Upgrade RAM memory

[Quantumturbo]

Can you tell me how many slots of RAM my HP Spectre x360 Convertible 15-bl1XX has and what is the standard configuration that is shipped? I beleive I have 8GB of RAM and would like to upgrade to 16GB at least so your recommendations please for RAM upgrades.

I've tried to do a UK Crucial memory check and I can't  seem to find my model number in the options available. Again my PC  says it's HP Spectre x360 Convertible 15-bl1XX. Are there other model numbers I should use?
