HP x360 Sphinx Battery Fix

[JAM_PT]

I have had my ENVY x360 - 15 dr0008np for a time and I have always had the issue of battery drain while the laptop was shut down (100% to 87% overnight). I did not pay much attention to it as I mostly charged my laptop overnight. Now that I use my laptop more often, it has become a burden. After searching on the forums, many users of the same laptop model reported experiencing the same issue and have "fixed" it using the sphinx fix that HP apparently posted. However, I could not find a link to the patch despite searching through every thread about the topic. (example of forum thread) I was wondering if any HP reps still had access to the sphinx fix or if any users of the forum knew where to find it.

Thanks in advance.

I have already ran the battery diagnostic tool and have no issues with the battery itself
I have installed all updates in HP Support Assistant
I have upgraded BIOS

Apparently I have been able to fix this, as the laptop stop draining battery when turned off for a few days now. 

What i did was disabled Intel Management Engine Interface, under device manager -> system devices
