Asus zenbook duo ux481fl not charging

[Scarletb]

Hi ☀️

I have a my Asus zenbook duo ux481fl and I'm trying to see if anyone has the service repair guide? For the physical repair or testing of the battery and ports.

I have the laptop taken apart but the laptop will not power on to check the internal system to pinpoint the problem.

Start with confirming if the power adapter is supplying the ~19v to ground.
