I am working on a Apple MacBook Air 1466 820-3437-B logic board. There was a slight liquid spill near the L7095 coil on the PP3V42_G3H rail. Cleaned it well, now it turns on fine, fan spin is normal, I see the folder, display is perfect. Now the issue is that when I install the SSD, the logic board turn on, fan spin all the time without the normal check (Fan spin, stops, again spin then stops & then fan spin continously & the logic board start to work normal). & there is no display at all. I checked the SSD on another good unit, its 100% fine, but on this unit it gives this error. I checked the main power rails, all seem to be fine. Does anyone know what be causing this abnormal behavior? thanks

Re: MacBook Air 1466 820-3437-B abnormal behavior
So when there is an SSD inserted in this machine it doesn't POST? Do you have another SSD to try?
Can it boot properly on an external drive?
You can try to run ASD too.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView -
Re: MacBook Air 1466 820-3437-B abnormal behavior
Yes when SSD is inserted, no post at all... I tried with another SSD, still the same... but surely can try with external HDD.. From where will I get the ASD for this Air?? is it on the net??Comment

Have you checked the ssd port (inside) on the motherboard or the pins of it for corrosion ?Comment

Hi everyone!
I have a 2018 MacBook Pro (with Sequoia OS) that I've been using for years with no problem. I recently received an M2 MacBook Pro so I'm mostly using it and not the 2018 one, but since a friend of mine needs a computer, I thought I could restore my 2018 and give it brand-new-like to my friend.
I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...06-27-2025, 08:54 AM -
HELLO FELLOW COLLECTORS, How are you doing, I hope GOD always gives us good health, I'm here asking for help to work on this MacBook Air, to be honest, this is the first time I'm dealing with a MacBook machine, and I immediately decided that the ISL 6259 IC and after I replaced it it still didn't work and I found that the CHGR_CSO_N & CHGR_CSO_P pins had a short circuit.
can anyone help me guys? -

Hi, I have this Macbook Pro A1706 [820-00239] with an abnormal fan spin [or quarter fan spin according to LOUIS ROSSMANN]. The laptop boots up normally and performs normally besides the fan's sound which only starts to happen when the laptop starts getting warm as a result of it being used.
I have replaced fan, reset SMC and PRAM, reinstalled different MacOS versions but same problem. It is the LEFT FAN.
Any idea what could be the cause and solution for it... -
Hi
MacBook AIR 1466
MB: 820-00165-A
I followed the power scheme https://logi.wiki/images/a/af/G3_-_S...ell.drawio.png. I have all voltages up to "PM_SLP_S5_L" = 0V. When I plug the charger it tries to power on, goes to 0,250A then goes to 0,023A and does nothing. No fan spin.
I'm confused, board looks good under microscope. No corrosion.
