Hi did you solve it ? Have you replace the ddr3L power regulator UP9002p? I have quite similar old board asus x455ld rev 2.1 non nvidia . VDDQ voltage only 0.9 volt. After replacing the Up1565 from donor board, , 1.45V comes out instead of 1.35V . Board started normally but the regulator gets hot and so is the ram coil ....

Hi after 2 years did you solve it?, i have the same problem . Battery not detected on asus x455ld rev 2.1 . I bought this old 2014 laptop with no display, fan spinning fast, orange battery led kept blinking .. the selller said he bought new battery but not detected . i had 5 donor boards exact model. what i did was
replace bios. Display comes up
next i changed bq735 ic . battery terminal only 2.5v instead of 12.56v on normal board.
Next , replaced super io Ene kb9018 A3 from donor boards . Battery detected, batt terminal voltage becomes 12.56v , charging fine, fan spin normal....
