Hello,
Any ideas what to check on rx580 which has all voltages present but is not detected?
Thanks!

Re: Asus UX31E rev 3.2
CPUPWRGD and VGFX are still 0v
Edit: CPUPWRGD is 3.3v for half a second and then 0V for few, same for Vcore. VGFX iz 0 all the time.Last edited by dvorel; 08-31-2021, 08:35 AM.Leave a comment:

Re: Asus UX31E rev 3.2
I did go through that with no luck..
1) PL8005 resistance on #2 to GND 15.2ohm
2) No, Vcore is only 0.1V
3) I think shorted mosfet would pull Vcore to GND or to 19V, and that is not happening here
EDIT: Found that PR8076 was high value, replaced It and now I'm getting Vcore around 1.1V but motherboard still doesnt turn on...Last edited by dvorel; 08-31-2021, 05:43 AM.Leave a comment:

Re: Asus UX31E rev 3.2
Hi,
Yes my power adapter is fine, stable 19V.
There is repair guide and boardview file for this board, I uploaded it to attachments.
Vcore only gets to 0.1V, and VRM_PWRGD is 0 to 0.1 volts also, H_CPUPWRGD is 1.05V.
No liquid damage is present, board just wont turn on.
A: 0.9V on PL8700...Last edited by dvorel; 08-31-2021, 04:55 AM.Leave a comment:

Re: Asus UX31E rev 3.2
Here are the measurements.
PL8200 -> 32.2ohm
PL8003 -> 15.5ohm
PL8700 -> 54.8ohm
PL8005 -> 17.2ohm
And the rest (above 200ohm).
PL8800 -> 150kohm and going up
PL8100 -> 9.5kohm
PL8101 -> 5.6kohm
PL8301 -> 460ohm...Leave a comment:

Asus UX31E rev 3.2
Hello,
I have issue with ux31e, after pluging charger in power, caps and f2 lights come on and off in intervals. I measured all voltages are fine except VRM PWRGD, it jumps from .1V to zero in same intervals. Vcore gets to 0.1v also and GFX core stays at 0v.
I did try to reflash bios but everything is same after it.
Thanks for your help! -
