    Is this jumper wire correct? macbook board missing pad.

    2015 macbook pro which has no sound.

    Noticed some corrosion by the Cirrus audio ic. Resister R6324 had corroded off the board, pad indicated in pic is gone.

    So soldered another 100k resister to the pad closest to the ic and ran a jumper wire as per pic to l6201 for the 3v.

    Is that correct or should i be jumpuring to somewhere else?

      Yes that's fine. Resistor is just a pullup to PP3V3_S0.

      If there is no sound, don't forget to do a PRAM reset to rule that out.

          MacBook Pro Mid-2014 A1398 Retina LED Controller Connector [First Repair (Disaster)]
          by bussincaps
          Hello All,

          tl;dr: minimal electronics experience and my first repair, lifted 8 pads off the laptop display LED controller board when attempting a connector replacement, options are attempting pad repair or jump wiring.

          Laptop Model: MacBook Pro 15 Mid-2014 Retina, A1398 MGXA2LL/A
          eDP Display: Samsung LSN154YL01-A02, assembly sold as Apple part 661-8310
          Soldering Equipment: Hakko FX-888D w/ T-18 tips (Chisel, Conical, Bevel types)

          I needed to replace the 30-pin I-PEX Cabline connector (labeled J8300 in the Apple 820-3662 mainboard schematics),...

          820-00138-A - Advice on how to fix corroded missing / pads
          by mikay786
          Working on this a MacBook i purchased, has some corrosion around what according to the schematic is SSD CURRENT SENSE circuit. I've got 3 missing pads


          The pad left side of R3742, where would be best to run a jumper wire too?

          I assume the other 2 missing pads should be simple enough with top C3701 pad which appears to be connected to the other components on the same plane. Pad on right side of R3742 just need to make sure is connected to trace.

          Mainly struggling with left pad of R3742 and where to run a jumper, maybe a via as appears to go to multiple...

          Macbook Pro Retina 13” 820-3476-A (A1502) - missing PM_SLP_S4_L
          by salopian
          Hello. I would need some advice please.

          My son's MBP suddenly stopped working and is now only getting the green-then-orange light on Magsafe and no fan spin.
          He brought the MBP into the house (22 deg C) from a very cold conservatory (-3 deg C) and turned it on straight away. The Mac suddenly died a few minutes later.

          I examined the logic board and couldn't find any signs of water damage, corrosion, blown up components etc. Nothing was ever spilt on it, and the logic board looks immaculate.

          I have already replaced the logic board with another...

          Apple MacBook A1398 820-00138-A missing 5V
          by mferna14
          HI all, I am working on Apple MacBook A1398 logic board # 820-00138-A. The problem is that it does not turn on & no fan spin. Board is very clean & no sign of liquid spill. Upon checking the initial troubleshooting power rails, I found that its missing 5V (Absolute 0V on the Coil L7720, no pulsing at all, it's just 0V). 3.3V is PERFECT & across all points on the logic board. Checked the IC U7501 pin 4, this pin should have the ENABLE volts to turn on the 5v rail, & P5VS4_EN is missing. This signal generated from U8170 pin 4. PM_SLP_S5_L is also not present & ALL_SYS_PWRGD is...

          MacBook Air 2011 13" >820-3023 A< no power (PLT_RESET_L missing)
          by _Cupa
          Dear community,
          this is my very first post, I am quite new to macbook repairs, and I am excited:-)

          I have a 2011 MacBook Air 13' that does not power on. No fan spin, nothing.

          Here are the specs:

          MacBook Air Mid-2011
          CPU: 1.7 GHz Core i5 (I5-2557M)
          Model: A1369 (EMC 2469)
          RAM: 4 GB
          VRAM: 384 MB


          The first question:
          Unfortunately, it came with a 'fake' power adapter which seems not to talk to the computer. Sometimes it does show green light immediately after connecting it to the board,...
