How to contact HP support when HP support page isn't recognizing serial number?

[Justletmeread11]

Hi

I tried to check warranty status. Entered serial number, ended with "Please enter a valid serial number"
Tried to contact HP support to get explanation, and every time I'm going through questions, at the end forcing me to choose one of the devices on the account or to add a new one. Which always end with "Please enter a valid serial number"
Real life Paragraph 22. 

How to solve the issue?

Hi @Justletmeread11,

Welcome to the HP Support Community. 

I'd be happy to help you! 

To be able to answer you effectively, we need some information.

May I have the exact product name and Serial number? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc.

Registered here just to post this. Your Product Registration (https://www.register.hp.com/) page is broke. You input all the information and try to press the SEND button, but it does absolutely nothing. Confirmed this on 3 different browsers and 3 different computers. I need to Register a product.

As as the OP mentioned, I can't even get to the proper Contact HP info because the Serial number input to do so is also broken.

Hi

It's HP ProBook x360 435 G7
We have handful of these and none of its serial works on your page, ending with error:

In terms of providing serial number - you're asking for it and then a line below warning not to share any details like serial numbers...

Are we going to get a reply about this?
