Hi everyone, I have a MacBook A2442 with the 820-02098 that frequently restarts during the boot process. When it boots to the start screen, it crashes immediately as soon as I click the setup button on the trackpad (it was restored). The motherboard looks fine. If I boot the motherboard with external peripherals and nothing else connected, the same thing happens. Does anyone know what could be causing this? Thanks in advance.

The board must be cleaned up from the liquid spill. Use ipa (pharmacy grade alcohol with q-tips is recommended) to dab all visible areas. The board is attempting to communicate with someone and timing out and likely rebooting. Try without the trackpad but then the thermal sensors will be missing that are in the trackpad but try as a test.Comment

Hey everyone,
Usually, I'm not the type to ask for help, but this time, I'm calling on your wisdom and expertise
I've seen what this community can do, so I'm pretty sure you guys can help me out.
Here's the deal: I noticed my MacBook got stuck in a boot loop. After opening it up and doing some initial troubleshooting, I found that the boot loop stops only when the trackpad is unplugged.
Now, just so you know, the trackpad actually works — I tested it with another motherboard and it's all good. Same for the cable, no issues there. The problem is only... -
Hello all,
I am repairing a Macbook A2337 and i have a problem
The Macbook is stuck in restore as someone before me tried a DFU restore and bricked the device, now i can't do a restore as AC2 throws error 1 which is related to the trackpad.
When i turn on the device i get the trackpad click for a few moments and then nothing, i tried 7 trackpads and 7 trackpad flats, i know all 7 are functioning okay, especially one as i use it for testing and DFU restore.
I inspected the whole board and everything seems fine.
Can anyone help me as i didn't fiddle with trackpad... -
Hello,
I have been following the posts in the forum for some time now and have learned a lot. I would first like to thank you for this and hope that it will continue for a long time.
I received the MacBook in DFU. The recovery always failed with error 1. After some search, I was able to find a defective inductor (LT202).
After replacing the component, I was able to successfully complete the DFU restore. Unfortunately, the trackpad and keyboard where still without function.
So i measured all voltages and diodereadings on the JT400 connector. ... -
Hi,
I hope this is the correct place to post about this device. I originally posted regarding this on iFixit so see the details from that post below:
"I'm hoping someone can give their opinion on the symptoms I'm seeing before I spend any more time and put money into this. I got this MacBook from a customer and after looking at it they decided they didn't want it.
It doesn't turn on and there's no visual signs of life. I have tried resetting the NVRAM, SMC, power cycling, unplugging the battery, using the charger with the battery unplugged. Removed the... -
Hi! This Mac has been an headscratcher for me, I can't seem to figure out the issue. The Macbook has gotten water damage to the front of the keyboard connector and battery connector. The keyboard connector was dead, by which I mean it was completely corroded and I have replaced it with a brand new one.
I have verified all the pins are connected to the main board and the main voltages (PP1V8_AONSW_KBD_ISNS and PP3V3_AON_KBD_CONN) are both present, with and without keyboard attached.
Unfortunately, the keyboard does NOT want to work, caps lock LED not functioning as well as any...06-16-2025, 12:03 PM
