Hi @sirdre ,
No video but here’s a link to the [http://h10032.www1.hp.com/ctg/Manual/c05357610|service manual] for your laptop, taken from this [https://support.hp.com/us-en/product/hp-spectre-15-bl000-x360-convertible-pc/13823372/model/13823373/how-to|webpage’s] User guides link
On p.1 it states that the laptop supports up to 16GB of RAM.
On p.25 it shows the procedure to access and remove the memory modules. (see the warning note about updating the BIOS when changing memory).
Hopefully this is of some help.
