Spectre not charging - USB-C ports not working

[TLent]

My HP Spectre x360 Model 14-ea0023dx suddenly stopped charging and stopped communicating with recognizing any devices (mouse, external monitor) connected to either USB-C port. I have powered down, rebooted, unplugged everything, and tried a different charger that I know works.

I am theoretically still well within warranty but can't figure out how to talk to anyone.

And I will run out of battery power soon of course!

Thanks for any ideas.

It took a winding road of HP chat and then a live tech who sent me to Best Buy Geek Squad without an appointment which apparently you do not do, who then told me that they would have to send it to HP for 2-5 weeks but suggested I call HP directly first to see if they could do faster.

Magic. The HP tech in India (midnight there) suggest we try "one last slim chance step" before sending it in, "in case it was a static charge problem". His steps:

Unplug everything.

Power down.

Hold the power button for at least 40 seconds

Release

Plug in the power adapter.

Voila the power light went on, and when I powered up the unit indicated it was charging and it recognized all other devices when I plugged them in to the USB-C

Problem solved!
