Hi. Recently serviced a damaged A1466 Macbook Air. Thought to post the issues and resolution for each.

Macbook AIR Model A1466 Diagnostic 09-01-2021

Issue: Liquid damaged (beer spill) Macbook AIR will not power up.


Problems & Resolutions

1) Attached Apple magsafe power adapter. No green / no orange light. This confirms the absence of the PP3V42_G3H voltage rail. The PP3V42_G3H rail is the primary voltage rail necessary to communicate with the magsafe power adapter to report the green or orange light status to the end user....

Hi,
I am trying to fix this liquid damaged 2020 Macbook pro and I noticed something weird.
When I push on/around the renesas 501cr0b IC, which appears to be a clock generator/ multiplier, If I apply lot of pressure, the device will reach 19.9 volts and seems to be trying to work.
I have thoroughly reflowed that area and completely removed that chip (there was some liquid stain in that area) but no help. I have just 5v 0a unless I apply the pressure.
Your help is GREATLY appreciated. Thanks!

Hello everyone,
I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.

I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A

My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.

And the resistor L4004 is literally burned.

From what I see from the schematics, it does not affect any other rails, only the connection to the display...

Hi, does anyone perhaps have the boardview schematic for an Apple Macbook Pro 2024 M4 A3401? Many thanks in advance. (I managed to find M3, but there are differences in the board layout)

Hi everyone.
Macbook Air A1466 EMC 3178 (board 820-00165 A) not turning on and no charging light. Completely dead. With no battery connected it would power up and I could hear the chime, but nothing on the screen and then a sudden turn off. Sometimes during the chime. Opened it up and found some liquid damage. The flat that connects both boards has damage in one side (with a missing pin already). The connectors on the boards are fine, though.
Also, there was liquid damage on the included picture area, which are R8111 and C8111. A quick and soft brush on it made the resistor be gone....
