MBA13 M3 2024 A3113 EMC8611 820-03285 No Trackpad No Keyboard (water damaged)

[guzq]

Hi Guys,

This Mac come with dead issues (severe water damage), now it’s turning ON except Trackpad and Keyboard not working.

Already check and write down DM for JT400 and JT201 don’t find any abnormal value (I don’t have unit for compare).

Already try,

• Replacing Trackpad Flex Cable
• Replacing New Trackpad
• Replacing Little Board (Daughter Board)
• Try using New Keyboard

Still no change at all, Trackpad and Keyboard not working.

So I check “Power Load Switches” and this is all the numbers,
UC830 > 1 = 3.297V ; 3 =1.757V ; 4 = 3.798V...

Hello, can I ask for help with my problem? I have an HP EliteBook 840 G1 laptop and I have this problem - when I turn on the laptop, it usually starts up to 5-6 times ... the keyboard, power button, LEDs always light up, the fan spins and after 1 second the laptop turns off. After several attempts, the laptop turns on and starts to start, but then CapsLock and NumLock start flashing - 3 times and the fan spins at full speed. According to the manual, this is a RAM error - but I have already tried about 10 working modules and always the same error. Has anyone solved a similar or the same problem?...

Hello!
Today i received a Legion 5 pro with motherboard NM-D562 that suffered water damage, no power at all, no led, no fans, nothing.
I measure 20v on PQ5401 at pins 5, 6, 7 and 8 but 0v at 1, 2, 3 and 4.
Is this normal?
Thanks in advance!

I've been tinkering on Acer A715-43g that had boot issues. Voltage rails are present and keyboard LED lights turns on when power is pressed, but black screen and will not continue to BIOS, I also tried connecting to external diaplay and no activity either. I need to do power cycle at least 10 times to boot the laptop and OS will load. I already changed RAM, CMOS battery and SSD. Can you suggest something I need to look or test next?
