Hello, I have a big problem with an HP computer with the epv51 la-g078p board, above the chip only the letters 8ieaqd appear and in BOARDVIEW it is identified as PU301, this component has shorted out and I am unable to find the replacement or the reference to be able to replace it, can someone help me? Thank you very much.

Do you have the schematic for the board? Usually the board view files include the schematic in pdf format. If so, look for the part identifier and it will tell you what the part is and the value. From the PU designation, I would guess it’s a pull up resistor on the power-up rail, but that’s only a guess. -
What are the top markings on the ic? Post a clear picture of the ic
It might be a SY8286BRAC QFN20 marked AWVxyzLast edited by R_J; 10-10-2024, 07:40 PM.Comment

It is next to the ENEAttached FilesComment

Clear as mud.
What about BIExyz?

It seems so! THANK YOU VERY MUCHComment

I'm back to my old ways, after changing the component (SY8286B) sometimes it sends the 3.3v signal through pin 17 and when it feels like it stops feeding the equipment and turns off, can someone tell me what could be happening? The ENE was also changed and everything was reprogrammed, thanksComment

Good morning, I would appreciate help identifying resistors responsible probably for volume down / volume up buttons that I accidently knocked off while replacing fan connector. I enclose picture with location. Thank you for help in advance.Today, 01:49 AM -
I need help identifying this IC and, if possible, the value of the capacitors next to it. It is part of the HDMI circuit of an EVGA RTX 2060 GPU. It suffered a short circuit, leaving the graphics card without video and the TV without image....06-06-2025, 07:48 PM -
Subject: Help Identifying IC on 820-02020 (MacBook Pro A2338 M1, 2020) — C02045500 / EKQ8LL1A
Hi all,
I'm working on a MacBook Pro A2338 M1 (2020) with logic board 820-02020.
The machine has a power issue — not powering on, and I'm trying to trace the fault.
While inspecting the board, I found a cluster of components
This area looks damaged or burned — there are about 4–5 components that seem affected
I've attached a close-up photo of the chip and its surrounding area (see... -
Hi everyone
I have a 70mai Dash Cam A510 which failed after about 3 months of being installed in my car, likely due to heat, i got it from aliexpress so no point in trying to return it for warranty (and shipping it back would cost me almost the same as a new one from ali)
The camera would boot loop showing 70mai logo on the screen, sometimes it would boot fine then the live view would freeze or display purple lines
I already took it apart, and found out that the camera boots fine if i unplug the camera module from the main PCB, sometimes "playing" with the connector... -
I am having trouble identifying this chip, it's near where the power comes into the board. From a HP Victus 15. Says RW=AL UG1
