Hello, I have HP 15-da0053wm laptop, motherboard code LA-G07EP. Can anybody tell me what is this component (K4 VUA, photo attached)? Marking on MB is PQB1.

Re: Name a component
What does the back look like? Is it a QFN-8? post a picture, It might be similar to a E4 dual or single mosfetLast edited by R_J; 05-05-2020, 03:22 PM. -

Re: Name a component
Looks like dual mosfet. No schematic for this board

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
Please also see pictures attached. -
I'm trying to identify a small SOT-package IC marked "XA2LD" located near the 5V_FS rail on a logic board. The silkscreen shows it as U26/U25, and it's adjacent to components labeled R415, C232, L28, etc.
Here’s what I know so far:- The IC marking is XA2LD (possibly custom or abbreviated).
- It’s likely involved in power switching or regulation (possibly a load switch or LDO).
- The package appears to be SOT-23-5 or similar.

Hi,

Hello everyone,
Anyone with a Dell 7330 LA-581P can take a close photo of the bios section as i only have board view ( no available schematic ) and i need to search for the correct values. Please see attachments...02-28-2025, 12:45 PM
