Hello there I need help identifying this components, one of this is probably shorted, because it has low impedance measuring coil from vout to GND, I suspect it might be 5 or 3v but not sure, I don't find any references to this marking codes. If someone has any info please let me know. DFAF JB, CUHF JC. It is from a HP Victus laptop DDR5 CPU AMD. There are no schematics or boardviews for this model, and no datasheet. I read something this chips were proprietary manufactured ๐คท๐ปโโ๏ธ. Cannot find even where to buy it ๐.

Thanks mate, is there any available schematics where I can see sy8371b?? There is little info about that chip and is the one I think is shorted, I think is 3v railComment

The datasheet is here https://www.silergy.com/productsview/SY21246BTMC .That might look like the wrong part number/datasheet but it isn`t, silergy have started using a different part number called a Global part # ,it can be a bit confusing.

Hi,
I am working on a Surface Laptop GO 3, which is the new release 2024 with a i5-1230U processor. Originally, it had a 256GB SSD, then the owner attempted to upgrade it to 1TB SSD by himself. "Surprisingly", it did not boot afterwards, then changed back to the original SSD, did not boot either.
It turned out to be that just a couple of components had been knocked off when the owner was trying to get off the SSD cover with his beloved screw driver.
I do not have another board of same model. Although I have a Laptop Go 2, the layout of that bit...04-29-2025, 04:13 PM -
Dear BadCaps colleagues,
I'm working on a HP Omen 16-WF0894ND. Won't turn on. Battery is charging and 3 and 5V rails are present.
However, I located PU1801 that's only outputting 0.37v as soon as the power button is pressed. Weird voltage imo, although there's no short after the coil. Chip aint getting hot either. Since no diagram is available, I can't really determine what this rail is for, but I assume it might be a PCH PWR rail. Please help me to identify:
Chip marking eHFFH
Board model: LA-M783P

Huawei D14 dah98ambad0 rev d please help identify Missing components
Hello I just bought this laptop to be used personally (that I'm currently trying to repair.), I am aware that liquid (gravy) has been spilled in this area before. but there are missing components it it possible to have a board view or a schematic of this? or just an idea on what components its missing?
as far as I know this parts are connected as sense or enable.... that's how far I know...
Images attached:
the picture of the area. and some of the pinouts that I noticed on the chip... -
Can someone please help me identify this part? It's from an HP Victus 16-Sxxxx notebook." Let me know if you want a more formal or technical version.... -
Hi guys,
I need some help to identify this burnt components of the GPU as per attachment.
FYI this is the GPU spec:
https://www.techpowerup.com/gpu-spec...cu-ii-oc.b2130
I have the boardview but it does not provide the parts number etc.
Does anyone have any info on this part of the circuit?
Many thanks.
