I see, thanks for that info, also I didn't check that the resistance on Vcore is low, I was thinking it has a high Z, one of the MOSFET is shorted so now I'm checking that to replace them and also fix the q510 got a destroyed via... -
Gigabyte 1660 Super OC 12V Short 8pin connector
Hello i got a card with 12V short, found an IC blown Q510, remove it short persist, found that the short is on 12V GPU, remove all the Mosfets and the short still there, i inject 1.5V to the line and i got 1A of consumption, nothing getting warm, this could be the GPU itself?... -
Its going to be on the order of K OhmsLeave a comment:

With that info on the caps i can see you have a short on VSYS15, you can start desoldering one side of PL405, and measure on what terminal de short remains, if the short is on terminal 1 then you have a problem in other side of the board (Maybe you can focus on the part of PQ101), and if remains on terminal 2, then could be the IC PU404Leave a comment:

Oh you can check the reference of those caps you removed? i cant see it on the pictureLeave a comment:

Yeah i can check in a couple of hours but yes its a clue, depend where the caps are connect you can check what via it is in the schematic and trace itLeave a comment:

You can have the tensions but if it has low impedance on some rail. they gonna consume more power, first i would measure that.Leave a comment:

Sounds like a short to me, try to measure resistence on Mosfet, mostly the problem is that.Leave a comment:

You can check if the 5V IC has the enable pin activated....Leave a comment:

The mb is Laduree 1.0 MB 14257-2 doesnt has discrete graphics card, just the CPU BGA.

HP Envy X360 Image distorsion
Hello, first this is my first post so if i did something wrong tell me!
I recently bought a faulty Hp Envy m6-w101dx, no image, when i turn on its loaded with Windows 11 and it was working a few minutes then it got vertical lines, distorsion and then the screen goes black, and never come back unless i power it off and then on. I try external HDMI but no image, i opened up and i found HDMI IC burned, i measure impedance, voltages and nothing out of normal.
I loaded windows 10 and goes worst i just can enter on login screen and then the distorsion comes, on safe mode i... -
