Hello everyone, I have this Asus model X556UA that when plugged in I get the white light but nothing happens when pressing the power button. I've been looking into it following the power sequence and found out that the power button is sending the signal to the EC (PWR_SW#) but the EC is not sending the PM_PWRBTN# to the PCH (it always stays at 3.3V). I'm stuck here and don't know what else can I do, maybe I can get some help. I've seen that this could mean that the PCH is dead but I don't know how I can confirm this. Also this may not be important but when plugged in, the PCH/CPU (they go together...05-14-2024, 02:10 PM

Hi everyone,
I have been working on a no power issue with my personal ASUS gaming laptop. It went dead a few months ago.
Some history:
Since then, I've found a blown mosfet on the GPU line which I replaced. It started up without a battery, then when I added the battery back it wouldn't start up again.
As a result, there were some blown components around the BQ chip. (The BQ chip itself - BQ24780S, the low side battery mosfet (shorted), and a resistor -> all replaced)
Now, with a new battery the system will start up and run off...05-13-2024, 09:40 AM -

basically the board does not boot and have a rotating cpu/dram led on
all voltages present and everything is in place
nothing burnt nor ripped
except for a strange behaviour (ram rgb is on despite the board not switched on and only have 5vsb present only)
and 5vdual is always present and i don't know why
cpu&ram are fully functional so not doubt about that
any help will be accepted...Today, 09:19 AM
