All hp omen 16 2023 unit have faulty motherboard

[Unmanned46]

Same thing happened with my laptop. Since it is in warranty I am getting laptop's motherboard replaced

But I have the amd and it’s happening to me. Using a magnet to turn it on 😪

I think, I have the same issue but I am not sure if the placement of the hall sensor cable is the same in mine. my model is OMEN by HP Gaming Laptop 16-xf0xxx

Omen 16-n0033dx Win 11 same issue, now the second time in 17 months of ownership.

Warranty is expired and quoted HP repair cost is $541.86 USD. Motherboard was replaced almost exactly one year ago and the intermittent overheating and black screen problem has reoccurred.

Can someone tell me what is actually going on with this motherboard? What is the root cause in the AMD variant? I cannot justify a mobo replacement every 5-12 months on a high end laptop. I have seen statements of failing hall sensors and capacitors, but nothing specific to the AMD board.

Thanks

Hello im the op post on this hp forum like i said the only thing you can do is disconnect the ribbon cable that regulates the sleep just disconnect the ribbon cable like i said. Search on reddit for my popular post. Hp omen 16 2023 black screen issue post to help others. On reddit

Your post was specific to Intel MB's, mine is AMD.

Guys, My laptop specs: AMD Ryzen 7 7840 HS, Rtx 4060 (HP omen 16 . I faced the same issue.

what I did is 
1) Called Hp service guy to home (if you are still in warranty period).
2) Asked the person to remove the ribbon cable but he refused and didn't acknowledge, after replacing heatsink and thermal paste, the issue was still there.
3) after insisting, he unplugged the ribbon cable, and the issue was gone.
It doesn't matter if you have an Intel or AMD motherboard—just unplugging the ribbon cable seems to fix it.
Got free replacement of heatsink with no charge at all. 😅 and he did some cleaning.
Currently playing Indiana Jones at 60+fps Ultra settings except the textures at medium since the 4060 has 8bg vram.😑

No problem glad my post have helped a lot of people on hp forum and on reddit

I have read that the AMD variant, has the hall sensor in a different location on the MOBO, that is away from the heatsink. I am also experiencing some overheating in addition to the black screens. I am curious as to what the post on reddit was from some engineer, that claimed that the responsible components of the overheating, are a cap and an inductor, but he does not elaborate on which ones. I also think that if a bad hall sensor is responsible for the black screens, why not replace the hall sensor? From what I saw, it looks like the sensor is on a flex cable/zif socket. 

It just seems to me that all of this stuff I read, just doesn't have enough info to be gospel and I need more.

Thanks

As said before, due to some bad decision of some HP engineer, the sensor (which is responsible to know if the lid is closed or open) was placed in a very bad position, somewhere close to parts of the laptop that heat up a lot. So pretty soon (while giving the laptops gpu and cpu a good challenge) the sensor will die because it's not made to be heated up like that.

As this topic shows, it's not very different if you have intel or amd (mine is intel and got the same trouble a while ago). The difference may be in a place where that sensor is connected to the motherboard, so it is where you can unplug it.

What is actually happening:

Sensor dies while you're using it and starts thinking that the lid is always closed, so it turns itself off and doesn't let you turn on the laptop anymore. The laptop just thinks that the lid is closed and there is something stuck on top of the power-button that pressed it, while closed. Logically you're not supposed to be pressing that button if lid is closed. So that's a way of life for the laptop from now on.

What i did to fix this:

1. Found that connector somewhere on centre-right side of the top part of the motherboard and unplugged it. So now laptop will not know if the lid is closed or open, so it just thinks that it is always open.

2. Turn on the laptop. Enjoy the power of it again (probably not buying HP again thoooo)

3. Adjust the cooling control to keep it more cool.

Positive side of this solution: basically everything works fine.

Negative side: if you just close the lid, laptop will not know that you did that and will just remain on until the timer of "go-to-sleep-if-inactive-during-5-min" will send it to sleeping mode. So from now you turn it off or send it to the sleeping mode manually before closing the lid.
