    HP Pavillion 15-p290nb power faillure

    Hello dear friends.
    I own a laptop HP Pavillion 15-P290nb.
    The power plug has failed mechanically and I have replaced it with a new one (HP DC in cable 65W / 90W HP p / n 730932-yd1 Rev: x2.
    After repair, the laptop still did not work.
    No LED fire up. The voltage of 19.5 Vdc is present on the connector on the motherboard.
    Can someone tell me what the component is between connector and ethernet connection on the motherboard.
    Motherboard type: DAY16EMB8C0 Rev-C.
    Does anyone have a technical schedule for this motherboard?
    Attached a photo of the component and of the motherboard.
    All info is welcome.
    Thanks in advance.

      Then check 3.3V_LDO and 5V_LDO first.

              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:

              After updating motherboard capacitors, what to do next (Asrock K7VT2, SOLTEK SL-75FRN2L)
              by dragon3x
              Hi, I have some 32 bits computer motherboards that need repair, as they fail to
              power on.

              Here are some examples :

              (N.B. "capacitors" indicated here are electrolytic capacitors located in the onboard
              switching supply area).
              (N.B. #2 : I could not find a 3300 microF aluminum-polymer with a higher voltage
              than 6.3 V.)

              1 - Motherboard #1 : this is an Asrock K7VT2 (socket A) that still works well. To put it on test
              I replaced capacitors with aluminum-polymer.
              3300 microF/6.3 V. x 4 replaced by 3300 microF/6.3 V. (KYOCERA...
