My friend has the HP Pavilion x360 - 14-cd0053tx laptop : HP Store - HP Pavilion x360 - 14-cd0053tx
The HP support page mentions that the RAM is upgradable to 12GB.

Memory 8 GB DDR4-2400 SDRAM (1 x 8 GB), 2 SODIMM Slots (upgradeable to 12 GB)

Currently it has 8GB RAM in the first slot.
Since the second slot is empty, should it be possible to install another 8GB RAM in the second slot? Making it 16 GB.

Then, why does the HP page say that it is only upgradable to 12 GB?
It seems a bit odd to me that HP says we can only install 4GB RAM in the second slot, when it already had 8GB in the first slot.
Any explanation for this?

Need to decide if we should buy a 4GB RAM stick or 8GB..

Here is a video showing the insides of the same laptop with two slots and 8 GB in the first slot: YouTube - RAM Upgrade HP Pavilion X360 2018| cd053TX
