ID:	3547554 Hi.
    Can you help me? The boardview of the DA0G3DMBCE0 REV:E motherboard says that the PU401 IC is a MP86903C...however this is a TQFN21. The PU401 is a TQFN13 and the MP86901-AGQT-Z IC is TQFN13.
    Am I correct? Or is it a different IC?
    I would appreciate an answer.
    Regards.

    Do you have the original part from this motherboard? Post clear pics of the PCB where this part was originally mounted.

    My bv file also reports the part to be MP86903C. If you have the original part, post top and bottom side clear pics of the part for a review.

      Hi.
      Thank you for your reply.
      The chip is quite damaged although some letters and numbers can be seen. I think it indicates AMVJ 944.​

        Good catch! The boardview is wrong.

        The part on your board is indeed MP86901-AGQT-Z​. The topside markings on the replacement should also bear the same first 3 markings of ‘AMV’.

              Component on Hp probook 440 G6 motherboard DAX8JMB16E0 REVE
              by eemeren
              Hello,
              By mistake I think I made a shortcut via the USB connector and my Hp probook 440 G6 does not startup anymore.
              A component on the motherboard DAX8JMB16E0 REVE is fried.
              Does anybody know the component number?
              thanks, Johan

              Asus ROG Strix Scar G533qm with a G733qm Motherboard, can I modify the Bios to accept G533 Bios
              by glovecaps
              Hello,

              I have a Asus ROG Strix Scar 15 (G533QM) that had a dead motherboard (Graphics card dead) and after trying to fix the motherboard with no success, I bit the bullet on a sale for a new motherboard. I ordered a motherboard for the 15 inch model which is the one that I have, and when the motherboard arrived it wasn't for a little while that I saw it was from the 17 inch model.

              My question is, can I update the Bios on this G733 motherboard to a G533 Bios.

              The reason for wanting to do this is that the keyboard isn't working as it should, and I think this...

              Legion Y540 17irh motherboard issue ( need help to know how to diagnose my motherboard)
              by Docus
              Hi everyone 😀,

              I'm here today to ask for help with repairing the motherboard of a Lenovo Legion Y540 17IRH.

              To give you some context, I'm passionate about computer repair so much so that I've invested in a lot of tools and started practicing on dead and old hardware. I've been learning how to solder and desolder components, mostly focusing on phone repairs.

              Recently, I bought a broken Lenovo Legion Y540 17IRH for just €150, and there are two main reasons why I made this purchase:
              1. I already own the exact same model, but its plastic chassis is badly damaged.

              HP Envy 17-3290NR 3D Blank Screen - motherboard Louis V1.1 6050A2489901
              by Archimedes
              Subject is a blank screen issue in HP Envy 17-3290NR 3D version laptop with motherboard Louis V1.1 6050A2489901 MB-A02. Production year is 2012. This one is a 2nd hand motherboard which I could use it for few months only. Suddenly no output from the internal display and also no signal from HDMI port then Windows out of order after few boots.

              Caps lock working normally and no HP's caps-lock warning blinks. Making a hard reset and replacing the RAM sticks or using different slots didn't help.

              Fans are spinning. Blindly could install windows11 and got the device manager...

              ASUS P5GC-MX motherboard recap
              by momaka
              Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
              This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.

              So here is what the motherboard looked like with its original caps:
