thanks brother... -
hey man ! HRU ?
i need yr help with my issue , seems like my MB is dead. How i can fix it ?... -
Hi I manage to solve this issue. After testing all the voltage found out its all normal.
It wasn't a bios problem also because I tried so many versions, even my back-up doesn't work.
So i have a hunch that it maybe a cold solder.
So I reball/resolder the 1.8v regulator since this is the one overheating. I also refresh the solder of the legs of the SIO and that is all. It works.

Not yet. Still waiting for some inputs by the other members here. Its hard diagnosing without schematics. I dont want to guess and cause more damage to the motherboard. Hope someone can give thier expertise....Leave a comment:

Re: HP Omen 16 no display
Hi here is the measurement at 200 ohms range on multimeter.
Ground to ground resistance is 2.2 ohms.

Re: HP Omen 16 no display
Great, thanks Sir for the explanation.
So I will focus on the load maybe there is problem there.
If this is a 1.8v pch power ic, is it possible the pch is faulty?
Or anything somewhere after the inductor?
I will check this and post update....Leave a comment:

Re: HP Omen 16 no display
Hi, I already measure the resistance to ground posted above this comment.
Im sorry maybe we have different understanding or terms on what is a "load" means. Maybe load has different meaning in my language
. Can you point me to the right direction where is the load your are referring to or what pin in this buck converter?
I ask if it is safe to run the board without this IC because it is only my wild imagination to further test the voltages around this circuit, its hard without schematics to follow....Leave a comment:

Re: HP Omen 16 no display
thanks Sir, could this be a good replacement? I'm not sure yet because there is no schematics of the board but looking at the physical pins, they look the same. I will check the pin configuration manually if they are the same....Last edited by fhulgzz; 09-06-2023, 06:13 PM.Leave a comment:

HP Omen 16 no display
Hi I need help, I hope someone can help me.
Model: Omen 16 B0080TX
Board Code: DA0G3KMBCG0 REV:G
I have a hard time diagnosing because there is no schematics/boardview available yet, if you have, please share.
