Laptop Type-C full function or fake?

[Parth2105]

I have an HP-14s-dr2006TU laptop. HP says it has a USB-C Gen1 data only port (USB-C which can only transfer data with max cap of 5Gbps). But now I look at the contacts and it looks like a full function USB-C with all contacts, compared to my phone's port in which a bunch of the contacts are non-existing. So am I being trolled by HP or is it really a full function USB-C or did I made a mistake?

What sort of functionality your looking for?

It says DATA ONLY, so i'm assuming no charging & no display.

A usb-c ports can have all the contacts, doesn't mean it will use all of them.

So they never ran the traces is what you are saying? Well I am under warranty so I am not really willing to open it up for board shots. Thanks anyway.

 

P.S. Yes since it says data only, it does not support charging and display. Also I was comparing the presence of contacts to a oneplus 6 usb-c port which does not have all of the contacts.

Yes, you don't need to wire all the contact, it's up to the manufacturer to do this, especially if the motherboard or cpu doesn't support the functionallity.

The CPU is tiger lake and has thunderbolt 4 support. But I tested the charging capability and yep, no luck. Thanks for responding.

Adding thunderbolt support is additional cost.

TB needs a controller on the motherboard, so to cut the price down, they skip this feature.

USB-C and Thunderbolt are different things. USB-C is just a port, any number of things can run over it like USB-3, USB-PD (laptop charging), display port or Thunderbolt.

 

Thunderbolt 3 is 40Gbit, so it looks like that port doesn’t support it. Thunderbolt also doesn’t include anything beyond 15W for power, similar limitations exist in the USB spec. You need USB-PD over the USB-C port for laptop charging which... unfortunately, again seems like your port doesn’t support.

 

It’s a convoluted mess of a port, I know.

Thanks, I now know.
