Yes, battery charges at the beginning after connecting the battery. If I disconnect the charger and plug it back, the battery stops to charge. Yes, both ports on both charger side are same.

Good morning, everyone. I received this MacBook for repair; it turns on but doesn't charge. The USB-C ports weren't working, and the AMP meter is cycling. After inspecting the logic board, I found that C5202 was blown, and PDCIN_AON_CHGR_R was shorted. I replaced the capacitor, and now it gets...

Hi everyone. CPU VCore present. Fan spins on then off then on and stays on full speed. No USB activity light turns on but not blinking. PPVCC_S0_CPU - 1.69V steady Very minor liquid on U1930 pin 6. U1930 replaced. The rest of the board is clean. Mac started to boot to the system and works...

TL866II Plus automatically changes the voltage. I forgot to take a picture of the error message. I will flash it again.

I'm using the TL866II Plus, but it doesn't have the profile for the IC AT25SF321, so I just remove the IC MX25U3235F from another logicboard that matches the schematics and flashed the firmware. Apple Cong. gives another error message and still not working. Should I be looking at why PP3V3_S5...

Do you have the firmware, please?

Just tried another good battery and SMC reset and same issue. This is the message it gets if leave Apple Configurator trying after 20 minutes.

I came to this post as I had exactly the same issue and symptoms. All EDP line is OK. The problem was the screen cable had a tiny crack on it just visible on the microscope.

This Mac was left in a humid and freezing environment overnight, and the next day it stopped working. There are no signs of corrosion or liquid damage. When I plug in the charger, the voltage goes to 20V, and the amps vary between 0.07a and 0.9a. After a few seconds, it drops to 0.03A, rises...

I've checked the FPC screen connector J8500 and on pin 36 - I2C_ALS_SCL is shorted 5.3ohm diode mode 0. The normal diode measurement on this pin is 0.463 according to another logic board. This line goes to a 1.1K resistor R5316 pin 1 PP1V8_G3S and pin 2 receives the signal (I2C_ALS_SCL) from T2...

I use to place the black cover that goes on top the battery board between the battery Connector to isolate it. Can the flex cable connected cause any damage?

I think I left the flex cable plugged in. Just disconnected the battery.

The Mac came in for a screen replacement. I've replaced the screen it stops working. Trackpad clicking in a loop. I've replaced screens on a hundreds of Macs and never had this issue. Getting 20V and 0.0230A LogicBoard was stand-alone. All AWAKE and SLP are cycling every 14 sec PP1V2_AWAKE -...

Hi, we have an A1990, i9 & Radeon 560X. Before it was freezing every few seconds, almost as if failing SSD, even on external macOS installation. I have tried a clean reinstall, revive + restore T2 firmware and it now works fine, other than it seems to kernel panic after some time in sleep...

Got this kernel panic screen once.

C7020 – 3.3 ohms C7023 – 2.7 ohms I could not install the system again on internet mode. Every time it goes to globe and after Apple logo it reboots. I enter in Target disk mode and cloned the system from another mac, and it boots to the system again. (Battery and Touchpad disconnected) Only...

I've tried to dfu revive and restore in many ways. With and without battery, touchpad. Nothing works. I've connected everything and done dfu revive and halfway in the process I've disconnected the battery flex cable. It went all the process and back to life. But still same issue. Turns on and...

I've tried to restore and revive and no results. The problem now is that it won't turn on even with batt and touchpad disconnected. T2 firmware is corrupted. Any ideas on this, please?

Hi, everyone. Hope you can give some light on this issue. Got this MacBook with no display. When disconnecting the battery and touchpad it boots to the system, but if either is connected it will not display, or sometimes the Apple logo and kernel panic. I've replaced the touchpad and battery and...

Okay. Thanks for your help. I guess this is a BER now.
