    First motherboard repair, which device?

    I've learned many things through own research. However, repairing motherboards with only basic electronics knowledge has been more challenging than I thought. I've given up many times but I am on the verge of another attempt and I need your advice.

    I have two devices here and I wonder which one would be best for a newbie
    • MacBook Air motherboard (part no.: 820-000165) orange light on charger, no pwr, no fan
    • Or an iPhone 6S no power, not even with new battery


    (Other device tips are also welcome but these two I have at hand)

      fone is probably the charge/power chip - i think it's TriStar on those.

      for the macbook, luis rossmann has a big pdf about fixing those that lists all the faults/symptoms

          Right! The TriStar chip is quite challenging to solder right?

                  ASUS TUF Dash Motherboard FX516 REV 6.0 Model Device Not Charging
                  by lazenes
                  The device is not charging with the 19V 180W DC charger. If the battery is full, the laptop powers on normally. I can charge it via USB Type-C, but it’s very slow. I checked the schematics but couldn’t find a solution. I even replaced the BQ24800 battery charging IC, but the issue remains the same. I suspect a MOSFET or a fuse that I might be overlooking is preventing it from charging with the adapter. Has anyone experienced a similar fault before or has any advice?...

                  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.
                  ...

                  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...

                  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:
