Thanks a million bud.

Under thermal camera, i see nothing getting hot. I know 17mA is not that big for the thermal camera to notice.
Anyway, there's no short.
If anyone knows the BIOS location, please let me.
Thanks folks -

Hi Dear Friend., I am working on a Apple MacBook Pro A2338 820-02773-A. The history was that the AON Rail on the Trackpad connector JT400 was burnt.

I have an Macbook Pro A2338 after small liquid damage, all working fine but keyboard was sticky so I have replaced palmrest for genuine second hand and now lid sensor doesn't recognize when I'm closing the lid. Display is always on, can't find sensor for that model, can someone explain my how does it work, where that flex is if there is any.
Maybe that the motherboard issue, not sure where to start.
Thank You
