ASUS GA401IH ASUS ROG Zephyrus G14 does not power off

[tonycstech]

Laptop was hit by a lightning.
Killed 1.8v, CPU, BIOS, embedded controller.
Fixed everything.
Laptop powered, works 99.9%>

Pressing power button ONCE does not turn it off.
I have to press it for 2 seconds and let go, then it will go into normal shutdown process.
If i hold it any longer, it will go into FORCED shutdown as expected.

I replaced the button, no change.
Replaced U3201 power switch/reset logic SLG4E42553VTR no change.
Anything else that can cause issues like that ?
Perhaps BIOS is not legit ? I dont have any other bios.

Can you shut it down properly from windows?

[tonycstech]

Behavior is the same in BIOS, LINUX or WINDOWS

Confirm that the power button has the required pull-up resistor @ R3019. When the power button is not pressed, what is the voltage on PWR_SW#?

From where was the U3201 sourced? Donor board? Silego are effectively low density FPGA / CPLD devices and code must be injected into the component to make them perform like a state machine. For this reason, donor boards are most likely the only option for this component.

U3201 was brand new. It got flashed as soon laptop powered.
I believe asus has a section in the bios dedicated for flashing this Embedded controller as soon as it boots when its blank.
So my next question is: how to reset the EC so it would reflash its self ?
Otherwise i have to buy blank chip or buy vetryanov programmer for hundreds of dollars to flash it manually.

I am reading 3.3v before and after R3019

buy svod4 it has 128pins and bga adapter for sio such as ite and ene .. it is better to brush the bios and flash the new ec to make sure

Perhaps nothing to do with bios and EC firmware.
Try removing ethernet/sound/wifi one by one and see if you can shutdown properly.
If problem persists after these steps, then proceed to check whether the enable for 3VS/5VS dc-dc transfer ic is removed on shotdown or not?
If the enable is not removed for dc-dc transfer,then replace this dc-dc IC.
If power button is on keybaord, try without kbd.

Just ordered one.
Is there a tutorial how to deal with ASUS bios and extracting part for the EC ?

PCB by its self without anything connected does same thing. Most likely EC firmware at this point.
There are no timing caps in circuit that i could suspect to cause issues so.........
Will see.
