Can't charge phone over USB-C?

[ntw3450]

So I tried plugging in my phone with a USB C to C cable (I have an S8), and when I do, the phone shows the charging animation over and over, indicating it's constantly getting connected and disconnected. It does not show up on my laptop either as a connected device.

The model of my laptop is HP Spectre x360 Convertible 15-df0xxx.

I've used a USB-C to USB-A adapter, and that allows the phone to charge. All the drivers are up to date.

In this case, follow this link and install the thunderbolt driver.

Let me know. 🙂

[ntw3450]

My Thunderbolt drivers have already been updated to that version.

Thanks for the response.

Try connecting the same adapter with a different port and see if it works. 

Keep me posted. 🙂

Neither USB-C ports will charge the phone. The USB-A port works fine for it.

Okay, so a quick update.

1) USB-C cable from laptop to phone: data works just fine, I can connect to and transfer files to the phone from File Explorer.

2) USB-C cable from laptop to USB-C hub, and then hub to phone; Charges phone, but no data connection.

Is this some kind of USB firmware or BIOS bug? When I plug it into my friend's Carbon X1 with the same cable, it charges fine.

Thanks for the response.

That was the right way to diagnose. 🙂 As you said, if your friend's phone is working fine, we can narrow it down to your phone.

In this case, You may try updating your phone, and then try connecting it.

Let me know. 🙂

Oh, sorry if it was unclear; I charged my phone from her X1 Carbon, which is a Lenovo laptop. So the phone did not have a problem charging from another laptop, which is why I think it's problem with the Spectre rather than the S8.
