HP Spectre x360 - USB C power port "burning" smell & no longer working

[zippitydoo1]

About 6 months ago, I wrote on the HP community board to address an issue I was having with the USB-C charging port and the computer's motherboard. At that time, I recall attempting to charge my laptop via the USB-C charging port, only to see that the power indicator was not responding to the charge cable and that the laptop was not charging. This state persisted for ~15 minutes before the entire laptop died and was not responsive in anyway -- it would not turn on, nor would it take a charge (through either USB-C port). I reached out to HP, and through discussion, we discovered that the motherboard had short-circuited through the USB-C power port. I sent it in for repair, and all seemed to be fine and dandy after receiving the repaired laptop and a brand new HP charger cord & adapter from HP.

That brings us to today: I plugged in the new power adapter & cord to one of my USB-C power ports on my laptop this morning and heard a "pop" & slight sizzling sound before seeing the laptop turn completely off. The power indicator was again no longer responsive despite having the power cord & adapter plugged in. Fearing a similar situation as had happened to me 6 months ago, I removed the power cord and rebooted the device. Thankfully, it still turned on. However, the initial USB-C power port I used was no longer responsive to the power cord, and it no longer charges through that port, nor does it recognize other devices I plug into that USB-C port. Effectively, it seems as though that USB cord is dead and no longer functioning. 

Thankfully, it seems that the other USB-C port is still working (for the time being), and I can successfully charge and use other devices through it. However, I am massively disappointed that the other USB-C port "burned out" so soon after being repaired by HP and that there might be another underlying hardware issue that is causing the rapid failure of the power supply on my device. Can an HP representative please reach out to me to re-address this issue?

I have brought your issue to the attention of an appropriate team within HP. They will likely request information from you in order to look up your case details or product serial number. Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).
