Hi R7071 is fine SMC_BC_ACOK is 3.37v I have a new battery I get fan spin and with battery connected or disconnected it shows charging on the screen - I guess thats not right

no boot - with charger I can only get the battery icon in the middle of the screen, without the charger I get the icon asking to plug it in I have this usb c charger - idk if there is any led indicator on it Liquid damage around U7220, q8030, c8192, c8192 and L7030, not much - little battery...

Hi Some liquid damage to the board, cleaned up, new battery, new 821-00614-a flex cable. Unit asks to be plugged in, when plugged in shows its charging but never goes beyond that. Any pointers? Thank you in advance

Hi Slight liquid damage, wasnt detecting the battery Redone Q7130 and charging works, but the touchpad stopped working after login, tried new flex cable same, then noticed that Q4800 was a bit dodgy (could be my fault while redoing q7130) Replaced Q4800 but same :/ Any pointers?

ok PM_PWRBTN_L drops from 3.41v to 0.14v. I only have multimeter I hope thats ok

Yes, its charging the battery I dont think I have this SMC, I guess I will just get another board :/ Shame

Hi No life at all even trying smc bypass :(

Ok, got the charger Unfortunately PM_BATLOW_L still at 0v

Hi, Clients battery expanded and I replaced it. Booted, unit was waking from hibernation but was stuck, force powered it down and it wont come up since. No chime no fan. Client had 3rd party charger. Board looks fine - cant see any cracks/burns. Charger goes from green to orange with battery...

Ok so all the SPI Bus Series Termination resistors have values as per schematics U1950 3 - 0.162v up and down a bit 7 - 0.168v then up to 0.190v then down again PPBUS_G3H - 8.59v PP3v42_g3h - 3.42v PP5V_S0 - 5v PP1v05_S0 - 0.4 v - changed U1930 thinkink that this is the problem but still...

2informaticos, please excuse my ignorance here. I still don't get enough macbooks in to have a real experience, thank you for your patience. Let me dig deeper and hopefully I will be able to get all the info

Hi Another Air, liquid ingress present in one area only, blob stretching from U7600 down to U7870 and to Y1915. It was dead ( just one wire circuit working) Cleaned it up with crest and I am getting spin but no chime nor picture. Nothing really pops up, all bits look good/shiny Please assist :)...

Installed HWMonitor, GPU Die 129C, GPU 2 Heatsink 2 129 C. Not sure if this one doesnt have sensors or is something really wrong

OK, Unengine runs ok but shows 129 C temp - could that be anything?

I did both ASD, there is no gpu issue as far as I can tell. It feels like there is some "static" that needs "draining" before it can start. If I remove ram and pop it back in, it starts working, I will plug external disk, it works, keep bashing keys on the keyboard, it works. After that, it...

ASD passes :/ run it a few times. Reflowing GMUX sounds random - any reasoning behind it?

After an hour off, it does the same again :/

Yes it does work! It works after shutting down as well. What do you think is wrong?

New sata cable in but unfortunately, same thing happens. Dont know which direction to go here really? Constantly pressing on the keyboard somehow makes it boot, I am guessing I am draining something by pressing??? Its a real mystery for me BTW, I can boot via usb from the same disk, so I am...
