Check whether DRAMRST#/PLTRST#/All_SYS_Pwr_GD is present or not.

Check whether DRAMRST#/PLTRST#/All_SYS_Pwr_GD is present or not.

DRAMRST# =1.3v
PLTRST# = 3.4v
SYS_PWROK/All_SYS_Pwr_GD = 3.2v

all present

here is the bios dump

For better organization of this website, post the bios in the bios forum and link it here.

Connect a usb keyboard and see if numlock light glows on it or not. It seems motherboard is posting but may be no internal display. Confirm whether its posting or not?

i use a usb stick that have a activity led its not communicating. i got it to work with random BIOS it posted after multiple attempt then i tried CLEANING ME + NEW BIOS REGION + Transfer (UUID,SN,windows KEY) it booted again but when i tried to restart it freeze and no display again then itried to reflash again the CLEAN ME BIOS still no display.

maybe EC BIOS got corrupted?? or dead CPU?? but the sys_PWR = present

so it turns out that the (GPU + VRAM) is causing this no display converted it from DISCRETE to UMA by removing (+1.35V_GFX and +VGPU_CORE) Circuit

it boots fine now. thank you.

The symptoms does indicate me to a dying SOC perhaps. I dont think EC bios is corrupt.
