We have not :( Don't have a spare on hand and this customer wants there device back asap.

They all work. Bluetooth even works as well.

We got in a customers Macbook with the WiFi greyed out and we figured it was either the module or the possibly the ribbon that connects the motherboard to the IO board. We replaced both and tried SMC resets, but still getting WiFi greyed out..... Any ideas on what we can try next? Device is...

I connected the MB to the battery I had in stock from a used system and let it sit plugged in over the weekend.... came in this morning and the fans were spinning at 100%. Still have too hook up a screen and keyboard, but there is life.... Charging light stays green no matter what though. May...

Not sure honestly. Was just sent in and customer said it would not turn on.... just died. Board looks clean, no water damage or broken off components. I get a green light when connected to the OEM AC adapter and no battery and the same solid green light when connected to a battery.

Got a customer who sent me only the motherboard and said it will not boot, no fans. Is it possible to "Prompt to boot" this board? I have an 80W adapter and battery here, but no shell to put it in. Just need to make sure I fix the fans not kicking on apparently.

What are the chances the SMC is the fault? It still boots and SMC reset shows to work... just does not fix the problem. I have not tried replacing an SMC before, but can probably do it as I do most other IC's on iPhones.

Do I need to have this customer go to Apple to get taken care of? I can't seem to locate the issue and she would like to get her device back soon. Other option is to replace the while motherboard I guess.

It does work without the battery no problem at all. We have tried 3 batteries now, one which was her original, one that was our stock battery, and another battery from a known good system.

Ok... Here we go : AMON Battery Only = 0V AMON Battery and Charger = 230mV AMON Charger Only = 250mV BMON Battery Only = 155mV BMON Battery and Charger = 50mV BMON Charger Only = 51mV

Not sure which mode you want me to test CHGR_A / BMON in, but here are the diode mode readings : CHGR_AMON = 0.726 CHGR_BMON = 0.733 Pin 17 - 18 Resistance : 3.4 Ohms Pin 27 - 28 Resistance : 20.4 Ohms

Oh crap, miss read that... :P Charger and battery = 12.57 for about 4 seconds, then drops to 11.75V over 3 or 4 seconds, then back to 12.57V Charger Only = 12.57V

Yes, battery only. Not powered on since it will not power on without a charger plugged in.

Here are my findings.... SDA = 0.528 SCL = 0.530 PPBUS_G3H = 11.68V 3V42_G3H = 3.397V

Hello all! First post! I have a customer who has brought in a water damaged Macbook and this one has me lost.... Customer came in stating the system booted fine with the charger plugged in and when she unplugged it, it would instantly turn off. After going over the board thoroughly, there...
