Cannot Identify HP laptop in order to upgrade RAM

[Gaz58]

I have a laptop here that that I have been requested to upgrade the RAM, so I naturally used the HP site to scan and detect the product. Unfortunately the print on the underside of the device is unreadable and when I use the Serial Number, I am told that the process for this laptop needs me to enter the Product Number as well. I have used 2 CMD commands, one produces nothing the other the Windows key and an App I downloaded from MS Store which installed, apparently, but I can't find to run !!! HPs system information App returns a Product Number but it doesn't work on their site, so all I have is the basic information that I've found on the inside of the  bottom case, which is HP 250 G9.

If I use MrMemory.co.uk to scan the laptop, it tells me it is a HP 250 15.6 inch G9 Notebook PC, but it fails to find any RAM compatible, but I think this is due to a typo on their site. If I search for HP NOTEBOOK 250 G9 it tells me the maximum RAM is 32Gb. 

If I Google HP 250 G9 MEMORY UPGRADE then memorystock.com tells me it will take 64Gb.

Kinsgstonmemoryshop.co.uk tells me there is only 1 RAM slot and the most it will take is 8Gb ... well it already has 8 Gb in BOTH slots !!!

Does anyone know which of these, if any, is correct ?!?

If the notebook has an Intel core processor, it has two memory slots and can support up to 2 x 16 GB of DDR4-3200 CL22 memory.

See chapter 1 of the service manual for the memory upgrade info:

Maintenance and Service Guide (hp.com)

The notebooks with the Pentium Silver and Celeron processors have one memory slot.
