You're right, I'm returning the board. As I intended it to be my daily driver.

I mean if you thought you only had to replace the charging IC chip only to find out that a trace is broken and knew next to nothing about circuits let alone schematics you would do the same and turn to ChatGPT. I mean 13 days isn't nearly enough to gain the experience and knowledge to diagnose and fix this kind of motherboard repair from zero.

Another correction: The high pitched noise is coming from the charger IC chip.

The other short circuit that I found probing the embedded controller is on a similar 3V rail type +3VA_EC, most of the capacitors or the balls of solder...

How do you think the lifted trace caused the floating track?

Even with the old charging controller it was still shorted and I didn't even get 0.2V at JP8801 until I replaced the charging controller.

I have a spare fx505DY motherboard and can attempt a transplant of that charging IC once I solve the short.

I currently do not have an adjustable bench top power supply, I will purchase one soon. And will try to use electronic freezing spray to track the short.

I am fearing the worst of what to do with the embedded controller since there are none of the same model available.

As stated previously, I only have a couple of weeks experience in attempting any kind of repairs. And had to work with what I had on hand.

I also have the option of returning the motherboard, getting a refund and opting for the 1660ti variant; which I hear is not far in terms of performance...

Correction: JP8801 measures 0.2v.

It's also shorted at +3VA_EC overall, pin 121 of the embedded controller sounds the short....

(If anyone has a functional boardview file of FX505DV/DU that would be helpful)
(Had 3 problems, now just 1)

I have no experience or knowledge and usage of tools to repair devices besides the entire past 12-10 days of researching, watching YouTube repair videos and troubleshooting this laptop motherboard. ChatGPT was used as a guide to ask questions.
I used boardviews of mostly FX505GD-M, and some FX505DU, FX505DD. Used schematics of FX505DU.

I had originally intended to replace the BQ24780s first (due to previous battery removal while benchmarking) but I...
