I think could we ignore the signal ME_AC_PRESENT. Just go to check signal 1.5_ON, might be that signal was present after you pressing power button. If yes, then check on Low side mosfet on block 1.5 (pin 4 PQ8301/pin 15 PU8300). Because signal En for controller 1.5VO coming not from SUSC signal. Just guessing, maybe this point was clue the problem.
signal 1.5_ON is not present.
SIO generates RSMRST and 3v_SUS_ON and other signals after pressing the power button.
should be they generated after plugging adapter in before pressing the power button?
I do not know why PM_SUSC is not generated by PCH.
In this laptop, BIOS chip is connected to SIO. SIO reads BIOS, but PCH does not.
Does PCH read BIOS before generating PM_SUSC?
I need Bios for Asus D452V Laptop.
mainboard model: X450VP REV. 2.1
note1: my original bios in post 1 and 2 are probably damaged, because I tested them and got no result.
note2: I already got bios of mainboard x450cc rev2.1. I tested it. It was good considering SIO but PCH does not turn on. I downloaded it from this thread: https://www.badcaps.net/forum/showpo...13&postcount=2
I carefully looked at the markings on the laptop. I realized that laptop model is Asus X452CP. So I appreciate if someone uploads bios dump for this laptop:
Laptop model: Asus X452CP
Mainboard model: X450VP REV. 2.1
the original dump is in the first post that does not work.
