the cable connector - almost a short circuit - that will emit heat when the cable is inserted into the wall charger, causing up to the rated 5 w of the wall charger to be dissipated inside the connector.Micro usb is a very well known and used standard but can mechanically break down.Further information will be submitted as we get more follow up.

Sf (b)(4).Re charger- hot and melted.It was reported- hcp called tech support and reported that pt's charger got hot and melted at the junction of the charging cord and charger.Issue occurred on june 6th.Reportedly a new charger has already been sent to pt, but hcp was advised to call to report the issue.He said the charger with the issue has not been received yet, but he will send it to us.Hcp declined harm to pt.He read the notes from another provider that indicated the charger is still functioning, but damaged and occurred 1 time.Pt thinks a possible power surge.I advised to stop using the damaged charger.Hcp is unsure if has were in charger when the issue occurred.If has were in charger when the issue occurred, i advised to send the has in for evaluation as well.Qe form emailed to hcp.Flagged in navision.Complaint created.No harm was made to the user.This is a late case.This is an initial report.Further information will be submitted as we get follow up.
