Re: MacBook Pro A2141 820-1700: Missing pp3v3_s5
The trackpad is attached, and the SSD voltage is 2.5 and drops every 1min approximately.
I can be a defective NAND that is not shorted to ground ? If so how can i be sure ?
Thank you in advance...

1.8v with and without battery.
When the battery is plugged, it charges but very slowly, it goes up by 100mA if it can help identify the problem...Leave a comment:

Thank you mon2 for your help.
I’ve already checked logiwiki, but i have all SSD voltages that are supposed to be shorted to ground, but there is no short.
Under thermal camera, the T2 is getting a little hot, no more than 40 degrees celsius. But SSD are cold
What do tou think of replacing U7800 as last thing to try?Leave a comment:

MacBook Pro A2141 820-1700: Missing pp3v3_s5
Hello,
I'm writing this Thread after searching all over the forum and the internet, i can't find a solution, so i need your help.
I have a friend's MacBook Pro A2141 board reference 820-1700, that is supposed to have condensation, because he have it in his backpack while it was raining.
It gets 20v and 0.065 amps on the usbc amp meter.
I have all voltages on SSD, no short on this rails.
PPG3hot is 12.6v.
When i test the boot sequence voltages the first that is missing is the pp3v3_s5 and the line is not shorted.... -
